Abstract
Description
La présente invention concerne un réehauffeur défigeur de gazole pour véhicule à moteur diesel. The present invention relates to a diesel fuel reheater heater for a diesel engine vehicle.
Par temps froid (au-dessous de -5 environ), le gazole forme des cristaux de paraffine qui obturent les filtres ou prefiltres des moteurs diesel
On a déjà réalisé des dispositifs réchauSfeurs- dfigeurs qui ont pour inconvénient d'entrainer un coût élevé par les éléments qui les composent et qui peuvent eux-mêmes avoir des pannes de fonctionnement.In cold weather (below about -5), diesel fuel forms paraffin crystals which clog filters or prefilters of diesel engines.
We have already produced reheating devices which have the disadvantage of causing a high cost by the elements which compose them and which themselves may have operating failures.
La présente invention a pour objet un réchauffeur- défigeur qui a pour avantages o une absence de circuits électriques et d'éléments mecaniques, un fonctionnement entièrement automatique et un prix de revient modique
L'appareil est constitué par un segment de tube autour duquel on a monté en spirale et soudé un second segment de tube de plus petite section, le premier segment de tube étant intercalé et monté sur le circuit de chauf- fage du véhicule, tandis que le second segment de tube est intercalé et monté sur la canalisation d'arrivée au filtre eu an préfiltre du gazole à réchaufferO
Selon un mode préféré de réalisation de l'invention, le premier segment de tube est intercalé dans le circuit de chauffage sur la section qui vient de la pompe à eau et qui va au radiateur de chauffage
Selon un autre mode préféré de réalisation, les segments de tube sont en cuivre et les soudures à l'étain afin de favoriser le transport de chaleur de l'eau au gazole.The subject of the present invention is a heater-deflector which has the advantages o an absence of electrical circuits and mechanical elements, fully automatic operation and a low cost price.
The apparatus consists of a tube segment around which a second segment of tube of smaller section has been spirally mounted and welded, the first tube segment being inserted and mounted on the heating circuit of the vehicle, while the second segment of the tube is inserted and mounted on the inlet pipe to the filter having a prefilter of diesel fuel to be heated
According to a preferred embodiment of the invention, the first segment of tube is inserted in the heating circuit on the section which comes from the water pump and which goes to the heating radiator
According to another preferred embodiment, the tube segments are made of copper and the tin solders in order to promote the transport of heat from water to diesel.
La description qui suit, faite en regard des dessins annexés donnés à titre d'exemple non limitatif permettra de mieux comprendre l'invention. The description which follows, given with reference to the appended drawings given by way of nonlimiting example, will allow a better understanding of the invention.
Dans ces dessins
- La figure 1 représente l'appareil vu en perspective,
- La figure 2, une coupe longitudinale de la figure 1. In these drawings
FIG. 1 represents the device seen in perspective,
- Figure 2, a longitudinal section of Figure 1.
Sur le segment de tube i est soudé en spirale 3 un segment de tube de plus petite section 2. L'eau du circuit de chauffage se déplace dans le tube 1 selon la direction des flèches F1-F2, tandis que le gazole se déplace dans le tube 2 selon les flèches F3-F4. On the tube segment i is spirally welded 3 a tube segment of smaller section 2. The water of the heating circuit moves in the tube 1 in the direction of the arrows F1-F2, while the diesel moves in tube 2 according to arrows F3-F4.
Les extrémités des segments de tubes 1 et 2 sont reliées aux circuits respectifs de fluides par des durites. The ends of the tube segments 1 and 2 are connected to the respective fluid circuits by hoses.
Le conducteur du véhicule, suivant la température extérieure, ouvre, ferme ou régule le chauffage intérieur et, par la même manoeuvre, il ouvre, ferme ou régule le réchauffeur-défigeur. The driver of the vehicle, depending on the outside temperature, opens, closes or regulates the interior heating and, by the same operation, he opens, closes or regulates the heater-heater.
Le fonctionnement étant ainsi entièrement automatique, le conducteur peut ignorer la présence de cet appareil; aucun risque de panne de celui-ci n'est à redouter puisqu'il ne comporte aucun élément mécanique ou électrique. The operation is thus fully automatic, the driver can ignore the presence of this device; no risk of failure of the latter is to be feared since it does not comprise any mechanical or electrical element.
La conception de l'appareil écarte tout risque de mélange eau-gazole (les circuits entant entièrement indépendants) et tout risque d'enflammer le gazole (comme il en existe avec un système de réchauffage électrique). The design of the device eliminates any risk of water-diesel mixture (the circuits being entirely independent) and any risk of igniting the diesel (as there is with an electric heating system).
Le moteur diesel sur lequel a été monté l'nappa reil conforme à l'invention n'est plus exposé à des pannes d'alimentation sur route, par bouchage du ou des filtres ou préfiltres d'arrivée de gazole dans la pompe à injection. The diesel engine on which the apparatus according to the invention has been mounted is no longer exposed to road supply failures, by clogging of the filter or filters or pre-filters for the arrival of diesel fuel in the injection pump.
Le fonctionnement du moteur est amélioré et on réalise une économie de carburant par une meilleure combustion du gazole réchauffe. Engine operation is improved and fuel economy is achieved by better combustion of the heated diesel.
Par températeur douce, le chauffage intérieur du véhicule étant coupé, l'appareil est isolé. By soft temperature control, the interior heating of the vehicle being cut, the device is isolated.
Il est bien evident que l'on peut apporter à cette réalisation des modifications de détails, sans pour cela, s'écarter du cadre de l'invention. It is quite obvious that one can make modifications of details to this embodiment, without thereby departing from the scope of the invention.
