Description

La présente invention a pour objet un ensemble d'aspiration à filtre intégré pour réservoir à carburant.The present invention relates to a suction assembly with an integrated filter for a fuel tank.

Les ensembles d'aspiration qui équipent les réservoirs à carburant des véhicules automobiles se présentent sous la forme d'un corps en matière plastique qui est fixé de façon étanche sur le réservoir et dont la partie inférieure s'appuie sur le fond du réservoir pour y aspirer le carburant et envoyer ce dernier vers l'extérieur.The suction assemblies which equip the fuel tanks of motor vehicles are in the form of a plastic body which is tightly fixed on the tank and the lower part of which rests on the bottom of the tank to suck up the fuel and send it to the outside.

De tels ensembles d'aspiration comportent extérieurement une tubulure de départ de carburant et une tubulure de retour.Such suction assemblies externally comprise a fuel delivery pipe and a return pipe.

Le carburant quitte le réservoir par la tubulure de départ et est acheminé par une succession de conduites jusqu'au moteur qu'il alimente.The fuel leaves the tank through the starting pipe and is conveyed by a succession of lines to the engine which it supplies.

A l'extérieur du réservoir, le carburant aspiré est débarrassé de ses impuretés au moyen d'un filtre généralement assujetti au réservoir et raccordé à la tubulure de départ de l'ensemble d'aspiration par un tuyau flexible.Outside the tank, the aspirated fuel is freed of its impurities by means of a filter generally subject to the tank and connected to the starting pipe of the suction assembly by a flexible hose.

Cependant, cette disposition du filtre à l'extérieur du réservoir présente de nombreux inconvénients, parmi lesquels on peut citer son prix de revient élevé dans la mesure où il est nécessaire de disposer d'un tuyau flexible reliant l'ensemble d'aspiration conventionnel et le filtre, et d'assujettir ledit filtre au réservoir par un moyen quelconque de préférence amovible, qui permet son remplacement.However, this arrangement of the filter outside the tank has many drawbacks, among which we can cite its high cost price insofar as it is necessary to have a flexible hose connecting the conventional suction assembly and the filter, and to subject said filter to the tank by any means, preferably removable, which allows its replacement.

En outre, le montage séparé de l'ensemble d'aspiration et du filtre implique de longues opérations de manutention.In addition, the separate mounting of the suction assembly and the filter involves long handling operations.

De plus, le remplacement du filtre nécessite le débranchement du tuyau flexible et de la conduite, puis leur remontage sur un nouveau filtre qui a été par ailleurs assujetti au réservoir.In addition, replacing the filter requires disconnecting the flexible hose and the pipe, then reassembling them on a new filter which has also been secured to the tank.

La présente invention vise à fournir un nouvel ensemble d'aspiration dont le prix de revient, ainsi que le coût de montage et de remplacement sont notablement réduits par rapport à ceux constatés dans la technique connue.The present invention aims to provide a new suction assembly whose cost, as well as the cost of assembly and replacement are significantly reduced compared to those found in the known technique.

La présente invention a pour objet un ensemble d'aspiration du type monobloc pour réservoir à carburant, notamment de véhicule automobile, comportant un corps destiné à être monté à l'intérieur dudit réservoir au travers d'un orifice de la paroi supérieure de celui-ci, en étant assujetti par sa partie supérieure à ladite paroi supérieure du réservoir, et un logement pour recevoir un filtre à carburant apte à éliminer les impuretés du carburant avant sa sortie de l'ensemble d'aspiration, caractérisé par le fait que ledit logement pour recevoir ledit filtre à carburant est disposé à ladite partie supérieure dudit corps.The subject of the present invention is a suction unit of the monobloc type for a fuel tank, in particular for a vehicle. automobile, comprising a body intended to be mounted inside said tank through an orifice in the upper wall thereof, being secured by its upper part to said upper wall of the tank, and a housing for receiving a fuel filter capable of removing impurities from the fuel before it leaves the suction assembly, characterized in that said housing for receiving said fuel filter is disposed at said upper part of said body.

Avantageusement, le logement pour recevoir le filtre à carburant débouche à la partie supérieure du corps de l'ensemble d'aspiration, à l'extérieur du réservoir à carburant.Advantageously, the housing for receiving the fuel filter opens out at the upper part of the body of the suction assembly, outside the fuel tank.

Il apparaît clairement que l'ensemble d'aspiration selon l'invention permet de réaliser de substantielles économies de fabrication, de montage et de remplacement dans la mesure où il n'est plus nécessaire de relier le filtre à l'ensemble d'aspiration puisque ce dernier se trouve directement intégré dans le bloc constitué par ledit ensemble d'aspiration.It is clear that the suction assembly according to the invention makes it possible to make substantial savings in manufacturing, assembly and replacement since it is no longer necessary to connect the filter to the suction assembly since the latter is directly integrated into the block formed by said suction assembly.

Dans un mode de réalisation préféré de l'invention, le filtre est engagé de façon amovible dans son logement.In a preferred embodiment of the invention, the filter is removably engaged in its housing.

Ainsi, le filtre peut être remplacé périodiquement à moindre frais, puisque, de par son engagement amovible, il peut être interchangé facilement pour un nombre très limité de manutentions.Thus, the filter can be replaced periodically at low cost, since, by its removable engagement, it can be easily interchanged for a very limited number of handling.

Il n'est en effet nécessaire de démonter ni le réservoir, dans la mesure où le filtre se situe à la partie supérieure du corps de l'ensemble d'aspiration, lequel traverse la paroi supérieure du réservoir, ni le corps de l'ensemble d'aspiration, dans la mesure où le filtre est engagé de façon amovible dans son logement.It is in fact not necessary to disassemble either the reservoir, since the filter is located at the upper part of the body of the suction assembly, which passes through the upper wall of the reservoir, nor the body of the assembly suction, insofar as the filter is removably engaged in its housing.

Dans une variante préférée, le filtre est enfermé dans une cartouche filtrante que l'on maintient dans le logement prévu dans l'ensemble d'aspiration par exemple par clipsage.In a preferred variant, the filter is enclosed in a filter cartridge which is maintained in the housing provided in the suction assembly, for example by clipping.

Selon une autre variante, l'ensemble d'aspiration comporte un couvercle manoeuvrable de l'extérieur qui permet de dégager le logement pour remplacer le filtre si nécessaire.According to another variant, the suction assembly comprises a cover which can be operated from the outside which makes it possible to free the housing to replace the filter if necessary.

Dans ces deux variantes, on comprend que le filtre peut être changé facilement tout au long de la durée de vie du véhicule.In these two variants, it is understood that the filter can be changed easily throughout the life of the vehicle.

Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant deux modes de réalisation donnés à titre d'exemples et sans aucun caractère limitatif de la portée de l'invention en référence au dessin annexé dans lequel :

  • la figure 1 représente un ensemble d'aspiration selon un premier mode de réalisation de l'invention, et
  • la figure 2 représente un ensemble d'aspiration selon un second mode de réalisation de l'invention.
In order to better understand the invention, we will now describe two embodiments given as of examples and without any limiting character of the scope of the invention with reference to the attached drawing in which:
  • FIG. 1 represents a suction assembly according to a first embodiment of the invention, and
  • FIG. 2 represents a suction assembly according to a second embodiment of the invention.

Sur la figure 1, on a représenté un mode de réalisation d'un ensemble d'aspiration selon l'invention constitué par un corps en matière plastique 1 qui comporte à sa partie supérieure une collerette 2 permettant d'assujettir l'ensemble d'aspiration à la paroi supérieure d'un réservoir de carburant 3. L'ensemble d'aspiration est engagé dans un orifice 4, sa collerette 2 étant maintenue serrée sur l'orifice 4 par vissage d'un bouchon 5.In Figure 1, there is shown an embodiment of a suction assembly according to the invention consisting of a plastic body 1 which has at its upper part a flange 2 for securing the suction assembly to the upper wall of a fuel tank 3. The suction assembly is engaged in an orifice 4, its flange 2 being held tight on the orifice 4 by screwing a plug 5.

L'ensemble d'aspiration décrit ici laisse dépasser du réservoir 3 une tubulure de départ de carburant 6 ainsi qu'une tubulure de retour de carburant 7.The suction assembly described here leaves a fuel outlet pipe 6 and a fuel return pipe 7 protruding from the tank 3.

Dans le cas présent, la tubulure 6 est constituée par la tubulure de sortie d'une cartouche filtrante 8 qui est logée, selon l'invention, à l'intérieur de la partie supérieure du corps 1.In the present case, the tubing 6 is constituted by the outlet tubing of a filter cartridge 8 which is housed, according to the invention, inside the upper part of the body 1.

Conformément à l'invention, le logement 9 recevant la cartouche filtrante débouche à la partie supérieure du corps 1 de l'ensemble d'aspiration, à l'extérieur du réservoir 3, de sorte que l'accès à la cartouche filtrante 8 est particulièrement aisé.According to the invention, the housing 9 receiving the filter cartridge opens at the upper part of the body 1 of the suction assembly, outside the tank 3, so that access to the filter cartridge 8 is particularly easy.

La cartouche filtrante 8 est maintenue par clipsage dans le logement 9 du corps 1, avec sa périphérie 10 en appui sur une rainure annulaire 11 du corps 1.The filter cartridge 8 is held by clipping into the housing 9 of the body 1, with its periphery 10 bearing on an annular groove 11 of the body 1.

Ce contact périphérique permet, dans le cas présent, de réaliser entre l'extérieur et le logement 9 une étanchéité qui est nécessaire, du fait que l'on a prévu un orifice de vidange 9a dans ce logement, pour le vider de son contenu lors du remplacement de la cartouche filtrante 8.This peripheral contact makes it possible, in the present case, to produce between the exterior and the housing 9 a seal which is necessary, owing to the fact that a drain orifice 9 a has been provided in this housing, to empty it of its content when replacing the filter cartridge 8.

En effet, cette dernière est susceptible de contenir encore du carburant au moment où elle est retirée du logement 9, et de déverser ce carburant dans le logement 9, lequel se vide à son tour par l'orifice 9a.Indeed, the latter is likely to still contain fuel when it is removed from the housing 9, and to pour this fuel into the housing 9, which in turn empties through the orifice 9 a .

Cependant, dans le cas où la cartouche filtrante 8 ne laisse échapper que très peu de carburant lors de son retrait, on peut se passer de l'orifice 9a et, par suite, de l'étanchéité périphérique. entre la cartouche filtrante 8 et la rainure annulaire 11.However, in the case where the filter cartridge 8 lets out very little fuel during its removal, it is possible to pass from the orifice 9 a and, consequently, from the peripheral seal. between the filter cartridge 8 and the annular groove 11.

La cartouche filtrante 8 renferme un filtre 12.The filter cartridge 8 contains a filter 12.

Un orifice 13, situé à la partie inférieure de la cartouche filtrante, coïncide avec un orifice 14 ménagé dans le logement 9.An orifice 13, located at the lower part of the filter cartridge, coincides with an orifice 14 formed in the housing 9.

Ces orifices 13 et 14 permettent à une pompe 15 d'être maintenue à l'intérieur du corps 1 en-dessous du logement 9, avec sa tubulure de sortie de carburant 16 engagée dans les orifices précités.These orifices 13 and 14 allow a pump 15 to be held inside the body 1 below the housing 9, with its fuel outlet pipe 16 engaged in the above-mentioned orifices.

La tubulure 16 se termine par un bourrelet 17 qui limite son coulissement vers le bas.The tubing 16 ends in a bead 17 which limits its sliding downwards.

Un joint 18 permet à la fois d'assurer l'étanchéité entre la tubulure 16 et la cartouche filtrante 8 et de maintenir la pompe 15 suspendue par sa tubulure 16 à l'intérieur des orifices 13 et 14.A seal 18 makes it possible both to ensure the seal between the tube 16 and the filter cartridge 8 and to keep the pump 15 suspended by its tube 16 inside the orifices 13 and 14.

L'ensemble d'aspiration décrit ici comporte à sa partie inférieure un bac 19 qui prend appui sur le fond 20 du réservoir 3 et dans lequel une crépine 21 est logée en étant directement raccordée à la tubulure 22 d'entrée du carburant dans la pompe 15.The suction assembly described here has at its lower part a tank 19 which bears on the bottom 20 of the tank 3 and in which a strainer 21 is housed by being directly connected to the pipe 22 for entering the fuel into the pump. 15.

Le bac 19 est monté axialement coulissant sur le corps 1, de sorte que la hauteur de l'ensemble d'aspiration s'adapte aux variations de hauteur du réservoir 3 soumis à des dilatations thermiques notamment.The tank 19 is mounted axially sliding on the body 1, so that the height of the suction assembly adapts to variations in height of the tank 3, in particular subjected to thermal expansion.

Pour le retour du carburant, l'ensemble d'aspiration selon ce mode de réalisation comporte un tuyau de retour 23 dont on n'a représenté ici que la partie supérieure.For the return of the fuel, the suction assembly according to this embodiment comprises a return pipe 23 of which only the upper part has been shown here.

La figure 2 représente un ensemble d'aspiration analogue à celui représenté sur la figure 1 à la différence près qu'il comporte un filtre 12 qui n'est pas pourvu de moyens de fixation dans le logement 9 du corps 1, ce dernier étant par contre muni d'un couvercle 24 dont la périphérie 10' vient se clipser d'une façon étanche sur la rainure annulaire 11 du corps 1.2 shows a suction assembly similar to that shown in Figure 1 except that it includes a filter 12 which is not provided with fixing means in the housing 9 of the body 1, the latter being by against provided with a cover 24 whose periphery 10 'is clipped in a sealed manner on the annular groove 11 of the body 1.

Il est indispensable ici que le logement 9 soit parfaitement étanche, puisqu'il tient lieu d'enveloppe pour le filtre 12.It is essential here that the housing 9 is perfectly sealed, since it acts as an envelope for the filter 12.

Dans ce cas, on ouvre le couvercle 24 pour remplacer le filtre 12.In this case, the cover 24 is opened to replace the filter 12.

Il apparaît clairement sur les modes de réalisation décrits que l'ensemble d'aspiration selon l'invention permet de faire l'économie d'un tuyau flexible reliant sa tubulure de départ de carburant à un filtre situé à l'extérieur du réservoir et qu'en outre, un ensemble d'aspiration selon l'invention présente extérieurement des dimensions sensiblement identiques à celles d'un ensemble d'aspiration traditionnel, et peut par conséquent remplacer ce dernier dans des utilisations existantes.It is clear from the embodiments described that the suction assembly according to the invention makes it possible to save on a flexible hose connecting its fuel starting pipe to a filter located outside the tank and that in addition, a suction assembly according to the invention has externally dimensions substantially identical to those of a traditional suction assembly, and can therefore replace the latter in uses existing.

Par ailleurs, l'ensemble d'aspiration selon l'invention présente l'avantage important que le filtre peut être facilement interchangé sans que le démontage d'aucune pièce ne soit requis. On peut ainsi aisément remplacer le filtre à carburant d'un véhicule tout au long de la durée de vie de ce dernier.Furthermore, the suction assembly according to the invention has the important advantage that the filter can be easily interchanged without the disassembly of any part being required. It is thus easy to replace the fuel filter of a vehicle throughout the lifetime of the latter.

Il est bien entendu que les modes de réalisation qui viennent d'être décrits ne présentent aucun caractère limitatif et qu'ils pourront recevoir toutes modifications désirables sans sortir pour cela du cadre de l'invention.It is understood that the embodiments which have just been described have no limiting character and that they can receive any desirable modifications without departing from the scope of the invention.
