Abstract
Description
La présente invention concerne un dispositif placé dans le réservoir, dispositif destiné à réchauffer le carburant (gas-oil ou fuel) nécessaire à l'alimentation des moteurs diesels. The present invention relates to a device placed in the tank, device intended to heat the fuel (diesel or fuel oil) necessary for the supply of diesel engines.
Lorsque la température descend en-dessous de - 50 C température variable selon le degré de raffinement) les fuels et les gas-oils cristallisent, la paraffine contenue dans ces liquides forme des paillettes qui obstruent les filtres et souvent même le tuyau d'aspiration et sa crépine placés dans le réservoir. De plus, l'eau de condensation du réservoir, en gelant au niveau du tuyau d'aspiration amplifie ce problème. When the temperature drops below - 50 C variable temperature depending on the degree of refinement) fuels and gas oils crystallize, the paraffin contained in these liquids forms flakes which obstruct the filters and often even the suction pipe and its strainer placed in the tank. In addition, the condensed water in the tank, freezing at the suction pipe amplifies this problem.
Divers dispositifs existent pour pallier à cet inconvénient : réchauffage d'une portion du tuyau d'aspiration du gas-oil, (en dehors du réservoir), réchauffage électrique ou à l'eau chaude des filtres, etc. Various devices exist to overcome this drawback: heating a portion of the diesel fuel suction pipe (outside the tank), electric or hot water heating of the filters, etc.
I1 existe un certificat d'utilité no 2131265 pour un système de réchauffage dans lequel une résistance électrique placée dans un gousset (tube bouchd à une extrémité) est placée à la partie inférieure du rdser- voir, le tuyau d'aspiration se trouvant le plus près possible de la résistance électrique. Ce montage n'est pas toujours possible pour des raisons techniques et, de plus, le chauffage à proximité du tube d'aspiration n'est pas toujours suffisant (déperditions importantes de chaleur dans le réservoir). There is a utility certificate no. 2131265 for a heating system in which an electrical resistance placed in a gusset (plugged tube at one end) is placed at the bottom of the tank, the suction pipe being the most as close as possible to the electrical resistance. This assembly is not always possible for technical reasons and, moreover, the heating near the suction tube is not always sufficient (significant heat losses in the tank).
Le dispositif, selon l'invention, est constitué (fig. 1/4) d'un tuyau d'aspiration (6) et (1), coudé (12). Â la partie supérieure du coude préalablement percé, un gousset (2) est introduit par cette ouverture d'une façon concentrique, à l'intérieur de toute la partie verticale (1) du tuyau d'aspiration. Ce gousset est fixé à la partie inférieure du tuyau d'aspiration par une soudure (14). D'autre part, ce gousset soudé à la partie supérieure dépasse du coude d'environ une largeur du tube d'aspiration. Par l'extrémité ouverte du gousset, au-dessus du coude, la résistance électrique (3) y est glissée jusqu'au fond du gousset. Cette résistance électrique chauffante permet de réchauffer le carburant aspiré par la pompe et destiné à l'alimentation du moteur. Elle ne réchauffe que cette quantité de carburant et non l'ensemble du réservoir. The device according to the invention consists (fig. 1/4) of a suction pipe (6) and (1), bent (12). At the upper part of the previously drilled elbow, a gusset (2) is introduced through this opening in a concentric manner, inside the entire vertical part (1) of the suction pipe. This gusset is fixed to the lower part of the suction pipe by a weld (14). On the other hand, this gusset welded to the upper part exceeds the elbow by about a width of the suction tube. Through the open end of the gusset, above the elbow, the electrical resistance (3) is slid there to the bottom of the gusset. This electric heating resistor makes it possible to heat the fuel sucked in by the pump and intended for supplying the engine. It only heats this quantity of fuel and not the entire tank.
Selon une variante (fig. 2/4), le gousset (2) peut être fixé par soudure ou raccord fileté non pas sur le coude de la partie supérieure du tuyau d'aspiration, mais à la partie inférieure du réservoir, ce gousset
et sa résistance interne se trouvant toujours placés d'une façon concentrique à l'intérieur du tuyau d'aspiration. Lorsque le montage est possible, le gousset peut etre soudé sur le bouchon de vidange (muni éventuellement de sa crépine) (fig. 3/4), préalablement percé. Cela suppose bien sûr que le tuyau d'aspiration se trouve en face du bouchon de vidange. Lorsque le tube d'aspiration est de dimension insuffisante pour recevoir le gousset, il peut être coupé et un manchon (1) de même longueur et d'un diamètre supérieur peut y entre soudé (fig. 2/4 et 3/4).According to a variant (fig. 2/4), the gusset (2) can be fixed by welding or threaded connection not on the elbow of the upper part of the suction pipe, but on the lower part of the tank, this gusset
and its internal resistance being always placed concentrically inside the suction pipe. When mounting is possible, the gusset can be welded to the drain plug (possibly fitted with its strainer) (fig. 3/4), previously drilled. This of course assumes that the suction hose is located opposite the drain plug. When the suction tube is insufficient in size to receive the gusset, it can be cut and a sleeve (1) of the same length and with a larger diameter can be welded into it (fig. 2/4 and 3/4).
La résistance électrique a une puissance de 100 à 200 Watts en courant continu 12 ou 24 Volts. Elle est constituée à partir de fil de Nickelchrome de haute qualité, centré dans des tubes métalliques en acier doux, cuivre ou laiton, par de la poudre d'oxyde de magnésie comprimée sous pression. Ces éléments sont totalement clos et incassables dans leur gaine métallique. Cette résistance est munie d'un capuchon terminal isolant possédant 1 ou 2 orifices pour l'alimentation électrique. Un bouton de contact avec voyant lumineux permet de faire fonctionner cette résistance. The electrical resistance has a power of 100 to 200 Watts in direct current 12 or 24 Volts. It is made from high quality Nickelchrome wire, centered in metallic tubes of mild steel, copper or brass, by powder of magnesia oxide compressed under pressure. These elements are completely closed and unbreakable in their metallic sheath. This resistor is provided with an insulating terminal cap having 1 or 2 orifices for the power supply. A contact button with indicator light enables this resistance to operate.
Un relai électrique peut lui être adjoint.An electrical relay can be added to it.
Selon une variante de la résistance elle-même, celle-ci peut Autre thermostatique ou non, ou encore munie d'un fusible thermique de sécurité fondant à une température donnée. According to a variant of the resistor itself, it may Other thermostatic or not, or even provided with a thermal safety fuse melting at a given temperature.
Selon une variante de montage du système (fig. 4/4), le tuyau d'aspiration peut être monté (soudé ou vissé) sur une plaque métallique (13) muni nie du tuyau de retour de carburant (11), ensemble qui se substitue très facilement à la pièce d'origine non munie du dispositif de réchauffage prévu par le constructeur du véhicule. According to a variant mounting of the system (fig. 4/4), the suction pipe can be mounted (welded or screwed) on a metal plate (13) provided with the fuel return pipe (11), an assembly which very easily replaces the original part not fitted with the heating device provided by the vehicle manufacturer.
Selon une variante du montage précédent, à la place de la plaque métallique (13), une plaque en matière isolante (polyester armé) peut être préférée lorsque le réservoir ne doit pas entre mis à la masse, ce qui permet le montage de la résistance à 1 fil, la mise à la masse ne se faisant que par le tuyau d'aspiration. Un raccord caoutchouc isolant est bien sûr nécessaire à la sortie du tuyau d'aspiration (la fixation du tuyau d'aspiration (6) sur la plaque (13) se fait dans ce cas avec des raccords filetés. According to a variant of the previous assembly, in place of the metal plate (13), a plate made of insulating material (reinforced polyester) may be preferred when the tank must not be grounded, which allows the mounting of the resistance with 1 wire, earthing only by the suction pipe. An insulating rubber connection is of course necessary at the outlet of the suction pipe (the suction pipe (6) is fixed to the plate (13) in this case with threaded connections.
