Abstract

The pressure-driven motor has a main rotor (1) with pistons and connecting rods (3,4) working in one or more rings of cylinder. The protruding free ends of the rods pivot on an auxiliary rotor (6) turning on an axis eccentric to that of the main one. The rotors are coupled together, and air or fluid is delivered to the cylinders by a distributor. The main rotor is fixed to a driving shaft (2). The rotors are coupled by components giving instantaneous angular velocity and driving torque of the auxiliary one equal to those of the main one.

Description

L'invention concerne un moteur qui utilise un fluide opérateur pour produire, à travers l'action de pistons appartenant à des cylindres correspondants pratiqués dans un ou plusieurs rotors solidaires d'un même arbre, le mouvement de rotation de l'arbre lui-même.The invention relates to an engine which uses an operating fluid to produce, through the action of pistons belonging to corresponding cylinders formed in one or more rotors integral with the same shaft, the rotational movement of the shaft itself .

On conna t des moteurs et des pompes à fluide, comprenant un rotor logé de manière excentrique dans une capsule fixe et pourvue d'aubes radiales oscillantes qui sont destinées à délimiter, avec la paroi interne de la capsule, des chambres de volume variable dans lesquelles s'effectue l'expansion du fluide.
En particulier, on conna t des moteurs rotatif à capsulismes, fonctionnant spécialement à air comprimé, mais l'utilisation de ces moteurs est limitée à des puissances non élevées et/ou pour des couples de moment élevé, mais de brève durée; les limitations sont dues, en outre, au faible rendement lié aux pertes mécaniques, de chaleur et de fluide.
On conna t également des moteurs en étoile à air comprimé avec des cylindres radiaux dont les pistons sont reliés à l'arbre manivelle, séparément ou opposés par paires; mais ces moteurs sont lourds et présentent un encombrement considérable.Fluid motors and pumps are known, comprising a rotor eccentrically housed in a fixed capsule and provided with oscillating radial vanes which are intended to delimit, with the internal wall of the capsule, chambers of variable volume in which fluid expansion takes place.
In particular, capsulism rotary motors are known, operating especially with compressed air, but the use of these motors is limited to non-high powers and / or for couples of high moment, but of short duration; the limitations are due, in addition, to the low efficiency linked to mechanical, heat and fluid losses.
Also known are compressed air star motors with radial cylinders, the pistons of which are connected to the crankshaft, separately or in pairs; but these engines are heavy and have a considerable bulk.

En particulier, le document GB-A-20609 décrit un moteur à combustion interne dans lequel un tambour avec une couronne de cylindres est monté fou sur le coude d'un arbre manivelle qui est fixe, de manière à tourner excentriquement par rapport à l'axe dudit arbre, et dans lequel un volant, sur lequel sont articulées les pieds des bielles qui sortent des cylindres du tambour précité, tourne fou sur le mem̂e arbre fixe sous l'action de l'entrain̂ement transmis par le tambour au moyen de plusieurs joints à genou avec charnière; ledit arbre fixe et le coude sont creux, pour permettre, à une extrémité, l'alimentation du combustible et, à l'autre extrémité, l'échappement des gaz brul̂és, à travers des orifices correspondants d'admission et d'échappement prévus dans les cylindres.
Mais ce type de moteur nécessite l'utilisation du mouvement du volant au moyen d'une courroie; il utilise des moyens de liaison du tambour au volant qui forment une chain̂e cinématique ouverte qui ne permet pas l'inversion du mouvement en invertissant le flux du fluide opérateur, et il impose en outre au volant une vitesse angulaire instantanée non constante de sorte que le moteur ne s'avère pas correctement equilibré; par ailleurs, il nécessite la perforation longitudinale de l'arbre fixe de support.In particular, document GB-A-20609 describes an internal combustion engine in which a drum with a ring of cylinders is mounted idly on the elbow of a crank shaft which is fixed, so as to rotate eccentrically with respect to the axis of said shaft, and in which a flywheel, on which are articulated the feet of the connecting rods which exit from the cylinders of the aforementioned drum, turns mad on the same fixed shaft under the action of the drive transmitted by the drum by means of several seals kneeling with hinge; said fixed shaft and the elbow are hollow, to allow, at one end, the fuel supply and, at the other end, the exhaust of burnt gases, through corresponding orifices of intake and exhaust provided in the cylinders.
But this type of engine requires the use of the movement of the steering wheel by means of a belt; it uses means for connecting the drum to the steering wheel which form an open kinematic chain which does not allow the reversal of the movement by inverting the flow of the operating fluid, and it furthermore imposes on the steering wheel an instantaneous angular speed which is not constant so that the engine is not properly balanced; moreover, it requires the longitudinal perforation of the fixed support shaft.

On connaît également, d'après le document BE 371.137, une machine rotative a réaction qui comprend deux couronnes exentriques, interagissant par l'intermédiaire d'un ensemble de cylindres et pistons, dont une, celle interne (3), supporte les cylindres (5) et la chambre de distribution du fluide opérateur, alors que l'autre, celle externe, supporte les bielles des pistons.
Mais cette machine rotative connue prévoit que l'alimentation de la chambre de distribution s'effectue au moyen d'un orifice prévue à l'intérieur de la couronne interne (3), ce qui entraîne une plus complexité de construction; impose le respect de tolérance d'étalonnage de l'orifice trés strictes, pour mantenir le déséquilibre dynamique de ladite couronne dans les limites acceptables; et reduit la capacité de réponse de la couronne interne (3) aux caractéristiques de contrainte de flexion et de torsion.Also known, from document BE 371.137, is a rotary reaction machine which comprises two eccentric rings, interacting by means of a set of cylinders and pistons, one of which, the internal one (3), supports the cylinders ( 5) and the operator fluid distribution chamber, while the other, the external one, supports the piston rods.
However, this known rotary machine provides that the supply to the distribution chamber is effected by means of an orifice provided inside the internal ring (3), which leads to more construction complexity; requires compliance with very strict orifice calibration tolerance, to maintain the dynamic imbalance of said crown within acceptable limits; and reduces the response capacity of the internal crown (3) to the characteristics of bending and torsional stress.

La présente invention a pour but d'éliminer les inconvénients précités.
Ce résultat a été atteint conformément à l'invention en proponant un moteur à fluide avec mouvement de rotation comprenant au moins un rotor principal avec au moins une couronne de cylindres avec les pistons et bielles correspondants qui font saillie de la périphérie du rotor, un rotor auxiliaire, roulant autour d'un axe excentrique par rapport au rotor principal et sur lequel sont articulés les pieds des dites bielles, moyens de distribution du fluide aux cylindres du rotor principal, dans lequel le roteur principal est solidaire d'un arbre roulant, moteur et dans lequel les moyens de liaison des rotors sont des jumelles identiques et pareillement orientées, avec deux pivots, l'un associé au rotor principal et l'autre au rotor auxiliaire et qui possèdent une distance d'entraxe, égale à l'excentricité du rotor auxiliaire par rapport au rotor principal et de manière de rouler en concordance, à le mem̂e vitesse angulaire instantaneé et avec un mem̂e couple par rapport au rotor principal.The present invention aims to eliminate the aforementioned drawbacks.
This result was achieved in accordance with the invention by proposing a fluid motor with rotational movement comprising at least one main rotor with at least one ring of cylinders with the corresponding pistons and connecting rods which project from the periphery of the rotor, an auxiliary rotor, rolling around an axis eccentric relative to the main rotor and on which the feet of said connecting rods, means for distributing the fluid to the cylinders of the main rotor, are articulated, in which the main rotator is integral with a rolling shaft, motor and in which the means for connecting the rotors are identical and similarly oriented binoculars, with two pivots, one associated with the main rotor and the other with the auxiliary rotor and which have a center distance, equal to the eccentricity of the auxiliary rotor relative to the main rotor and so as to roll in concordance with the same instantaneous angular speed and with the same torque with respect to the main rotor.

Avantageusement, conformément à l'invention, il est prévu de varier à volonté la course des pistons en la rendant indépendante de l'excentricité du rotor auxiliaire, en reliant les pieds de bielle à l'articulation qui relie les deux rotors, au moyen d'une manivelle intermédiaire.Advantageously, in accordance with the invention, it is planned to vary the stroke of the pistons at will by making it independent of the eccentricity of the auxiliary rotor, by connecting the connecting rod feet to the articulation which connects the two rotors, by means of 'an intermediate crank.

Les avantages obtenus grâce à l'invention consistent essentiellement dans le fait qu'un moteur selon l'invention alimenté par air comprimé possède une valeur de couple plus constante par rapport aux moteurs connus; qu'il présente une consommation spécifique inférieure par rapport aux moteurs connus à capsulismes et à cylindres radiaux; qu'il a un encombrement et un poids réduits et inférieurs à ceux des moteurs connus à ce jour; qu'il est de par lui-même très bien équilibré et de ce fait ne nécessite aucun contrepoids; qu'il est de construction simple et de très grande fiabilité.The advantages obtained by virtue of the invention essentially consist in the fact that an engine according to the invention supplied by compressed air has a more constant torque value compared to known engines; that he presents a lower specific consumption compared to known engines with capsulisms and radial cylinders; that it has a reduced size and weight and is lower than that of the motors known to date; that it is by itself very well balanced and therefore requires no counterweight; that it is simple in construction and very reliable.

Ces avantages et caractéristiques ainsi que d'autres seront plus et mieux compris de chaque homme du métier à la lumière de la description qui va suivre et à l'aide des dessins annexés donnés à titre d'exemplification pratique de l'invention, mais à ne pas considérer dans le sens limitatif; dessins sur lesquels: la FIG. 1 représente schématiquement une vue tranversale d'un moteur à fluide avec une couronne de quatre cylindres conformément à l'invention, suivant une première forme de réalisation; la FIG. 2 représente la vue en coupe suivant la ligne A-A de la Fig. 1; la FIG. 3 représente la vue transversale détaillée de la distribution pour le moteur de la Fig. 1; la FIG. 4 représente la vue transversale d'une variante du moteur de la Fig. 1; la FIG. 5 représente la vue en coupe suivant la ligne B-B de la Fig. 4.These advantages and characteristics as well as others will be more and better understood by each person skilled in the art in the light of the description which follows and with the aid of the appended drawings given by way of practical example of the invention, but to do not consider in the limiting sense; drawings in which: FIG. 1 schematically represents a transverse view of a fluid engine with a crown of four cylinders according to the invention, according to a first embodiment; FIG. 2 shows the sectional view along line A-A of FIG. 1; FIG. 3 shows the detailed transverse view of the distribution for the motor of FIG. 1; FIG. 4 shows the transverse view of a variant of the engine of FIG. 1; FIG. 5 shows the sectional view along line B-B of FIG. 4.

Réduit à sa structure essentielle et en référence aux Fig. 1 à 3 des dessins annexés, un moteur à fluide, en particulier à air comprimé, avec mouvement de rotation, conformément à l'invention, dans une forme de réalisation simplifiée, comprend:

  • un premier rotor 1 ou rotor principal, sous la forme d'un parallélépipède avec contour en octagone irrégulier, qui contient quatre chambres cylindriques 11, c'est-à-dire des cylindres, égales, coplanaires et avec le fond ouvert en correspondance des faces latérales de l'octagone; l'axe longitudinal "x" de chaque cylindre 11, qui est perpendiculaire audit fond, coupe un rayon correspondant "r" du rotor 1, qui est perpendiculaire audit axe "x", à égale distance "e" de l'axe de rotation "Z" du rotor 1 et de manière à ce que l'axe "x" de chaque cylindre 11 ne soit coplanaire audit axe "Z". Chaque cylindre 11 loge et guide un piston correspondant 3 avec la bielle 4 respective qui fait saillie du rotor 1 à travers le fond du cylindre 11.
    Ledit rotor 1 est engagé solidaire sur l'arbre de rotation 2 qui, à son tour, est monté sur coussinets 20 d'un bâti 5;
  • un deuxième rotor 6 ou rotor auxiliaire, en forme de capsule cylindrique, entourant le rotor principal 1 et monté sur coussinets 61 du bâti 5 de manière à tourner autour de son propre axe "z" qui est parallèle à celui "Z" de rotation du rotor principal 1 et dont l'excentricité "E" est égale à ladite distance "e". Ledit rotor auxiliaire 6 est relié au rotor principal 1 au moyen de quatre jumelles 7 coplanaires et orientées de même manière, qui tournent autour de deux axes correspondants "z1 et z6" parallèles entre eux et à l'axe "Z" du rotor principal 1 et dont la distance réciproque est égale à ladite excentricité "E".
    Le pied 40 de chaque bielle 4 du rotor principal 1 est articulé audit rotor auxiliaire 6 au moyen d'une cheville 63 dont l'axe "z4" est parallèle à celui "Z" de rotation du rotor principal 1;
  • des moyens 8 de distribution de l'air comprimé aux cylindres 11 du rotor principal 1, comprenant un corps cylindrique 80 fixé axialement sur le bâti 5 et dont le corps est pourvu de deux conduits 81 et 82, l'un 81 pour l'introduction de l'air comprimé dans les cylindres 11 à travers une ouverture latérale correspondante 12 des cylindres et l'autre 82 pour l'évacuation de l'air épuisé des cylindres 11 à travers la même ouverture 12 après une rotation angulaire du rotor principal 1 nécessaire pour conclure la phase active.
Reduced to its essential structure and with reference to Figs. 1 to 3 of the accompanying drawings, a fluid motor, in particular compressed air, with rotational movement, according to the invention, in a simplified embodiment, comprises:
  • a first rotor 1 or main rotor, in the form of a parallelepiped with an irregular octagon contour, which contains four cylindrical chambers 11, that is to say cylinders, equal, coplanar and with the open bottom corresponding to the faces sides of the octagon; the longitudinal axis "x" of each cylinder 11, which is perpendicular to said bottom, cuts a corresponding radius "r" of the rotor 1, which is perpendicular to said axis "x", equidistant from the axis of rotation "Z" of the rotor 1 and in such a way that the axis "x" of each cylinder 11 is not coplanar with said axis "Z". Each cylinder 11 houses and guides a corresponding piston 3 with the respective connecting rod 4 which projects from the rotor 1 through the bottom of the cylinder 11.
    Said rotor 1 is engaged integral with the rotation shaft 2 which, in turn, is mounted on bearings 20 of a frame 5;
  • a second rotor 6 or auxiliary rotor, in the form of a cylindrical capsule, surrounding the main rotor 1 and mounted on bearings 61 of the frame 5 so as to rotate around its own axis "z" which is parallel to that "Z" of rotation of the main rotor 1 and whose eccentricity "E" is equal to said distance "e". Said auxiliary rotor 6 is connected to the main rotor 1 by means of four binoculars 7 coplanar and oriented in the same way, which rotate around two corresponding axes "z1 and z6" parallel to each other and to the axis "Z" of the main rotor 1 and the reciprocal distance of which is equal to said eccentricity "E".
    The foot 40 of each connecting rod 4 of the main rotor 1 is articulated to said auxiliary rotor 6 by means of a pin 63 whose axis "z4" is parallel to that "Z" of rotation of the main rotor 1;
  • means 8 for distributing the compressed air to the cylinders 11 of the main rotor 1, comprising a cylindrical body 80 fixed axially on the frame 5 and the body of which is provided with two conduits 81 and 82, one 81 for introduction compressed air in the cylinders 11 through a corresponding lateral opening 12 of the cylinders and the other 82 for the evacuation of the spent air from the cylinders 11 through the same opening 12 after an angular rotation of the main rotor 1 necessary to conclude the active phase.

En référence aux Fig. 4 et 5 des dessins annexés, le pied de bielle 40 de chaque bielle 4 est embo té sur le bouton 71 d'une manivelle intermédiaire correspondante 70 dont un des pivots est en ligne et accouplé avec le bouton 72 d'une jumelle correspondante 7. La longueur des bras 73 de ladite manivelle 70, en relation avec celle desdites jumelles 7, détermine la longueur de la course des pistons 3 de sorte qu'elle peut être présélectionnée de manière appropriée pour obtenir une course des pistons 3 qui soit supérieure ou inférieure à "2E".With reference to Figs. 4 and 5 of the accompanying drawings, the connecting rod foot 40 of each connecting rod 4 is fitted on the button 71 of a corresponding intermediate crank 70, one of the pivots of which is in line and coupled with the button 72 of a corresponding binocular 7. The length of the arms 73 of said crank 70, in relation to that of said binoculars 7, determines the length of the stroke of the pistons 3 so that it can be suitably preselected to obtain a stroke of the pistons 3 which is greater or less to "2E".

Il est possible de modifier le nombre de cylindres 11 pour chaque couronne, et de réaliser un rotor principal 1 avec une ou plusieurs couronnes de cylindres 11: le contour du rotor principal 1 pouvant être correspondant à une quelconque figure plane fermée simple telle que le cercle ou un polygone.It is possible to modify the number of cylinders 11 for each crown, and to produce a main rotor 1 with one or more crowns of cylinders 11: the outline of the main rotor 1 possibly corresponding to any simple closed planar figure such as the circle or a polygon.

De la même manière, le rotor auxiliaire 6 peut être associé aux bielles 4 d'une ou plusieurs couronnes de cylindres 11 et ainsi à un ou plusieurs rotors principaux 1. Il va de soi que plusieurs rotors, principal et auxiliaire 1 et 6, peuvent être montés en ligne, avec un seul arbre moteur 2.
Par ailleurs, les axes "x" des cylindres 11 de chaque couronne appartenant à un même rotor principal 1 peuvent être coplanaires ou autrement placés sur des plans parallèles et peuvent avoir une quelconque direction, parallèle ou co ncidente avec des rayons correspondants du rotor principal respectif.Similarly, the auxiliary rotor 6 can be associated with the connecting rods 4 of one or more cylinder crowns 11 and thus with one or more main rotors 1. It goes without saying that several rotors, main and auxiliary 1 and 6, can be mounted in line, with a single drive shaft 2.
Furthermore, the axes "x" of the cylinders 11 of each ring belonging to the same main rotor 1 can be coplanar or otherwise placed on parallel planes and can have any direction, parallel or coincident with corresponding radii of the respective main rotor .

Il est tout à fait évident qu'en actionnant l'arbre 2 de l'extérieur, le dispositif peut fonctionner en pompe aspirante ou en compresseur.
De la même manière, le moteur selon l'invention peut exploiter l'énergie thermique et de ce fait il peut fonctionner comme un moteur à combustion externe (par exemple à vapeur d'eau) ou à combustion interne (par exemple aux vapeurs d'essence).It is quite obvious that by actuating the shaft 2 from the outside, the device can operate as a suction pump or as a compressor.
In the same way, the engine according to the invention can exploit thermal energy and therefore it can function as an external combustion engine (for example with steam) or internal combustion (for example with steam essence).
