Definitions

  • the present invention relates to a gas supply valve for supplying and regulating the flow of gas to a burner of a gas cooking appliance.
  • JP-A-H11304158 forms the basis for the two-part formulation of claim 1.
  • the regulating cone is driven in rotation by an operating member which extends along the longitudinal axis.
  • This operating member also moves in translation along the longitudinal axis.
  • the maneuvering member can cooperate directly or indirectly with means producing a slight rattling during rotation of the maneuvering member. This allows the user who manipulates an adjustment knob coupled to the maneuvering member to have a haptic perception of closed and open positions in the full flow position when rotating the latter.
  • the positions of the adjustment button and of the maneuvering member are not stable, fixed and repeatable positions associated respectively with a determined gas flow rate for the user.
  • the operating member passes through a housing which is mounted on the body of the valve and which comprises means for guiding the operating member in rotation at least partially through this housing.
  • the body is generally made by foundry, stamping or extrusion in a metallic material and machined.
  • the bypass member is in the form of a needle arranged in a rotatable manner in another cavity along the longitudinal axis.
  • the needle comprises a head provided with an imprint, a distal end having a substantially conical shape and a passage passing through the body thereof.
  • a tool such as a screwdriver in order to be able to turn the needle and ensure that the section of the passage is more or less reduced.
  • the gas valve may also include a flap which is rotatably arranged in yet another cavity of longitudinal axis so as to be able to adapt the valve to a type of gas, such as natural gas or petroleum gas.
  • Natural gas with the GN logo has a lower calorific value
  • petroleum gas which mainly comprises propane or butane, and with the GP logo, has a higher calorific value.
  • Petroleum gas is typically available in cylinders. The user can adapt his supply valve according to the supply equipment at his disposal.
  • the flap comprises a head with an indentation intended to receive a tool such as a screwdriver to drive it in rotation.
  • the valve also comprises a cocking member intended to be arranged in a duct arranged under the regulating cone.
  • the cocking member is elongated between two ends which respectively comprise an arm. One arm cooperates with a lower end of the regulating cone and the other arm cooperates with the safety solenoid valve. When the maneuvering member is actuated, this causes the arm to move via the regulating cone which causes the cocking member to rotate and the other arm in turn moves a pin located upstream of the safety solenoid valve.
  • the body of the supply valve is intended to be fixed on a gas supply rail of the cooking appliance.
  • a clamping flange is mounted on the body and is secured to a counter flange surrounding at least in part the substantially cylindrical supply ramp.
  • this valve comprises many parts to be handled with tools so as to calibrate or regulate the gas flow, which does not facilitate the use of such a gas supply valve.
  • a first objective of the present invention is to provide a gas valve that is simpler to use and more economical.
  • Another objective is to obtain the same flow rate (heating power of the burner) for two types of gas having a different calorific value and this for the same determined position of an operating member.
  • Another object of the invention is to adjust the gas flow and to adapt the supply valve to a type of gas in a single gesture.
  • Another object of the invention is to associate a gas flow with a position of the maneuvering member in a stable and repeatable manner.
  • this solution makes it possible to achieve the aforementioned objective.
  • a single regulator member to be able to adapt the valve to a type of gas by closing or opening cavities or channels so as to authorize or interrupt additional circulation of gas from the inlet to the outlet while can regulate the flow.
  • the regulating member and the corridor are configured so as to have a substantially identical overall power delivered to the burner for different types of gas whether the regulating member is in its first or its second position and this for the same position of the regulating cone . In this way, we obtain the same heating power for different types of gas at the same given position. This is all the more important and remarkable when the regulating cone occupies intermediate positions where the gas flow rate is less than the full flow rate. Indeed, more channel sections are open when the regulator member is in the first position.
  • the invention also relates to a gas supply system for a gas cooking appliance, the system comprising at least one supply ramp and at least one gas valve having any one of the preceding characteristics, the gas valve being mounted on the feed ramp, the system further comprising a counter flange which is arranged so as to at least partially surround the supply rail and to be fixed at least to the casing by means of fixing means.

Description

Domaine de l'inventionField of invention

La présente invention concerne un robinet d'alimentation de gaz permettant d'alimenter et de réguler le débit de gaz vers un brûleur d'un appareil de cuisson à gaz.The present invention relates to a gas supply valve for supplying and regulating the flow of gas to a burner of a gas cooking appliance.

Arrière-plan techniqueTechnical background

Des robinets de gaz sont connus des documents JP-A-H11304158 , US-A-3255965 , US-A-4108370 et JP-A-2012002294 . JP-A-H11304158 forme la base pour la formulation en deux parties de la revendication 1.Gas taps are known from the documents JP-A-H11304158 , US-A-3255965 , US-A-4108370 and JP-A-2012002294 . JP-A-H11304158 forms the basis for the two-part formulation of claim 1.

De manière générale, un robinet d'alimentation de gaz pour les appareils de cuisson de type cuisinière, table à gaz ou barbecue à gaz comprend :

  • un corps pourvu d'une entrée de gaz, d'une sortie de gaz et de plusieurs canaux, cavités ou chambres par lesquels le gaz peut circuler de l'entrée à la sortie de gaz,
  • une électrovanne de sécurité agencée dans une chambre et coopérant avec un dispositif de connexion,
  • un cône de régulation agencé de manière rotative dans une des cavités suivant un axe longitudinal de manière à réguler le débit de gaz entre une position minimale où le robinet est fermé et une position maximale où le robinet est ouvert avec un débit de gaz réduit, le cône de régulation pouvant encore occuper au moins une position intermédiaire de plein débit entre les positions minimale et maximale, et
  • un organe de dérivation permettant de calibrer un débit réduit lorsque le robinet est configuré pour fonctionner avec du gaz naturel ou du gaz de pétrole.
In general, a gas supply valve for cooking appliances such as a stove, gas hob or gas barbecue includes:
  • a body provided with a gas inlet, a gas outlet and several channels, cavities or chambers through which the gas can flow from the gas inlet to the gas outlet,
  • a safety solenoid valve arranged in a chamber and cooperating with a connection device,
  • a regulating cone rotatably arranged in one of the cavities along a longitudinal axis so as to regulate the flow of gas between a minimum position where the valve is closed and a maximum position where the valve is open with a reduced gas flow, the regulating cone which can still occupy at least one intermediate position of full flow between the minimum and maximum positions, and
  • a bypass device making it possible to calibrate a reduced flow rate when the valve is configured to operate with natural gas or petroleum gas.

Le cône de régulation est entraîné en rotation par un organe de manœuvre qui s'étend suivant l'axe longitudinal. Cet organe de manœuvre se déplace également en translation suivant l'axe longitudinal. L'organe de manœuvre peut coopérer directement ou indirectement avec des moyens réalisant un léger cliquetis lors de la rotation de l'organe de manœuvre. Cela permet à l'utilisateur qui manipule un bouton de réglage couplé à l'organe de manœuvre d'avoir une perception haptique de positions fermée et ouverte à la position plein débit lors de la rotation de celui-ci. Toutefois, il est difficile pour l'utilisateur de savoir à quel débit de gaz est associée la position du bouton de réglage en actionnant ce dernier (entre une position plein débit et de débit réduit). En particulier, les positions du bouton de réglage ainsi que de l'organe de manœuvre ne sont pas des positions stables, fixes et répétables associées respectivement à un débit de gaz déterminé pour l'utilisateur.The regulating cone is driven in rotation by an operating member which extends along the longitudinal axis. This operating member also moves in translation along the longitudinal axis. The maneuvering member can cooperate directly or indirectly with means producing a slight rattling during rotation of the maneuvering member. This allows the user who manipulates an adjustment knob coupled to the maneuvering member to have a haptic perception of closed and open positions in the full flow position when rotating the latter. However, it is difficult for the user to know which gas flow is associated with the position of the adjustment button by activating this last (between a full flow and a reduced flow position). In particular, the positions of the adjustment button and of the maneuvering member are not stable, fixed and repeatable positions associated respectively with a determined gas flow rate for the user.

L'organe de manœuvre traverse un carter qui est monté sur le corps du robinet et qui comprend des moyens de guidage en rotation de l'organe de manœuvre traversant au moins en partie ce carter. Le corps est généralement réalisé par fonderie, matriçage ou extrusion dans un matériau métallique et usiné.The operating member passes through a housing which is mounted on the body of the valve and which comprises means for guiding the operating member in rotation at least partially through this housing. The body is generally made by foundry, stamping or extrusion in a metallic material and machined.

L'organe de dérivation se présente sous la forme d'un pointeau agencé de manière rotative dans une autre cavité suivant l'axe longitudinal. Le pointeau comprend une tête pourvue d'une empreinte, une extrémité distale ayant une forme sensiblement conique et un passage traversant le corps de celui-ci. Pour calibrer le débit de gaz, l'utilisateur emploie un outil tel qu'un tournevis afin de pouvoir tourner le pointeau et faire en sorte que la section du passage soit plus ou moins réduite.The bypass member is in the form of a needle arranged in a rotatable manner in another cavity along the longitudinal axis. The needle comprises a head provided with an imprint, a distal end having a substantially conical shape and a passage passing through the body thereof. To calibrate the gas flow, the user uses a tool such as a screwdriver in order to be able to turn the needle and ensure that the section of the passage is more or less reduced.

Le robinet de gaz peut comprendre également un volet qui est agencé de manière rotative dans encore une autre cavité d'axe longitudinal de manière à pouvoir adapter le robinet à un type de gaz, tel que le gaz naturel ou le gaz de pétrole. Le gaz naturel siglé GN a un pouvoir calorifique inférieur tandis que le gaz de pétrole qui comprend en majorité du propane ou du butane, et siglé GP, a un pouvoir calorifique plus élevé. Le gaz de pétrole est typiquement disponible en bouteille. L'utilisateur peut adapter son robinet d'alimentation en fonction de l'équipement d'alimentation à sa disposition. Pour cela, le volet comprend une tête avec une empreinte destinée à recevoir un outil tel qu'un tournevis pour l'entraîner en rotation.The gas valve may also include a flap which is rotatably arranged in yet another cavity of longitudinal axis so as to be able to adapt the valve to a type of gas, such as natural gas or petroleum gas. Natural gas with the GN logo has a lower calorific value, while petroleum gas, which mainly comprises propane or butane, and with the GP logo, has a higher calorific value. Petroleum gas is typically available in cylinders. The user can adapt his supply valve according to the supply equipment at his disposal. For this, the flap comprises a head with an indentation intended to receive a tool such as a screwdriver to drive it in rotation.

Le robinet comprend également un organe d'armement destiné à être agencé dans un conduit agencé sous le cône de régulation. L'organe d'armement est allongé entre deux extrémités qui comprennent respectivement un bras. Un bras coopère avec une extrémité inférieure du cône de régulation et l'autre bras coopère avec l'électrovanne de sécurité. Lors de l'actionnement de l'organe de manœuvre celui-ci provoque le déplacement du bras via le cône de régulation qui entraîne la rotation de l'organe d'armement et l'autre bras déplace à son tour un pion situé en amont de l'électrovanne de sécurité.The valve also comprises a cocking member intended to be arranged in a duct arranged under the regulating cone. The cocking member is elongated between two ends which respectively comprise an arm. One arm cooperates with a lower end of the regulating cone and the other arm cooperates with the safety solenoid valve. When the maneuvering member is actuated, this causes the arm to move via the regulating cone which causes the cocking member to rotate and the other arm in turn moves a pin located upstream of the safety solenoid valve.

Le corps du robinet d'alimentation est destiné à être fixé sur une rampe d'alimentation de gaz de l'appareil de cuisson. A cet effet une bride de serrage est montée sur le corps et est solidarisée à une contre bride entourant au moins en partie la rampe d'alimentation sensiblement cylindrique.The body of the supply valve is intended to be fixed on a gas supply rail of the cooking appliance. For this purpose a clamping flange is mounted on the body and is secured to a counter flange surrounding at least in part the substantially cylindrical supply ramp.

En plus des inconvénients susmentionnés, ce robinet comprend de nombreuses pièces à manipuler avec des outils de manière à calibrer ou réguler le débit de gaz ce qui ne facilite pas l'utilisation d'un tel robinet d'alimentation de gaz.In addition to the aforementioned drawbacks, this valve comprises many parts to be handled with tools so as to calibrate or regulate the gas flow, which does not facilitate the use of such a gas supply valve.

Résumé de l'inventionSummary of the invention

Un premier objectif de la présente invention est de fournir un robinet de gaz plus simple d'utilisation et plus économique.A first objective of the present invention is to provide a gas valve that is simpler to use and more economical.

Un autre objectif est d'obtenir un même débit (puissance de chauffe du brûleur) pour deux types de gaz ayant un pouvoir calorifique différent et ce pour une même position déterminée d'un organe de manœuvre.Another objective is to obtain the same flow rate (heating power of the burner) for two types of gas having a different calorific value and this for the same determined position of an operating member.

Un autre objectif de l'invention est de régler le débit de gaz et d'adapter le robinet d'alimentation à un type de gaz en un seul geste.Another object of the invention is to adjust the gas flow and to adapt the supply valve to a type of gas in a single gesture.

Un autre objectif de l'invention est d'associer un débit de gaz à une position de l'organe de manœuvre de manière stable et répétable.Another object of the invention is to associate a gas flow with a position of the maneuvering member in a stable and repeatable manner.

Nous parvenons à cet objectif conformément à l'invention grâce à un robinet d'alimentation de gaz, suivant un premier aspect, et comprenant :

  • un corps pourvu d'une entrée de gaz, d'une sortie de gaz entre lesquelles circule un gaz, le corps comprenant en outre un premier canal, un deuxième canal, une première cavité, et une deuxième cavité par lesquelles peut circuler le gaz de l'entrée de gaz à la sortie de gaz, le premier canal débouchant d'une part dans la première cavité et d'autre part dans la sortie de gaz, le deuxième canal débouchant d'une part dans la deuxième cavité et d'autre part dans la première cavité,
  • un cône de régulation logé dans la première cavité du corps et de manière rotative autour d'un axe longitudinal X pour réguler le débit de gaz entre une position minimale et une position maximale, l'entrée de gaz étant en communication fluidique avec la première cavité, et
  • un organe régulateur agencé dans la deuxième cavité et comprenant un passage interne avec une entrée et une première sortie,
le corps comprenant un couloir qui débouche d'une part, dans la première cavité et d'autre part, dans la deuxième cavité et l'organe régulateur étant agencé de manière rotative autour d'un axe parallèle à l'axe longitudinal entre:
  • ∘ une première position dans laquelle l'organe régulateur libère une sortie du couloir,
  • ∘ une deuxième position dans laquelle l'organe régulateur obture la sortie du couloir.
We achieve this objective in accordance with the invention thanks to a gas supply valve, according to a first aspect, and comprising:
  • a body provided with a gas inlet, a gas outlet between which a gas circulates, the body further comprising a first channel, a second channel, a first cavity, and a second cavity through which the gas of the gas inlet to the gas outlet, the first channel opening on the one hand into the first cavity and on the other hand into the gas outlet, the second channel opening on the one hand into the second cavity and on the other leaves in the first cavity,
  • a regulating cone housed in the first cavity of the body and rotatably about a longitudinal axis X for regulating gas flow between a minimum position and a maximum position, the gas inlet being in fluid communication with the first cavity , and
  • a regulating member arranged in the second cavity and comprising an internal passage with an inlet and a first outlet,
the body comprising a corridor which opens on the one hand, into the first cavity and on the other hand, into the second cavity and the regulating member being arranged in a rotatable manner around an axis parallel to the longitudinal axis between:
  • ∘ a first position in which the regulating organ releases an exit from the corridor,
  • ∘ a second position in which the regulating organ closes off the corridor exit.

Ainsi, cette solution permet d'atteindre l'objectif susmentionné. En particulier, une telle configuration permet avec un seul organe régulateur de pouvoir adapter le robinet à un type de gaz en fermant ou ouvrant des cavités ou canaux de manière à autoriser ou interrompre une circulation additionnel de gaz depuis l'entrée vers la sortie tout en pouvant réguler le débit. L'organe régulateur et le couloir sont configurés de manière à avoir une puissance délivrée au brûleur globale sensiblement identique pour des types de gaz différents que l'organe régulateur soit dans sa première ou sa deuxième position et ce pour une même position du cône de régulation. De la sorte, nous obtenons une même puissance de chauffe pour différents types de gaz à une même position donnée. Cela est d'autant plus important et remarquable lorsque le cône de régulation occupe des positions intermédiaires où le débit de gaz est inférieur au plein débit. En effet, plus de sections de canaux sont ouvertes lorsque l'organe régulateur est dans la première position.Thus, this solution makes it possible to achieve the aforementioned objective. In particular, such a configuration makes it possible, with a single regulator member, to be able to adapt the valve to a type of gas by closing or opening cavities or channels so as to authorize or interrupt additional circulation of gas from the inlet to the outlet while can regulate the flow. The regulating member and the corridor are configured so as to have a substantially identical overall power delivered to the burner for different types of gas whether the regulating member is in its first or its second position and this for the same position of the regulating cone . In this way, we obtain the same heating power for different types of gas at the same given position. This is all the more important and remarkable when the regulating cone occupies intermediate positions where the gas flow rate is less than the full flow rate. Indeed, more channel sections are open when the regulator member is in the first position.

La première cavité 10 comprend une première ouverture 11 et une deuxième ouverture qui sont opposées suivant l'axe longitudinal. La première ouverture 11 débouche sur une surface supérieure 13 du corps (en relation avec la figue 2). La deuxième ouverture débouche dans un premier conduit 14 formé à l'intérieur du corps également. Le premier conduit 14 comprend une entrée 14a et une sortie 14b. L'entrée du premier conduit 14 débouche sur une troisième face 7 du corps. Avantageusement l'entrée 14a est obturée par un élément de fermeture 15. Quant à la sortie 14b du premier conduit, celle-ci débouche dans la première cavité 10. De manière avantageuse, l'élément de fermeture 15 est une bille.With reference to figure 2 , 3 and 4 , the body 2 comprises a first cavity 10 with axis A parallel to the longitudinal axis X. The first cavity 10 comprises a first opening 11 and a second opening which are opposite each other along the longitudinal axis. The first opening 11 opens onto an upper surface 13 of the body (in relation to FIG. 2). The second opening opens into a first duct 14 also formed inside the body. The first conduit 14 includes an inlet 14a and an outlet 14b. The inlet of the first duct 14 leads to a third face 7 of the body. Advantageously, the inlet 14a is closed off by a closure element 15. As for the outlet 14b of the first duct, this opens into the first cavity 10. Advantageously, the closure element 15 is a ball.

La première cavité 10 communique fluidiquement avec la sortie de gaz 4. En particulier, la première cavité 10 comprend une entrée 10a formée par la deuxième ouverture. La première cavité 10 comprend une première sortie 16a qui communique avec la sortie de gaz 4. Le corps comprend un premier canal 17 avec une entrée 17a et une sortie 17b. La première sortie 16a de la première cavité 10 est reliée à l'entrée 17a du premier canal 17 et la sortie 17b du premier canal 17 est reliée à la sortie de gaz 4.The first cavity 10 communicates fluidly with the gas outlet 4. In particular, the first cavity 10 comprises an inlet 10a formed by the second opening. The first cavity 10 comprises a first outlet 16a which communicates with the gas outlet 4.

En référence à la figure 5, le robinet 1 comprend un cône de régulation 21 configuré de manière à réguler le débit de gaz. Le cône de régulation 21 s'étend suivant un axe C entre une extrémité proximale 22 et une extrémité distale 23. Le cône 21 est destiné à être logé dans la première cavité 10 et de manière rotative autour de son axe C. En situation d'installation, l'axe C du cône de régulation est coaxial avec l'axe longitudinal X. Pour cela, le cône de régulation 21 comprend une première portion 24 avec une surface externe 25 de forme complémentaire avec une surface interne de la première cavité. La première portion 24 du cône est sensiblement conique ou tronconique. Afin de garantir la rotation du cône de régulation et notamment un glissement dans la première cavité 10, un lubrifiant est prévu dans la première cavité 10. Le lubrifiant s'étale entre la surface interne et la surface externe 25. D'autres moyens garantissant la rotation du cône de régulation sont bien entendu possibles. Le cône de régulation 21 comprend en outre une deuxième portion 27 ayant une forme de cylindre droit. La deuxième portion 27 prolonge la première portion 24 suivant l'axe C. La deuxième portion 27 est destinée à s'étendre à l'extérieur du corps de robinet et depuis la surface supérieure 13.With reference to the figure 5 , the valve 1 comprises a regulating cone 21 configured so as to regulate the flow of gas. The regulating cone 21 extends along an axis C between a proximal end 22 and a distal end 23. The cone 21 is intended to be housed in the first cavity 10 and rotatably around its axis C. In a situation of installation, the axis C of the regulating cone is coaxial with the longitudinal axis X. For this, the regulating cone 21 comprises a first portion 24 with an outer surface 25 of complementary shape with an inner surface of the first cavity. The first portion 24 of the cone is substantially conical or frustoconical. In order to guarantee the rotation of the regulating cone and in particular a sliding in the first cavity 10, a lubricant is provided in the first cavity 10. The lubricant spreads between the internal surface and the external surface 25. Other means guaranteeing the rotation of the regulating cone are of course possible. The regulating cone 21 further comprises a second portion 27 having the shape of a right cylinder. The second portion 27 extends the first portion 24 along the axis C. The second portion 27 is intended to extend outside the valve body and from the upper surface 13.

Comme nous pouvons le voir sur la figure 5, le cône de régulation 21 est creux. Le cône comprend un passage 28 qui est formé de manière traversant dans la paroi du cône de régulation et sur au moins une partie de la circonférence du cône de régulation autour de l'axe C. En d'autres termes, le passage 28 débouche d'une part à l'intérieur du cône et d'autre part, à l'extérieur du cône. Le passage 28 présente une hauteur h1 suivant l'axe C du cône qui est variable suivant la circonférence du cône de régulation. En particulier, le passage 28 croît en hauteur progressivement suivant un sens selon la circonférence de la paroi du cône. Le passage 28 est prévu sur la première portion 24 du cône de régulation 21.As we can see on the figure 5 , the regulating cone 21 is hollow. The cone includes a passage 28 which is formed through the wall of the regulation cone and over at least a part of the circumference of the regulation cone around the axis C. In other words, the passage 28 opens out of on the one hand inside the cone and on the other hand outside the cone. The passage 28 has a height h1 along the axis C of the cone which is variable along the circumference of the regulating cone. In particular, the passage 28 increases in height gradually in a direction along the circumference of the wall of the cone. The passage 28 is provided on the first portion 24 of the regulating cone 21.

Le cône de régulation 21 pivote autour de l'axe longitudinal X pour réguler le débit de gaz entre une position minimale et une position maximale. La position minimale correspond à la fermeture du robinet, c'est-à-dire que le gaz n'atteint pas la sortie de gaz 4. La position maximale correspond à l'ouverture du robinet, c'est-à-dire que le gaz peut atteindre la sortie de gaz 4. La position maximale correspond également à une position de débit réduit de gaz. Le cône de régulation 21 peut occuper une première position intermédiaire correspondant au plein de débit gaz et une deuxième position intermédiaire correspondant à un débit de gaz intermédiaire situé entre le débit réduit et le plein débit. Dans la positon minimale, le cône de régulation 21 est positionné à une position angulaire de 0°. Dans la première position intermédiaire, le cône de régulation est situé à une position angulaire de 90°. Dans la deuxième position intermédiaire, le cône de régulation 21 se trouve dans une position angulaire comprise entre 120° et 260° (ou éventuellement entre 120° et 200°. Enfin, dans la position maximale, le cône de régulation se trouve dans une position de l'ordre de 210° ou éventuellement de 280°. En d'autres termes, le robinet de gaz est ouvert suivant une plage d'ouverture comprise entre 90° et 210° ou entre 90° et 280°. Et le cône de régulation 21 permet l'ouverture du robinet entre la position minimale (mais conventionnellement un peu avant la première position intermédiaire) et la position maximale.The regulating cone 21 pivots around the longitudinal axis X to regulate the gas flow between a minimum position and a maximum position. The minimum position corresponds to the closing of the tap, i.e. the gas does not reach the gas outlet 4. The maximum position corresponds to the opening of the tap, i.e. the gas can reach the gas outlet 4. The maximum position also corresponds to a reduced gas flow position. The regulating cone 21 can occupy a first intermediate position corresponding to full gas flow and a second intermediate position corresponding to an intermediate gas flow situated between reduced flow and full flow. In the minimum position, the regulating cone 21 is positioned at an angular position of 0°. In the first intermediate position, the regulating cone is located at an angular position of 90°. In the second intermediate position, the regulation cone 21 is in an angular position between 120° and 260° (or possibly between 120° and 200°. Finally, in the maximum position, the regulation cone is in a position of the order of 210° or possibly 280°. In other words, the gas valve is open according to an opening range of between 90° and 210° or between 90° and 280°. And the cone of regulation 21 allows the valve to open between the minimum position (but conventionally slightly before the first intermediate position) and the maximum position.

Le cône de régulation 21 comprend une encoche 29 qui est formée dans la paroi du cône et qui s'étend suivant l'axe C. Cette encoche 29 est située en particulier sur la deuxième portion 27 du cône et est délimitée circonférentiellement de part et d'autre par une bordure 30 (à l'extrémité distale 23) du cône. L'encoche 29 traverse également la paroi de part et d'autre radialement par rapport à l'axe C du cône et débouche à l'intérieur du cône. Cette encoche 29 a une forme en U ou en C. De manière avantageuse, mais non limitativement, l'encoche 29 est située au même niveau (radialement par rapport à l'axe C) que la partie la plus élargie 28a du passage selon l'axe C du cône 21.The regulating cone 21 comprises a notch 29 which is formed in the wall of the cone and which extends along the axis C. This notch 29 is located in particular on the second portion 27 of the cone and is delimited circumferentially on both sides. the other by an edge 30 (at the distal end 23) of the cone. The notch 29 also crosses the wall on either side radially with respect to the axis C of the cone and emerges inside the cone. This notch 29 has a U or C shape. Advantageously, but not limitingly, the notch 29 is located at the same level (radially with respect to the axis C) as the widest part 28a of the passage along the axis C of cone 21.

Sur la figure 6 est illustré un organe de manœuvre 40 pour entraîner en rotation le cône de régulation 21. L'organe de manœuvre 40 se présente sous la forme d'une tige cylindrique à section circulaire. La tige s'étend entre une première extrémité 41 et une deuxième extrémité 42 suivant un axe D. La première extrémité 41 est destinée à être engagée dans un bouton de réglage (non représenté) manœuvré par un utilisateur lorsque celui-ci veut allumer ou éteindre le brûleur. La première extrémité 41 comprend un méplat 43 destiné à s'engager dans un trou borgne de forme correspondante du bouton de réglage pour bloquer la rotation de la tige dans le bouton de réglage. Le méplat 43 est parallèle à l'axe D de la tige. La tige comprend à son deuxième extrémité un ergot 44 qui s'étend radialement depuis le corps de la tige. La deuxième extrémité 42 comprend également un renfoncement suivant l'axe D qui vient en appui contre la tête d'un élément de rappel logé à l'intérieur du cône de régulation 21. L'ergot 44 est conformé pour s'introduire dans l'encoche 29 du cône de régulation de sorte que ce dernier soit solidaire au moins en rotation avec l'organe de manœuvre 40 (la tige). L'ergot 44 présente une forme de cylindre droit. Bien entendu, l'ergot peut présenter une autre forme dès lors que celui-ci puisse s'introduire dans l'encoche 29. L'ergot 44 et l'organe de manœuvre se déplacent également en translation suivant l'axe longitudinal. L'élément de rappel favorise le retour en position de la tige. L'élément de rappel est un ressort de compression par exemple. L'organe de manœuvre 40 occupe la même position que le cône de régulation 21 puisqu'ils sont solidaire en déplacement.On the figure 6 an operating member 40 is shown for driving the regulating cone 21 in rotation. The operating member 40 is in the form of a cylindrical rod with a circular section. The rod extends between a first end 41 and a second end 42 along an axis D. The first end 41 is intended to be engaged in an adjustment knob (not shown) operated by a user when the latter wants to turn on or off the burner. The first end 41 comprises a flat 43 intended to engage in a blind hole of corresponding shape of the adjustment button to block the rotation of the rod in the adjustment button. The flat 43 is parallel to the axis D of the rod. The rod comprises at its second end a lug 44 which extends radially from the body of the rod. The second end 42 also comprises a recess along the axis D which bears against the head of a return element housed inside the regulating cone 21. The lug 44 is shaped to be introduced into the notch 29 of the regulating cone so that the latter is integral at least in rotation with the operating member 40 (the rod). The lug 44 has the shape of a right cylinder. Of course, the lug can have another shape as long as it can be introduced into the notch 29. The lug 44 and the operating member also move in translation along the longitudinal axis. The return element promotes the return to position of the rod. The return element is a compression spring for example. The operating member 40 occupies the same position as the regulating cone 21 since they are integral in movement.

Le robinet 1 comprend un carter 50 monté sur le corps du robinet d'alimentation comme cela est visible sur les figures 1 et 7. Le carter 50 est connu sous la dénomination de « palier ». Le carter 50 comprend un matériau métallique. Un exemple de matériau métallique est l'aluminium, l'acier ou acier inoxydable. Avantageusement, le carter est réalisé à partir d'une tôle emboutie ou par fonderie. Le carter 50 comprend un fond 51 et une paroi latérale 52 s'élevant depuis le fond 51. Une embase 53 délimite une ouverture du carter qui est opposée au fond 51 suivant la hauteur du carter (suivant l'axe longitudinal). L'embase 53 comprend des trous traversants 54 (au niveau d'une oreille) d'axe parallèle à l'axe longitudinal X. Ces trous traversants 54 sont destinés à recevoir des moyens de fixation 55 pour la fixation du carter 50 sur le corps 2. Avantageusement, les moyens de fixation 55 comprennent des vis. Le fond 51 est traversé par un orifice 56 d'axe parallèle à l'axe longitudinal. En situation d'installation, l'axe de l'orifice est coaxial avec l'axe du cône de régulation ou de la première cavité. De même, le fond 51 est à distance de la surface supérieure 13. L'organe de manœuvre (ici la tige) traverse l'orifice 56 traversant. Avantageusement, le carter 50 comprend un manchon 57 creux qui délimite l'orifice 56 traversant et qui s'étend depuis le fond 51 suivant l'axe longitudinal X. Le manchon 57 permet de guider l'organe de manœuvre 40 en déplacement.The valve 1 comprises a casing 50 mounted on the body of the supply valve as can be seen in the figure 1 and 7 . The casing 50 is known under the name of “bearing”. Housing 50 includes a metallic material. An example of metallic material is aluminum, steel or stainless steel. Advantageously, the casing is made from stamped or foundry sheet metal. The casing 50 comprises a bottom 51 and a side wall 52 rising from the bottom 51. A base 53 delimits an opening of the casing which is opposite the bottom 51 along the height of the casing (along the longitudinal axis). The base 53 comprises through-holes 54 (at the level of an ear) with an axis parallel to the longitudinal axis X. These through-holes 54 are intended to receive fixing means 55 for fixing the casing 50 to the body. 2. Advantageously, the fixing means 55 comprise screws. The bottom 51 is traversed by an orifice 56 with an axis parallel to the longitudinal axis. In the installation situation, the axis of the orifice is coaxial with the axis of the regulating cone or of the first cavity. Similarly, the bottom 51 is at a distance from the upper surface 13. The operating member (here the rod) passes through the orifice 56 through. Advantageously, the casing 50 comprises a hollow sleeve 57 which delimits the through orifice 56 and which extends from the bottom 51 along the longitudinal axis X. The sleeve 57 makes it possible to guide the maneuvering member 40 in movement.

La paroi latérale 52 du carter 50 est pourvue d'un premier trou taraudé 58 d'axe E. Cet axe E est parallèle à l'axe transversal Y. Le premier trou taraudé 58 est destiné à recevoir des moyens de fixation 55 pour la fixation du robinet sur une rampe d'alimentation 60 comme cela est visible sur la figure 1. Un deuxième trou taraudé 61 (cf. figure 3) est agencé dans le corps du robinet et est destiné à recevoir des moyens de fixation 55 également. Dans le présent exemple, les moyens de fixation 55 comprennent des vis. Le deuxième trou taraudé 61 est d'axe parallèle à l'axe transversal. Les axes des premier et deuxième trous taraudés 58, 61 sont parallèles. Avantageusement, les axes sont définis dans un même plan (en situation d'installation). La figure 1 représente une contre bride 62 ayant deux trous lisses et traversants. La contre bride 62 est installée d'un côté de la rampe 60 et les vis sont insérées dans les trous lisses des brides et dans les premier et deuxième trous taraudés du robinet pour la fixation de l'ensemble et le maintien du robinet sur la rampe 60. Cette configuration évite la mise en place d'une bride de serrage supplémentaire pour coopérer avec la contre bride. De plus, la réalisation du premier trou taraudé dans le carter permet un gain de matière lequel engendre un gain économique.The side wall 52 of the housing 50 is provided with a first tapped hole 58 of axis E. This axis E is parallel to the transverse axis Y. The first tapped hole 58 is intended to receive fixing means 55 for fixing tap on a supply rail 60 as shown on the figure 1 . A second tapped hole 61 (cf. picture 3 ) is arranged in the valve body and is intended to receive fixing means 55 also. In the present example, the fixing means 55 comprise screws. The second tapped hole 61 has an axis parallel to the transverse axis. The axes of the first and second tapped holes 58, 61 are parallel. Advantageously, the axes are defined in the same plane (in installation condition). The figure 1 represents a counter flange 62 having two smooth and through holes. The counter flange 62 is installed on one side of the ramp 60 and the screws are inserted in the smooth holes of the flanges and in the first and second tapped holes of the valve for fixing the assembly and maintaining the valve on the ramp 60. This configuration avoids the installation of an additional clamping flange to cooperate with the counterflange. In addition, the realization of the first tapped hole in the casing allows a saving of material which generates an economic gain.

Le robinet 1 comprend un organe régulateur 65 reçu dans la deuxième cavité 20 de manière rotative entre une première position et une deuxième position. La deuxième cavité 20 comprend un orifice 66 (représenté sur la figure 2) qui débouche sur la surface supérieure 13 du corps. La deuxième cavité 20 comprend une première entrée 20a qui est reliée à la sortie 18b du deuxième canal 18. La première entrée 20a est opposée suivant l'axe longitudinal à l'orifice 66 (ou à l'opposé de la surface supérieure 13). La deuxième cavité 20 comprend en outre une première sortie 20b qui est reliée à la sortie de gaz 4 via un troisième canal 67. En d'autre termes, le troisième canal 67 débouche d'une part, dans la sortie de gaz 4 et d'autre part, dans la deuxième cavité 20.The valve 1 comprises a regulator member 65 received in the second cavity 20 rotatably between a first position and a second position. The second cavity 20 includes an orifice 66 (shown in the picture 2 ) which opens onto the upper surface 13 of the body. The second cavity 20 comprises a first inlet 20a which is connected to the outlet 18b of the second channel 18. The first inlet 20a is opposite along the longitudinal axis to the orifice 66 (or opposite the upper surface 13). The second cavity 20 further comprises a first outlet 20b which is connected to the gas outlet 4 via a third channel 67. In other words, the third channel 67 opens on the one hand, into the gas outlet 4 and d on the other hand, in the second cavity 20.

Sur la figure 3, la deuxième cavité 20 comprend suivant l'axe longitudinal X, une première partie 20d, une deuxième partie 20e et une troisième partie 20f. La deuxième cavité 20 est sensiblement cylindrique à section circulaire. La première partie 20d présente un diamètre D31 supérieur à celui de la deuxième partie 20e lequel a également un diamètre D32 supérieur au diamètre D33 de la troisième partie 20f. Le diamètre de la deuxième cavité est décroissant de l'orifice 66 à la première entrée 20aOn the picture 3 , the second cavity 20 comprises along the longitudinal axis X, a first part 20d, a second part 20e and a third part 20f. The second cavity 20 is substantially cylindrical with a circular section. The first part 20d has a diameter D31 greater than that of the second part 20e which also has a diameter D32 greater than the diameter D33 of the third part 20f. The diameter of the second cavity decreases from the orifice 66 to the first inlet 20a

Sur cette figure 3, le corps du robinet comprend également un couloir 104 qui débouche dans la deuxième cavité 20. Le couloir 104 comprend une entrée 104a qui est reliée à une troisième sortie 16c de la première cavité 10 et une sortie 104b qui est reliée à une deuxième entrée 20c de la deuxième cavité 20. Ce couloir 104 permet de fournir un débit de gaz additionnel lorsque le robinet est configuré pour fonctionner avec du GN.On this picture 3 , the faucet body also comprises a corridor 104 which opens into the second cavity 20. The corridor 104 comprises an inlet 104a which is connected to a third outlet 16c of the first cavity 10 and an outlet 104b which is connected to a second inlet 20c of the second cavity 20. This corridor 104 makes it possible to provide an additional gas flow when the valve is configured to operate with NG.

En référence à la figure 8, l'organe régulateur 65 s'étend suivant un axe principal F qui est coaxial avec l'axe B (et de l'axe longitudinal X) de la deuxième cavité 20 en situation d'installation. L'organe régulateur 65 comprend un corps de forme générale cylindrique et est creux. Le corps comprend une tête 68 et une extrémité libre 69 qui sont opposées suivant l'axe F. La tête 68 comprend une face 70 avec une empreinte 71 de manière à pouvoir entraîner l'organe régulateur en rotation. L'empreinte 71 peut avoir une forme en I, carrée ou en étoile pour recevoir un outil tel qu'un tournevis ayant une pointe adaptée à la forme de l'empreinte. L'organe régulateur 65 comprend un passage interne 72 (représenté en pointillé) qui débouche à l'extrémité libre 69 en formant une entrée 73. Cette dernière débouche dans la deuxième cavité 20 (en situation d'installation). L'organe régulateur 65 comprend un premier trou 74 qui débouche à la fois dans le passage interne 72 et sur la surface cylindrique extérieure 75 de l'organe régulateur. Le premier trou 74 défini une première sortie du passage interne. Avantageusement, l'organe régulateur comprend un deuxième trou 74' qui débouche à la fois dans le passage interne et sur la surface cylindrique extérieure. Ce deuxième trou défini donc une deuxième sortie du passage interne. Les premier et deuxième trous 74, 74' sont opposés radialement. Au moins l'un des premier et deuxième trous est relié à la sortie de gaz 4. Avantageusement, cette communication fluidique entre le passage interne et la sortie de gaz est réalisée au niveau du troisième canal 67.With reference to the figure 8 , the regulator member 65 extends along a main axis F which is coaxial with the axis B (and the longitudinal axis X) of the second cavity 20 in the installation situation. The regulator member 65 comprises a body of generally cylindrical shape and is hollow. The body comprises a head 68 and a free end 69 which are opposite along the axis F. The head 68 comprises a face 70 with an indentation 71 so as to be able to drive the regulating member in rotation. The imprint 71 can have an I-shape, square or star to receive a tool such as a screwdriver having a tip adapted to the shape of the impression. The regulator member 65 comprises an internal passage 72 (shown in dotted lines) which opens out at the free end 69 forming an inlet 73. The latter opens out into the second cavity 20 (in the installation situation). Regulator member 65 comprises a first hole 74 which opens both into internal passage 72 and onto outer cylindrical surface 75 of the regulator member. The first hole 74 defines a first exit from the internal passage. Advantageously, the regulator member comprises a second hole 74' which opens both into the internal passage and onto the external cylindrical surface. This second hole therefore defines a second outlet from the internal passage. The first and second holes 74, 74' are radially opposed. At least one of the first and second holes is connected to the gas outlet 4. Advantageously, this fluid communication between the internal passage and the gas outlet is carried out at the level of the third channel 67.

Comme nous pouvons le voir sur la figure 8, l'organe régulateur 65 comprend une gorge 76 formée sur la circonférence du corps et à proximité de la tête 68. La gorge est destinée à recevoir un élément d'étanchéité 77 de manière à combler un éventuel interstice entre la deuxième cavité 20 et l'organe régulateur 65. L'élément d'étanchéité 77 est avantageusement un joint torique centré sur l'axe de l'organe régulateur.As we can see on the figure 8 , the regulator member 65 comprises a groove 76 formed on the circumference of the body and close to the head 68. The groove is intended to receive a sealing element 77 so as to fill any gap between the second cavity 20 and the regulating member 65. The sealing element 77 is advantageously an O-ring centered on the axis of the regulating member.

L'organe régulateur 65 comprend une première portion de surface extérieure 78 qui présente une première hauteur h2 déterminée. Cette première portion de surface extérieure 78 est destinée à coopérer avec une première portion de surface interne de la deuxième cavité 20. En particulier, la première portion de surface extérieure 78 a une forme complémentaire à la première portion de surface interne de la deuxième partie 20e de la deuxième cavité 20. La première portion de surface extérieure 78 est portée par une première portion 80 du corps ayant un diamètre D1 supérieur à un diamètre D2 d'une deuxième portion 81 du corps. La première portion 80 est agencée en partie supérieure du ou des trous 74, 74' suivant l'axe F. Le ou les trous 74, 74' sont agencés sur la deuxième portion 81 du corps.The regulating member 65 comprises a first outer surface portion 78 which has a first determined height h2. This first outer surface portion 78 is intended to cooperate with a first inner surface portion of the second cavity 20. In particular, the first outer surface portion 78 has a shape complementary to the first inner surface portion of the second part 20e of the second cavity 20. The first outer surface portion 78 is carried by a first portion 80 of the body having a diameter D1 greater than a diameter D2 of a second portion 81 of the body. The first portion 80 is arranged in the upper part of the hole or holes 74, 74' along the axis F. The hole or holes 74, 74' are arranged on the second portion 81 of the body.

L'organe régulateur 65 comprend également une deuxième portion de surface extérieure 82 ayant une deuxième hauteur h4 prédéterminée. La deuxième hauteur h4 prédéterminée est inférieure à la première hauteur h2 prédéterminée de la première portion de surface extérieure 78. La deuxième portion de surface extérieure 82 est portée par une troisième portion 83 du corps ayant un diamètre D3 inférieur à celui de la deuxième portion 81.Regulator member 65 also includes a second outer surface portion 82 having a second predetermined height h4. The second predetermined height h4 is less than the first predetermined height h2 of the first outer surface portion 78. The second outer surface portion 82 is carried by a third portion 83 of the body having a diameter D3 less than that of the second portion 81 .

L'organe régulateur 65 comprend en outre un filet externe 84 complémentaire avec des filets interne de la deuxième cavité 20. Le filet externe 84 est réalisé sur une quatrième portion 85 du corps de l'organe régulateur. La quatrième portion 85 comprend un diamètre supérieur à celui de la première portion 80. En d'autres termes, le diamètre externe de l'organe régulateur est décroissant de la tête 68 à l'extrémité libre 69 (soit de la quatrième portion à la troisième portion) suivant l'axe F. De manière avantageuse, le filet externe 84 présente un filet métrique de type 4 (M5). Le diamètre extérieur de l'organe régulateur 65 avec le filet externe est de l'ordre de 4 mm.The regulator member 65 further comprises an external thread 84 complementary with internal threads of the second cavity 20. The external thread 84 is made on a fourth portion 85 of the body of the regulator member. The fourth portion 85 comprises a diameter greater than that of the first portion 80. In other words, the outer diameter of the regulator member decreases from the head 68 to the free end 69 (i.e. from the fourth portion to the third portion) along the axis F. Advantageously, the external thread 84 has a type 4 (M5) metric thread. The outside diameter of the regulator member 65 with the external thread is of the order of 4 mm.

L'organe régulateur 65 pivote autour de l'axe longitudinal X entre sa première position et sa deuxième position. Dans la première position, l'organe régulateur autorise la communication fluidique entre le couloir 104 et la sortie de gaz 4. La première position correspond au cas où le robinet est configuré pour être alimenté par du GN avec une circulation de gaz additionnel du couloir 104 à la sortie de gaz. A cet effet, la première et la deuxième sortie 74, 74' est/sont relié(e)s à l'entrée du troisième canal 67. La premier et/ou la deuxième sortie 74, 74' du passage interne 72 est/sont disposée(s) dans la deuxième partie 20e de la deuxième cavité 20 qui se trouve en communication fluidique avec le troisième canal 67. La sortie 104b du couloir 104 est en communication fluidique avec la deuxième cavité 20 (et en particulier avec la deuxième partie 20e de la deuxième cavité 20). En fonction de la position d'ouverture et de fermeture du robinet correspondant à une position minimale et une position maximale du cône de régulation 21, le premier canal 17 et/ou le deuxième canal 18 et/ou couloir 104 sont reliés et en communication fluidique avec la sortie de gaz 4.The regulator member 65 pivots around the longitudinal axis X between its first position and its second position. In the first position, the regulating member allows fluid communication between the corridor 104 and the gas outlet 4. The first position corresponds to the case where the valve is configured to be supplied by NG with additional gas circulation from the corridor 104 at the gas outlet. For this purpose, the first and the second output 74, 74' is/are connected to the input of the third channel 67. The first and/or the second output 74, 74' of the internal passage 72 is/are arranged in the second part 20e of the second cavity 20 which is in fluid communication with the third channel 67. The outlet 104b of the corridor 104 is in fluid communication with the second cavity 20 (and in particular with the second part 20e of the second cavity 20). Depending on the opening and closing position of the tap corresponding to a minimum position and a maximum position of the regulating cone 21, the first channel 17 and/or the second channel 18 and/or corridor 104 are connected and in fluid communication with gas outlet 4.

Dans la deuxième position, l'organe régulateur 65 interrompt la communication fluidique entre le couloir 104 et la sortie de gaz 4. La deuxième position correspond au cas où le robinet est configuré pour être alimenté par du GP et il n'y a pas de circulation de gaz additionnel. Dans ce cas, la troisième portion 82 du corps de l'organe régulateur 65 avec l'entrée 73 engagée au fond de la deuxième cavité 20 suivant l'axe longitudinal. En particulier, la deuxième portion 81 avec au moins une des première et deuxième sorties 74, 74' du corps se trouve au fond 86 de la deuxième partie 20e de la deuxième cavité 20. La hauteur de fermeture h2 de la première portion de surface extérieure 78 est supérieure à la hauteur de fermeture de la sortie 104b du couloir 104l. De même, la deuxième portion de surface extérieure 82 coopère avec une deuxième portion de surface interne de forme et dimension sensiblement correspondante de la deuxième cavité 20. En particulier, la deuxième portion de surface extérieure 82 se trouve dans la troisième partie 20f de la deuxième cavité 20.In the second position, the regulator member 65 interrupts the fluid communication between the corridor 104 and the gas outlet 4. The second position corresponds to the case where the valve is configured to be supplied by GP and there is no circulation of additional gas. In this case, the third portion 82 of the body of the regulator member 65 with the inlet 73 engaged at the bottom of the second cavity 20 along the longitudinal axis. In particular, the second portion 81 with at least one of the first and second outlets 74, 74' of the body is located at the bottom 86 of the second part 20e of the second cavity 20. The closing height h2 of the first outer surface portion 78 is greater than the closing height of the exit 104b of the corridor 104l. Similarly, the second outer surface portion 82 cooperates with a second inner surface portion of substantially corresponding shape and dimension of the second cavity 20. In particular, the second outer surface portion 82 is located in the third part 20f of the second cavity 20.

Comme nous pouvons le voir sur la figure 15, dans cette deuxième position de l'organe régulateur 65, la première portion de surface extérieure 78 présente une garde de fermeture SG (qui se positionne en-dessous de la sortie du couloir 104) dont la hauteur h5 est inférieure à la hauteur h4 de la deuxième portion de surface extérieure 82. La hauteur h6 de la deuxième portion 81 de l'organe régulateur 65 est inférieure à la hauteur h7 mesurée entre le fond 86 de la deuxième partie de la deuxième cavité 20 et une extrémité inférieure de la sortie 104b du couloir 104. De la sorte, aucun fluide ne peut passer entre la première portion de surface extérieure 78 et la première portion de surface interne de la deuxième cavité. La deuxième portion de surface extérieure 82 obture une portion de la deuxième cavité 20 de sorte qu'aucun fluide ne puisse passer autour de la deuxième portion de surface 82. En revanche, le passage de gaz à travers au moins l'une des première et deuxième sorties 74, 74' du passage interne 72 sera fonction de la position du cône de régulation 21 et du passage 28 de celui-ci pour laisser passer du gaz par le deuxième canal 18 comme nous le verrons ultérieurement.As we can see on the figure 15 , in this second position of the regulator member 65, the first outer surface portion 78 has a closing guard SG (which is positioned below the outlet of the corridor 104) whose height h5 is less than the height h4 of the second outer surface portion 82. The height h6 of the second portion 81 of the regulator member 65 is less than the height h7 measured between the bottom 86 of the second part of the second cavity 20 and a lower end of the outlet 104b of the corridor 104. In this way, no fluid can pass between the first outer surface portion 78 and the first inner surface portion of the second cavity. The second outer surface portion 82 closes off a portion of the second cavity 20 so that no fluid can pass around the second surface portion 82. On the other hand, the passage of gas through at least one of the first and The second outlets 74, 74' of the internal passage 72 will depend on the position of the regulating cone 21 and of the passage 28 thereof to allow gas to pass through the second channel 18 as we shall see later.

La figure 9 représente des moyens d'activation d'une électrovanne 91 de sécurité décrite ultérieurement dans la présente description. Les moyens d'activation comprennent dans cet exemple un organe d'armement 90 qui est mobile. Cet organe d'armement 90 est destiné à actionner l'électrovanne 91. L'organe d'armement 90 comprend une base 92 pourvue d'un orifice 93 d'axe G. La base 92 est définie dans un plan qui est perpendiculaire à l'axe G. Cet axe est parallèle à l'axe longitudinal en situation d'installation. La surface supérieure 13 du corps de robinet comprend un évidement 94 (représentée sur la figure 2) dans lequel est logée la base 92 pour son maintien en position. La deuxième portion 27 du cône de régulation 21 s'étend à travers l'orifice 93.The figure 9 represents means for activating a safety solenoid valve 91 described later in this description. The activation means comprise in this example a cocking member 90 which is mobile. This cocking member 90 is intended to actuate the solenoid valve 91. The cocking member 90 comprises a base 92 provided with an orifice 93 of axis G. The base 92 is defined in a plane which is perpendicular to the axis G. This axis is parallel to the longitudinal axis in the installation situation. The top surface 13 of the valve body includes a recess 94 (shown in picture 2 ) in which is housed the base 92 for holding it in position. The second portion 27 of the regulating cone 21 extends through the orifice 93.

La base 92 de l'organe d'armement 90 comprend une première surface 94 et une deuxième surface 95 opposées suivant l'axe G (ou axe longitudinal X en situation d'installation). La première surface 94 comprend des butées 96 qui s'élèvent depuis la base 92 pour délimiter la rotation de l'organe de manœuvre (la tige) entre ses deux positions. Sur la figure 9, il y a deux butées qui sont espacées l'une de l'autre suivant la circonférence de l'orifice. En particulier, l'ergot 44 se déplace sur la première surface 94 de la base 92 et entre les deux butées 96.The base 92 of the cocking member 90 comprises a first surface 94 and a second surface 95 opposite along the axis G (or longitudinal axis X in the installation situation). The first surface 94 comprises stops 96 which rise from the base 92 to limit the rotation of the actuator (the rod) between its two positions. On the figure 9 , there are two stops which are spaced apart along the circumference of the orifice. In particular, the pin 44 moves on the first surface 94 of the base 92 and between the two stops 96.

En référence à la figure 11, la deuxième surface 95 comprend une niche 97 destinée à recevoir une extrémité d'un élément de rappel 112. Ce dernier est logé dans un premier logement 98 d'axe H parallèle à l'axe longitudinal comme cela est représenté sur la figure 1. Cet élément de rappel 112 est destiné à maintenir l'organe d'armement 90 en contact avec l'ergot 44 de l'organe de manœuvre 40. L'élément de rappel 112 peut être un ressort de compression.With reference to the figure 11 , the second surface 95 comprises a recess 97 intended to receive one end of a return element 112. The latter is housed in a first housing 98 of axis H parallel to the longitudinal axis as shown on the face 1 . This return element 112 is intended to keep the arming member 90 in contact with the lug 44 of the operating member 40. The return element 112 can be a compression spring.

Le carter 50 recouvre l'organe d'armement 90 en situation d'installation.The casing 50 covers the cocking member 90 when installed.

L'organe d'armement 90 comprend également une patte 113 qui s'étend depuis la base (en particulier depuis la deuxième surface 95). La patte 113 s'étend suivant un axe parallèle à l'axe longitudinal et à l'axe G. La patte 113 comprend une extrémité libre 99. Le corps du robinet comprend un deuxième logement 100 d'axe I parallèle à l'axe longitudinal. Le deuxième logement 100 débouche d'une part sur la surface supérieure 13 et d'autre part dans un boyau 106. La patte 113 est logée dans ce deuxième logement 100. L'extrémité libre 99 est destinée à coopérer avec un pion 101 qui est agencé dans ce boyau 106. Le boyau 106 s'étend ici suivant un axe perpendiculaire à l'axe longitudinal.The cocking member 90 also includes a tab 113 which extends from the base (in particular from the second surface 95). The leg 113 extends along an axis parallel to the longitudinal axis and to the axis G. The leg 113 comprises a free end 99. The valve body comprises a second housing 100 of axis I parallel to the longitudinal axis . The second housing 100 opens on the one hand on the upper surface 13 and on the other hand in a casing 106. The tab 113 is housed in this second housing 100. The free end 99 is intended to cooperate with a pin 101 which is arranged in this casing 106. The casing 106 here extends along an axis perpendicular to the longitudinal axis.

L'organe d'armement 50 est réalisé dans un matériau polymère. Un tel matériau permet de réduire les coûts de fabrication du robinet. De manière alternative, l'organe d'armement est réalisé dans un matériau métallique. Un exemple de matériau métallique est l'aluminium ou le zamak.The cocking member 50 is made of a polymer material. Such a material makes it possible to reduce the manufacturing costs of the valve. Alternatively, the cocking member is made of a metallic material. An example of metallic material is aluminum or zamak.

Le robinet comprend une pièce mobile montée autour du cône de régulation 21 et qui comprend un crantage 102 destiné à coopérer avec un élément d'engagement mobile. Cette pièce mobile est logée au moins en partie dans le carter 50. Cet élément d'engagement mobile est en particulier au moins solidaire en rotation de l'organe de manœuvre 40. La pièce mobile peut être formée par l'organe d'armement 90. L'élément d'engagement mobile peut être formé par l'ergot 44. En particulier, la figure 10 illustre un autre mode de réalisation de l'organe d'armement 90 qui est configuré de manière à associer une position de la tige (organe de manœuvre 40) (ou du cône de régulation 21) à un débit déterminé, à maintenir cette position et de manière répétable. A cet effet, la base 92 comprend le crantage 102 coopérant avec l'ergot 44 de l'organe de manœuvre. La première surface 94 comprend une pluralité de creux 103 ou crans formés dans l'épaisseur de la base 92. Ces creux 103 s'étendent circonférentiellement de part et d'autre des butées 96. Dans ce mode de réalisation il n'y a qu'une seule butée. Les creux 103 s'étendent sur un secteur angulaire compris entre 90° et 210° ou entre 90° et 280° selon le mode de réalisation.The valve comprises a movable part mounted around the regulating cone 21 and which comprises a notch 102 intended to cooperate with a movable engagement element. This moving part is housed at least in part in the casing 50. This moving engagement element is in particular at least integral in rotation with the maneuvering member 40. The moving part can be formed by the cocking member 90 The mobile engagement element can be formed by the lug 44. In particular, the figure 10 illustrates another embodiment of the arming member 90 which is configured so as to associate a position of the rod (operating member 40) (or of the regulating cone 21) with a determined flow rate, to maintain this position and repeatably. For this purpose, the base 92 includes the notch 102 cooperating with the lug 44 of the operating member. The first surface 94 comprises a plurality of recesses 103 or notches formed in the thickness of the base 92. These recesses 103 extend circumferentially on either side of the stops 96. In this embodiment there are only only one stop. The recesses 103 extend over an angular sector comprised between 90° and 210° or between 90° and 280° depending on the embodiment.

En référence à la figure 12, le corps du robinet comprend une chambre 105 qui est destinée à loger l'électrovanne 91 de sécurité. Cette dernière permet d'empêcher la circulation du gaz dans le corps du robinet alors qu'il n'y a pas de flamme au niveau du brûleur. Plus précisément, l'électrovanne 91 empêche au gaz provenant de l'entrée de gaz 3 de circuler du premier conduit 14 à la première cavité conduit 10 où se trouve l'élément de régulation (cône de régulation 21) en absence de flamme alors que le robinet est ouvert. L'électrovanne coopère avec un système électronique ou thermoélectrique de commande relié à l'appareil de cuisson. Le système électronique ou thermoélectrique de commande comprend un thermocouple qui est agencé à proximité d'au moins un brûleur. En particulier, la chambre 105 comprend une première entrée 105a et une sortie 105b. De même, le boyau 106 (qui loge le pion 101 mobile) comprend une entrée 106a et une première sortie 106b. La première entrée 105a de la chambre 105 débouche sur une quatrième face 9. La sortie 105b est reliée à l'entrée 106a du boyau 106. La chambre 105 est sensiblement cylindrique avec un axe J qui est coaxial à celui du boyau 106. La première sortie 106b du boyau 106 est reliée à une ouverture intérieure du deuxième logement 100 dans lequel est installée la patte 113. L'électrovanne 91 est disposée dans la chambre 105 de manière à obturer sa première entrée 105a. Le boyau 106 comprend une deuxième sortie 106c qui est reliée à une deuxième entrée 14c du premier conduit 14 comme cela est visible sur la figure 4. Suivant un mode de réalisation, cette deuxième sortie 106c se trouve au-dessus du premier conduit 14 suivant l'axe longitudinal X. Avantageusement, le pion 101 comprend au moins un élément d'étanchéité 110 monté dans une gorge circonférentielle. L'élément d'étanchéité permet de fermer le boyau 66 en empêchant la circulation de gaz vers le deuxième logement 100. L'élément d'étanchéité 110 comprend ici un joint torique centré sur l'axe du pion 101.With reference to the figure 12 , the valve body comprises a chamber 105 which is intended to house the solenoid valve 91 of safety. The latter makes it possible to prevent the circulation of gas in the body of the valve when there is no flame at the level of the burner. More precisely, the solenoid valve 91 prevents the gas coming from the gas inlet 3 from flowing from the first conduit 14 to the first cavity conduit 10 where the regulating element is located (regulating cone 21) in the absence of flame whereas the tap is open. The solenoid valve cooperates with an electronic or thermoelectric control system connected to the cooking appliance. The electronic or thermoelectric control system comprises a thermocouple which is arranged close to at least one burner. In particular, chamber 105 includes a first inlet 105a and an outlet 105b. Similarly, the casing 106 (which houses the mobile pin 101) comprises an inlet 106a and a first outlet 106b. The first inlet 105a of the chamber 105 leads to a fourth face 9. The outlet 105b is connected to the inlet 106a of the casing 106. The chamber 105 is substantially cylindrical with an axis J which is coaxial with that of the casing 106. The first Outlet 106b of hose 106 is connected to an internal opening of second housing 100 in which tab 113 is installed. Solenoid valve 91 is placed in chamber 105 so as to close off its first inlet 105a. The hose 106 includes a second outlet 106c which is connected to a second inlet 14c of the first conduit 14 as is visible on the figure 4 . According to one embodiment, this second outlet 106c is located above the first duct 14 along the longitudinal axis X. Advantageously, the pin 101 comprises at least one sealing element 110 mounted in a circumferential groove. The sealing element makes it possible to close the hose 66 by preventing the circulation of gas towards the second housing 100. The sealing element 110 here comprises an O-ring centered on the axis of the pin 101.

En référence à la figure 13, l'électrovanne 91 comprend typiquement au moins un électroaimant (non représenté), un obturateur 91a et un connecteur mâle 91c. L'électroaimant est contenu dans un boîtier 107 cylindrique d'axe coaxial à l'axe J (en situation d'installation) à section circulaire. Le boîtier 107 comprend un diamètre sensiblement égal ou inférieur à celui de la chambre 105. L'obturateur se déplace dans la chambre de manière à libérer ou obturer la sortie de la chambre. L'obturateur 91a est mobile par rapport au boîtier 107. Celui-ci comprend une semelle 109 en forme de disque qui est définie dans un plan perpendiculaire à l'axe du boîtier. Une tige 91d s'étend depuis la semelle 109 et en partie à l'intérieur du boitier où elle se déplace en translation suivant l'axe J. La semelle porte un élément d'étanchéité 111 pour garantir la fermeture hermétique de la chambre 105 lorsque l'électrovanne 91 est dans sa position de fermeture. La section de la sortie de la chambre 105 est supérieure à celle de l'entrée du boyau 106.With reference to the figure 13 , the solenoid valve 91 typically comprises at least one electromagnet (not shown), a shutter 91a and a male connector 91c. The electromagnet is contained in a cylindrical casing 107 with an axis coaxial with the axis J (in the installation situation) with a circular section. The housing 107 comprises a diameter substantially equal to or less than that of the chamber 105. The shutter moves in the chamber so as to release or block the exit from the chamber. The shutter 91a is movable relative to the housing 107. The latter comprises a sole 109 in the form of a disc which is defined in a plane perpendicular to the axis of the housing. A rod 91d extends from the sole 109 and partly inside the case where it moves in translation along the axis J. The sole carries a sealing element 111 to guarantee the hermetic closure of the chamber 105 when the solenoid valve 91 is in its closed position. The section of the outlet of the chamber 105 is greater than that of the inlet of the casing 106.

Par ailleurs, en référence aux figures 4 et 12, le corps comprend un deuxième conduit 108 avec une entrée et une sortie 108b. L'entrée débouche dans l'entrée de gaz 3 tandis que la sortie 108b débouche dans la chambre 105. Une deuxième entrée 105c de la chambre est reliée à la sortie 108b du deuxième conduit 108.Moreover, with reference to figure 4 and 12 , the body comprises a second duct 108 with an inlet and an outlet 108b. The inlet opens into the gas inlet 3 while the outlet 108b opens into the chamber 105. A second inlet 105c of the chamber is connected to the outlet 108b of the second conduit 108.

Le corps présente une forme générale de parallélépipède rectangle avec une première portion et une deuxième portion. Dans la première portion est formée la chambre 105 de l'électrovanne de sécurité tandis que dans la deuxième portion est formée au moins l'entrée de gaz 3. La sortie de gaz 4 est également prévue dans la deuxième portion. Dans ce cas de figure l'axe de l'entrée de gaz et l'axe J de la chambre 105 sont sensiblement parallèles.The body has the general shape of a rectangular parallelepiped with a first portion and a second portion. In the first portion is formed the chamber 105 of the safety solenoid valve while in the second portion is formed at least the gas inlet 3. The gas outlet 4 is also provided in the second portion. In this case, the axis of the gas inlet and the axis J of the chamber 105 are substantially parallel.

Suivant une alternative, le corps présente une section en forme de V. Dans ce cas, les axes de l'entrée de gaz et de la chambre 105 sont inclinés l'un par rapport à l'autre en formant un angle obtus. Une telle configuration permet un gain de matière dans la réalisation du corps du robinet.According to an alternative, the body has a V-shaped section. In this case, the axes of the gas inlet and of the chamber 105 are inclined with respect to each other forming an obtuse angle. Such a configuration allows a saving of material in the realization of the valve body.

Nous allons maintenant présenter le fonctionnement d'un robinet d'alimentation en référence aux figures 14 à 22 qui sont très schématiques.We will now present the operation of a supply tap with reference to the figures 14 to 22 which are very schematic.

Sur les figures 14 et 15, le robinet d'alimentation de gaz est fermé et l'organe régulateur 65 occupe sa deuxième position pour que le robinet fonctionne avec du GP. Dans ce cas, le cône de régulation 21 occupe la position minimale dans laquelle il n'y a aucun gaz qui circule vers la sortie de gaz. Pour cela, le passage 28 est détourné des première, deuxième et troisième sorties 16a, 16b, 16c de la première cavité 10. La surface externe 25 pleine du cône de régulation 21 obture les première, deuxième et troisième sorties 16a, 16b, 16c. L'organe régulateur 65 est vissé à fond dans la deuxième cavité 20. L'organe régulateur 65 obture la sortie du couloir 104.On the figures 14 and 15 , the gas supply valve is closed and the regulating member 65 occupies its second position so that the valve operates with GP. In this case, the regulation cone 21 occupies the minimum position in which there is no gas flowing towards the gas outlet. For this, the passage 28 is diverted from the first, second and third outlets 16a, 16b, 16c of the first cavity 10. The solid outer surface 25 of the regulating cone 21 closes off the first, second and third outlets 16a, 16b, 16c. The regulator member 65 is screwed fully into the second cavity 20. The regulator member 65 closes off the outlet of the corridor 104.

Sur la figure 16, le robinet 1 est ouvert et l'organe régulateur 65 occupe sa deuxième position pour que le robinet fonctionne avec du GP. Sur cette figure, le cône de régulation 21 occupe sa position maximale où du gaz circule dans le corps du robinet de l'entrée de gaz à la sortie de gaz. Cette position du cône de régulation 21 correspond à un angle d'ouverture d'environ 90°. Pour ouvrir le robinet 1, l'organe de manœuvre 40 a translaté et pivoté suivant l'axe longitudinal ce qui a poussé la patte 113 de l'organe d'armement au fond de son logement 100. L'extrémité libre 99 de la patte 113 a entraîné le pion 101 en translation (suivant l'axe J) pour actionner l'électroaimant et désengager l'obturateur 91a de l'entrée 106a du boyau 106. Le gaz peut circuler jusque dans la première cavité 10, en passant par le premier conduit 14, où se trouve le cône de régulation 21. Le passage 28 de ce dernier et notamment la partie la plus élargie 28a se trouve en regard du premier canal 17 et du couloir 104. Dans le cas où le robinet est équipé d'une pièce mobile avec un crantage 102 (organe d'armement 90 par exemple), la tige a pivoté jusqu'à ce que l'ergot 44 soit logé dans un deuxième creux correspondant à la position de sensiblement 90° de la butée. Cependant, le gaz ne circule que dans le premier canal 17 et en plein débit puisque l'organe régulateur 65 obture la sortie 104b du couloir 104. Il n'y a aucune portion du passage 28 en regard du deuxième canal 18.On the figure 16 , the valve 1 is open and the regulating member 65 occupies its second position so that the valve operates with GP. In this figure, the regulating cone 21 occupies its maximum position where gas circulates in the valve body from the gas inlet to the gas outlet. This position of the regulating cone 21 corresponds to an opening angle of approximately 90°. To open the valve 1, the operating member 40 has translated and pivoted along the longitudinal axis which has pushed the lug 113 of the cocking member to the bottom of its housing 100. The free end 99 of the lug 113 has driven pin 101 in translation (along axis J) to actuate the electromagnet and disengage shutter 91a of the inlet 106a of the hose 106. The gas can flow into the first cavity 10, passing through the first duct 14, where the regulating cone 21 is located. The passage 28 of the latter and in particular the widest part 28a is located opposite the first channel 17 and the corridor 104. In the case where the valve is equipped with a moving part with a notch 102 (cocking member 90 for example), the rod has pivoted until the lug 44 is housed in a second hollow corresponding to the substantially 90° position of the stop. However, the gas only circulates in the first channel 17 and at full flow since the regulator member 65 closes off the outlet 104b of the corridor 104. There is no portion of the passage 28 facing the second channel 18.

Sur la figure 17, le robinet est ouvert et l'organe régulateur 65 occupe sa deuxième position pour que le robinet fonctionne avec du GP. Le cône de régulation 21 occupe une première position intermédiaire où du gaz circule dans le corps du robinet de l'entrée de gaz à la sortie de gaz. Cette position du cône de régulation 21 correspond à un angle d'ouverture compris entre 120° et 260° ou entre 120° et 200° et l'ergot 44 repose dans un troisième creux correspondant. Dans cette position, la partie la plus élargie 28a est en regard de l'entrée du deuxième canal 18. Le deuxième canal 18 permet la circulation d'un débit réduit de gaz vers la sortie 4 et en passant par le passage interne 72, puis dans le troisième canal 67. Le passage interne 72 est en communication fluidique avec le troisième canal 67. Il n'y a pas de gaz circulant autour de deuxième portion de surface extérieure 82 (et vers le troisième canal 67) puisque celle-ci est en contact avec la portion de surface interne correspondante de la deuxième cavité 20. De même, une première section du passage 28 se trouve en regard en regard de la première sortie 16a de la première cavité 10. De la sorte un certain débit de gaz circule dans le premier canal 17 vers la sortie de gaz 4. Une deuxième section du passage 28 se trouve en regard de la sortie 16c du couloir 104 mais la sortie 104b du couloir 104 est obturée par l'organe régulateur 65. Le débit de gaz circulant dans le premier canal 17 et dans le deuxième canal 18 dans cette position est inférieur au débit de gaz circulant dans le premier canal de la figure 16.On the figure 17 , the valve is open and the regulating member 65 occupies its second position so that the valve operates with GP. The regulating cone 21 occupies a first intermediate position where gas circulates in the valve body from the gas inlet to the gas outlet. This position of the regulating cone 21 corresponds to an opening angle comprised between 120° and 260° or between 120° and 200° and the lug 44 rests in a corresponding third recess. In this position, the widest part 28a is opposite the inlet of the second channel 18. The second channel 18 allows the circulation of a reduced flow of gas towards the outlet 4 and passing through the internal passage 72, then in the third channel 67. The internal passage 72 is in fluid communication with the third channel 67. There is no gas circulating around the second portion of outer surface 82 (and towards the third channel 67) since the latter is in contact with the corresponding internal surface portion of the second cavity 20. Similarly, a first section of the passage 28 is opposite facing the first outlet 16a of the first cavity 10. In this way a certain flow of gas circulates in the first channel 17 towards the gas outlet 4. A second section of the passage 28 is opposite the outlet 16c of the corridor 104 but the outlet 104b of the corridor 104 is closed off by the regulator member 65. The flow of gas circulating in the first channel 17 and in s the second channel 18 in this position is lower than the flow rate of gas circulating in the first channel of the figure 16 .

La figure 18 illustre le robinet ouvert et l'organe régulateur 65 dans sa deuxième position pour que le robinet fonctionne avec du GP. Le cône de régulation 21 occupe une deuxième position intermédiaire de débit intermédiaire où du gaz circule dans le corps du robinet de l'entrée de gaz à la sortie de gaz. Le cône de régulation 21 se trouve dans une position dont l'angle d'ouverture est de l'ordre de 280° ou 210°. L'ergot 44 repose dans un quatrième creux correspondant depuis la butée de fermeture. Une troisième section (au niveau de la partie la plus réduite du passage 28) se trouve en regard de la sortie 16b qui débouche dans le deuxième canal 18. De la sorte, le gaz circule dans le deuxième canal 18, dans le passage interne 72, puis dans le troisième canal 67. La surface externe 25 pleine du cône de régulation obture les sorties 16a et 16c qui débouchent respectivement dans le premier canal 17 et dans le couloir 104. Le débit de gaz circulant uniquement dans le premier canal 18 dans cette position est inférieur au débit de gaz circulant dans les premier et deuxième canaux 17, 18 de la figure 17.The figure 18 illustrates the valve open and the regulating member 65 in its second position so that the valve operates with GP. The regulating cone 21 occupies a second intermediate position of intermediate flow where gas flows in the valve body from the gas inlet to the gas outlet. The regulating cone 21 is in a position whose opening angle is of the order of 280° or 210°. The lug 44 rests in a corresponding fourth recess from the closing stop. A third section (at the level of the smallest part of the passage 28) is opposite the outlet 16b which opens into the second channel 18. In this way, the gas circulates in the second channel 18, in the internal passage 72, then in the third channel 67. The solid external surface 25 of the regulation cone closes the outlets 16a and 16c which open respectively into the first channel 17 and into the corridor 104. The flow of gas circulating only in the first channel 18 in this position is lower than the flow rate of gas circulating in the first and second channels 17, 18 of the figure 17 .

Sur la figure 19, le robinet est fermé et l'organe régulateur 65 occupe sa première position pour que le robinet fonctionne avec du GN. Le cône de régulation 21 occupe la position minimale dans laquelle il n'y a aucun gaz qui circule vers la sortie de gaz. Le passage 28 est détourné des première, deuxième et troisième sorties 16a, 16b, 16c de la première cavité 10. La surface externe 25 pleine du cône de régulation obture les première, deuxième et troisième sorties. Comme nous le verrons dans les figures suivantes représentant le robinet ouvert, l'organe régulateur 65 libère une section supplémentaire dans la deuxième cavité 20 pour le réglage du débit réduit en GN qui circule dans le deuxième canal. En particulier, l'organe régulateur 65 libère aussi la sortie 104b pour permettre une circulation d'un débit additionnel pour le GN et dans une position de débit « plein débit » et de « débit intermédiaire » du cône de régulation.On the figure 19 , the tap is closed and the regulating member 65 occupies its first position so that the tap operates with NG. The regulating cone 21 occupies the minimum position in which there is no gas flowing towards the gas outlet. The passage 28 is diverted from the first, second and third outlets 16a, 16b, 16c of the first cavity 10. The solid outer surface 25 of the regulating cone closes off the first, second and third outlets. As we will see in the following figures representing the valve open, the regulating member 65 frees up an additional section in the second cavity 20 for adjusting the reduced GN flow rate which circulates in the second channel. In particular, the regulator member 65 also releases the outlet 104b to allow circulation of an additional flow for the NG and in a "full flow" and "intermediate flow" flow position of the regulation cone.

Sur la figure 20, le robinet est ouvert et l'organe régulateur 65 occupe sa première position pour que le robinet fonctionne avec du GN. Le cône de régulation 21 occupe la position maximale dans laquelle le gaz circule de l'entrée à la sortie de gaz. L'ergot 44 est logé dans le deuxième creux correspondant à la position de sensiblement 90° de la butée de fermeture. Le passage 28 et notamment sa partie la plus élargie 28a se trouve en regard des premières et deuxième sorties de la première cavité 10. Le gaz qui est arrivé dans la première cavité 10 traverse le cône de régulation 21 et circule dans le premier canal 17. Le gaz circule également dans le couloir 104 puis est évacué vers le troisième canal 67. En effet, la première portion de surface externe 78 se trouve au-dessus de l'entrée 67a du troisième canal 67 et axialement à l'extérieur de extrémité inférieure de la sortie du couloir 104 suivant l'axe longitudinal. En particulier, l'organe régulateur 65 augmente la section de l'entrée du troisième canal 67 et de la sortie du couloir 104 lequel apporte le débit additionnel pour le GN. Le débit de gaz GN circulant dans le premier canal 17 et dans le couloir 104 dans cette position est supérieur au débit GP tel qu'illustré sur la figure 16. En revanche, la puissance du brûleur est sensiblement identique à la puissance délivrée par le robinet au niveau de la sortie de gaz illustrée sur la figure 16.On the figure 20 , the tap is open and the regulating member 65 occupies its first position so that the tap operates with NG. The regulating cone 21 occupies the maximum position in which the gas flows from the gas inlet to the gas outlet. The lug 44 is housed in the second recess corresponding to the substantially 90° position of the closure stop. The passage 28 and in particular its widest part 28a is opposite the first and second outlets of the first cavity 10. The gas which has arrived in the first cavity 10 passes through the regulation cone 21 and circulates in the first channel 17. The gas also circulates in the corridor 104 then is evacuated towards the third channel 67. Indeed, the first external surface portion 78 is located above the inlet 67a of the third channel 67 and axially outside of the lower end from the exit of the corridor 104 along the longitudinal axis. In particular, the regulating member 65 increases the section of the inlet of the third channel 67 and of the outlet of the corridor 104 which provides the additional flow for the GN. The flow of GN gas circulating in the first channel 17 and in the corridor 104 in this position is greater than the GP flow as illustrated in the figure 16 . On the other hand, the power of the burner is substantially identical to the power delivered by the tap at the level of the gas outlet illustrated on the figure 16 .

Sur la figure 21, le robinet est ouvert et l'organe régulateur 65 occupe sa première position pour que le robinet fonctionne avec du GN. Le cône de régulation 21 occupe une première position intermédiaire où du gaz circule dans le corps du robinet de l'entrée de gaz à la sortie de gaz. Le cône de régulation 21 est dans la position correspondant à un angle d'ouverture compris entre 120° et 260° ou entre 120° et 200°0. L'ergot 44 repose dans le troisième creux correspondant. La partie la plus élargie 28a est en regard de l'entrée du deuxième canal 18. Le deuxième canal 18 permet la circulation d'un débit réduit de gaz vers la sortie 4 et en passant à la fois, par le passage interne 72 et autour de l'organe régulateur 65 (de la troisième partie à la deuxième partie de la deuxième cavité 20), puis dans le troisième canal 67. En effet, étant donné, que le diamètre D2 de la deuxième portion du corps qui comprend la ou les sortie(s) 74 est inférieur au diamètre D22 de la deuxième partie de la cavité et que la deuxième portion de surface extérieure 82 est à l'intérieur de la deuxième partie 20e de cavité 20, le gaz provenant du deuxième canal 18 circule également autour de la deuxième portion 81 de l'organe régulateur 65. De même, la première section du passage 28 se trouve en regard de la première sortie 16a de la première cavité 10 pour qu'un certain débit de gaz circule dans le premier canal 17 vers la sortie de gaz 4. La deuxième section du passage 28 se trouve également en regard de la sortie 16c du couloir 104 pour qu'un certain débit de gaz passe dans la deuxième cavité 20 et en particulier autour de la deuxième portion 81 de l'organe régulateur 65 vers la sortie de gaz 4. Il y a bien un débit additionnel pour utilisation en GN. Le débit de gaz circulant dans le premier canal 17, le deuxième canal 18 et couloir 104 dans cette position est inférieur au débit de gaz circulant dans les premier et deuxième canaux sur la figure 20. Ce débit de gaz GN en sortie du robinet est supérieur à celui en sortie 4 de la figure 17. La puissance du brûleur est sensiblement identique à celle délivrée par le robinet au niveau de la sortie de gaz illustrée sur la figure 17.On the figure 21 , the tap is open and the regulating member 65 occupies its first position so that the tap operates with NG. The regulation cone 21 occupies a first intermediate position where gas flows through the valve body from the gas inlet to the gas outlet. The regulating cone 21 is in the position corresponding to an opening angle of between 120° and 260° or between 120° and 200°0. The lug 44 rests in the corresponding third recess. The widest part 28a is opposite the inlet of the second channel 18. The second channel 18 allows the circulation of a reduced flow of gas towards the outlet 4 and passing both through the internal passage 72 and around of the regulating member 65 (from the third part to the second part of the second cavity 20), then in the third channel 67. Indeed, given that the diameter D2 of the second portion of the body which includes the outlet(s) 74 is less than the diameter D22 of the second part of the cavity and the second outer surface portion 82 is inside the second part 20 of the cavity 20, the gas coming from the second channel 18 also circulates around of the second portion 81 of the regulator member 65. Similarly, the first section of the passage 28 is opposite the first outlet 16a of the first cavity 10 so that a certain flow of gas circulates in the first channel 17 towards the gas outlet 4. The second section of the passage 28 is tro uve also opposite the outlet 16c of the corridor 104 so that a certain gas flow passes into the second cavity 20 and in particular around the second portion 81 of the regulator member 65 towards the gas outlet 4. There is additional flow for use in GN. The gas flow rate circulating in the first channel 17, the second channel 18 and corridor 104 in this position is less than the gas flow rate circulating in the first and second channels on the figure 20 . This flow of GN gas at the valve outlet is greater than that at outlet 4 of the figure 17 . The power of the burner is substantially identical to that delivered by the valve at the level of the gas outlet illustrated on the figure 17 .

Sur la figure 22, le robinet est ouvert et l'organe régulateur 65 dans sa première position pour que le robinet fonctionne avec du GN. Le cône de régulation 21 occupe une deuxième position intermédiaire de débit intermédiaire où du gaz circule dans le corps du robinet de l'entrée de gaz à la sortie de gaz. Le cône de régulation 21 se trouve dans une position dont l'angle d'ouverture est de l'ordre de 280° ou 210°. L'ergot 44 repose dans le quatrième creux correspondant depuis la butée de fermeture. La troisième section (au niveau de la partie la plus réduite du passage 28) se trouve en regard de la sortie 16b qui débouche dans le deuxième canal. De la sorte, le gaz circule dans le deuxième canal 18, puis dans le troisième canal 67. En particulier, le gaz circule dans le passage interne 72 et autour de la deuxième portion 81 de l'organe régulateur 65. La surface externe 25 pleine du cône de régulation obture les sorties 16a et 16c qui débouchent respectivement dans le premier canal 17 et dans le couloir 104. Le débit de gaz circulant uniquement dans le premier canal 18 dans cette position est inférieur au débit de gaz circulant dans les premier et deuxième canaux 17, 18 et dans le couloir 104 de la figure 21. Ce débit de gaz GN en sortie du robinet est supérieur à celui en sortie de gaz 4 sur la figure 18. La puissance du brûleur est sensiblement identique à celle délivrée par le robinet au niveau de la sortie de gaz 4 illustrée sur la figure 18.On the figure 22 , the tap is open and the regulating member 65 in its first position so that the tap operates with NG. The regulating cone 21 occupies a second intermediate position of intermediate flow where gas flows in the valve body from the gas inlet to the gas outlet. The regulating cone 21 is in a position whose opening angle is of the order of 280° or 210°. The lug 44 rests in the corresponding fourth recess from the closing stop. The third section (at the level of the smallest part of the passage 28) is opposite the outlet 16b which opens into the second channel. In this way, the gas circulates in the second channel 18, then in the third channel 67. In particular, the gas circulates in the internal passage 72 and around the second portion 81 of the regulator member 65. The solid external surface 25 of the regulation cone closes the outlets 16a and 16c which respectively open into the first channel 17 and into the corridor 104. The gas flow rate circulating only in the first channel 18 in this position is lower than the gas flow rate circulating in the first and second channels 17, 18 and in corridor 104 of the figure 21 . This flow of GN gas at the tap outlet is greater than that at the gas outlet 4 on the figure 18 . The power of the burner is substantially identical to that delivered by the valve at the level of the gas outlet 4 illustrated in the figure 18 .
