Abstract
Description
Afin de pouvoir continuer à pomper du carburant dans le réservoir d'un véhicule lorsque le volume de ce carburant dans le réservoir s'épuise, on utilise souvent un piège, c'est-à-dire un bac de retenue fixé sur le fond du réservoir et limité par des parois de faible hauteur, 1' T aspiration se faisant à l'intérieur du piège.In order to be able to continue pumping fuel into the tank of a vehicle when the volume of this fuel in the tank runs out, a trap is often used, that is to say a retaining tank fixed on the bottom of the tank and limited by walls of low height, the suction being done inside the trap.
Cependant, en cas de virage ou de mouvements plus ou moins brusques, le piège risque de se vider d'un coup, entraînant un désamorçage de la pompe.However, in the event of a turn or more or less abrupt movements, the trap may be emptied suddenly, leading to a defusing of the pump.
De plus, si la jauge se trouve à proximité immédiate de l'aspiration, comme c'est souvent le cas, elle donnera une indication correspondant à la hauteur de carburant dans le piège, qui peut être plus élevée que dans le reste du réservoir, ce qui est trompeur.In addition, if the gauge is in the immediate vicinity of the suction, as is often the case, it will give an indication corresponding to the height of fuel in the trap, which may be higher than in the rest of the tank, which is misleading.
Le piège selon l'invention est caractérisé en ce que ses deux parois longitudinales sont percées d'orifices associés à des moyens anti-retour et permettant l'introduction du carburant dans le piège en empêchant sa sortie et en ce qu'il comporte à sa base au moins un orifice supplémentaire ouvert en permanence.The trap according to the invention is characterized in that its two longitudinal walls are pierced with orifices associated with non-return means and allowing the introduction of the fuel into the trap by preventing its exit and in that it comprises at its base at least one additional opening permanently open.
Dans un virage, les moyens anti-retour empêchent le piège de se vider brusquement tout en permettant au carburant de passer dans le piège; il n'y a donc aucun risque de désamorçage de la pompe.In a bend, the non-return means prevent the trap from emptying suddenly while allowing the fuel to pass into the trap; there is therefore no risk of defusing the pump.
L'orifice supplémentaire permet néanmoins une égalisation des niveaux dans le piège et dans le réservoir de sorte que la jauge donne une indication exacte.The additional opening nevertheless allows equalization of the levels in the trap and in the tank so that the gauge gives an exact indication.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du piège selon l'invention, avec référence aux dessins annexés dans lesquels
La Figure 1 est une vue en perspective
du piège;
La Figure 2 en est une coupe transversale,
en position de repos;
La Figure 3 est une vue semblable à la
Figure 2, dans un virage à gauche.An embodiment of the trap according to the invention has been described below, by way of non-limiting example, with reference to the appended drawings in which
Figure 1 is a perspective view
of the trap;
Figure 2 is a cross section,
in the rest position;
Figure 3 is a view similar to the
Figure 2, in a left turn.
Tel qu'il est représenté aux dessins, le piège à carburant selon l'invention est constitué par un bac de retenue 1, de section carrée ou rectangulaire, fixé dans le fond d'un réservoir de carburant 2. Les deux parois longitudinales la de cé bac sont obliques en étant inclinées vers le bas et vers l'intérieur alors que ses deux parois transversales ld sont sensiblement verticales; la hauteur de ces parois est inférieure à celle des parois du réservoir 2. Le conduit d'aspiration 3 débouche à l'intérieur du bac; une jauge non représentée est disposée à proximité de ce conduit.As shown in the drawings, the fuel trap according to the invention consists of a retaining tank 1, of square or rectangular section, fixed in the bottom of a fuel tank 2. The two longitudinal walls 1a of these tanks are oblique while being inclined downwards and inwards while its two transverse walls ld are substantially vertical; the height of these walls is less than that of the walls of the tank 2. The suction duct 3 opens out inside the tank; a gauge, not shown, is disposed near this conduit.
Un volet 4 est disposé sur la face interne de chacune des parois longitudinales la et monté pivotant autour d'un axe 5 sensiblement horizontal.A flap 4 is arranged on the internal face of each of the longitudinal walls la and mounted to pivot about a substantially horizontal axis 5.
Sous l'effet de son poids le volet vient normalement s'appliquer sur la face interne de la paroi, la partie de cette face ainsi recouverte étant percée d'orifices 6. Un orifice supplémentaire 7 est percé dans la partie inférieure de chacune des parois latérales la en dessous de la partie recouverte par le volet 4.Under the effect of its weight, the flap is normally applied to the internal face of the wall, the part of this face thus covered being pierced with holes 6. An additional hole 7 is pierced in the lower part of each of the walls. the side below the part covered by the flap 4.
En ligne droite ou à l'arrêt (Figure 2), le bac 1 contient du carburant qui s'y trouve au même niveau que dans le réservoir 2 étant donné la présence des trous 7; l'indication donnée par la jauge est donc exacte.In a straight line or at a standstill (Figure 2), the tank 1 contains fuel which is there at the same level as in the tank 2 given the presence of the holes 7; the indication given by the gauge is therefore correct.
Dans un virage, le carburant situé du côté intérieur du virage tend à passer au côté opposé, sous l'effet de la force centrifuge; il repousse le volet 4 correspondant et s'introduit dans le bac (Figure 3). Le volet 4 opposé est appliqué sur sa paroi sous l'effet tant de la force centrifuge que du poids du carburant se trouvant dans le bac ; il retient donc ce carburant et empêche un vidage brutal du bac. Les niveaux dans le bac et dans la partie du réservoir située du côté extérieur au virage finissent cependant par s'égaliser, le bac se vidant par le trou 7 de la paroi la située du côté extérieur.In a bend, the fuel located on the inside of the bend tends to pass to the opposite side, under the effect of centrifugal force; it pushes the corresponding flap 4 back and enters the tank (Figure 3). The opposite flap 4 is applied to its wall under the effect of both the centrifugal force and the weight of the fuel in the tank; it therefore retains this fuel and prevents a sudden emptying of the tank. The levels in the tank and in the part of the tank located on the outside of the bend, however, end up leveling off, the tank emptying through hole 7 in the wall 1a located on the outside.
I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. C'est ainsi, en particulier, que les parois transversales lb pourraient être inclinées et comporter également des volets. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof. Thus, in particular, the transverse walls 1b could be inclined and also include flaps.
