Abstract
Description
La présente invention a essentiellement pour objet un dispositif de transfert de carburant depuis une poche annexe à la poche principale d'un réservoir de carburant appartenant à un véhicule automobile par exemple. The present invention essentially relates to a fuel transfer device from a pocket annexed to the main pocket of a fuel tank belonging to a motor vehicle for example.
L'architecture d'un soubassement de véhicule conduit parfois à réaliser des réservoirs de carburant à deux poches de façon à contourner un organe mécanique et de façon à conserver le volume de remplissage requis pour le réservoir. The architecture of a vehicle base sometimes leads to the production of two-pocket fuel tanks so as to bypass a mechanical member and so as to maintain the filling volume required for the tank.
Un tel réservoir nécessite donc des moyens de transfert du carburant d'une poche à l'autre pour pouvoir vider complètement la poche annexe. Such a tank therefore requires means for transferring fuel from one pocket to the other in order to be able to completely empty the annex pocket.
A cet effet, il a déjà été proposé d'utiliser une pompe à carburant auxiliaire avec un système de mise en route et d'arrêt en fonction du niveau de carburant. To this end, it has already been proposed to use an auxiliary fuel pump with a starting and stopping system depending on the fuel level.
I1 a aussi été proposé d'utiliser un venturi sur la conduite de retour du carburant en provenance du moteur, et de le raccorder par une canalisation à la poche annexe du réservoir pour ainsi permettre l'aspiration du carburant dans cette poche annexe et son alimentation à la poche principale. It has also been proposed to use a venturi on the return line of the fuel coming from the engine, and to connect it by a pipe to the annex pocket of the tank so as to allow the suction of the fuel in this annex pocket and its supply. to the main pocket.
Dans cette disposition, la canalisation précitée passe au-dessus du réservoir et donne satisfaction avec de l'essence, mais elle ne fonctionne pas avec du gazole, car le débit des pompes à injection et la limitation de la contrepression en aval de la pompe ne permettent pas la création d'une dépression suffisante pour aspirer le carburant jusqu'au-dessus du réservoir. In this arrangement, the above-mentioned pipe passes over the tank and gives satisfaction with petrol, but it does not work with diesel, because the flow rate of the injection pumps and the limitation of the back pressure downstream of the pump does not not allow the creation of a sufficient vacuum to suck the fuel up above the tank.
La présente invention a donc pour but de remédier notamment à cet inconvénient en proposant un dispositif de transfert de carburant qui fonctionne avec une hauteur d'aspiration très réduite et correspondant à la seule dénivellation séparant les deux poches. The aim of the present invention is therefore to remedy this drawback in particular by proposing a fuel transfer device which operates with a very reduced suction height and corresponding to the only difference in level separating the two pockets.
A cet effet, l'invention a pour objet un dispositif de transfert de carburant depuis une poche annexe à la poche principale d'un réservoir de carburant pour véhicule automobile, et du type comprenant un venturi prévu sur la conduite de retour du carburant à la poche principale et raccordé par une canalisation à la poche annexe du réservoir, caractérisé en ce que le venturi est solidaire d'un bouchon ou analogue d'obturation de la poche principale et en ce que ladite canalisation traverse une paroi de la poche principale pour d'un côté se raccorder au venturi introduit dans cette poche par mise en place du bouchon et de l'autre côté assurer par l'extérieur du réservoir, en passant immédiatement au-dessus d'un seuil définissant une séparation entre les deux poches, la communication avec la poche annexe du réservoir. To this end, the subject of the invention is a device for transferring fuel from a pocket annexed to the main pocket of a fuel tank for a motor vehicle, and of the type comprising a venturi provided on the line for returning the fuel to the main pocket and connected by a pipe to the annex pocket of the tank, characterized in that the venturi is integral with a plug or the like closing the main pocket and in that said pipe passes through a wall of the main pocket to '' connect one side to the venturi introduced into this pocket by fitting the plug and on the other side ensure from the outside of the tank, passing immediately above a threshold defining a separation between the two pockets, the communication with the annex pocket of the tank.
On comprend donc que la canalisation de transvasement passe ainsi à l'extérieur du réservoir au niveau de la séparation des deux poches, le venturi étant situé à l'intérieur de la poche principale dudit réservoir. It is therefore understood that the transfer pipe thus passes outside the tank at the separation of the two pockets, the venturi being located inside the main pocket of said tank.
Selon une autre caractéristique de l'invention, le venturi est dans le prolongement de la conduite de retour du carburant qui plonge dans la poche principale et qui est solidaire d'un couvercle monté tournant à l'intérieur d'un écrou qui le plaque contre un joint d'étanchéité. According to another characteristic of the invention, the venturi is in the extension of the fuel return line which plunges into the main pocket and which is secured to a cover mounted to rotate inside a nut which presses it against a seal.
Suivant une autre caractéristique du dispositif de l'invention, le venturi possède une ouverture circulaire latérale orientée à 450C vers le bas par rapport à l'axe de la conduite de retour et munie d'un joint à lèvres assurant une liaison étanche entre ladite ouverture et l'extrémité débouchante de la canalisation traversant la paroi précitée de la poche principale. According to another characteristic of the device of the invention, the venturi has a lateral circular opening oriented at 450C downward relative to the axis of the return pipe and provided with a lip seal ensuring a tight connection between said opening and the through end of the pipe passing through the aforementioned wall of the main pocket.
On précisera encore ici que l'extrémité débouchante de la canalisation comporte une collerette située dans un plan formant un angle de 45"C par rapport à l'axe de ladite extrémité et permettant ainsi la liaison étanche entre le venturi et la canalisation lors du vissage de l'écrou précité. It will also be specified here that the through end of the pipe comprises a flange situated in a plane forming an angle of 45 "C with respect to the axis of said end and thus allowing the tight connection between the venturi and the pipe during screwing of the aforementioned nut.
Suivant encore une autre caractéristique du dispositif selon cette invention, il est prévu des moyens d'indexage assurant la coïncidence entre l'ouverture latérale du venturi et l'extrémité débouchante de la canalisation lors du vissage du bouchon sur la poche principale. According to yet another characteristic of the device according to this invention, indexing means are provided ensuring the coincidence between the lateral opening of the venturi and the through end of the pipe when the plug is screwed onto the main pocket.
Suivant un exemple de réalisation préféré, les moyens d'indexage précités sont constitués par une jupe circulaire solidaire du couvercle et munie d'une encoche apte à recevoir un doigt ou analogue solidaire de la paroi latérale de la poche principale du réservoir. According to a preferred embodiment, the aforementioned indexing means consist of a circular skirt secured to the cover and provided with a notch capable of receiving a finger or the like secured to the side wall of the main pocket of the reservoir.
Mais d'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels:
- la figure 1 est une vue en élévation et partiellement en coupe d'un réservoir de carburant équipé du dispositif selon cette invention;
- la figure 2 est une vue en plan et de dessus du réservoir suivant la flèche II de la figure 1
- la figure 3 est une vue extérieure schématique et en perspective du réservoir
- la figure 4 est une vue en coupe suivant la ligne IV-IV de la figure 1; et
- la figure 5 est une vue des moyens d'indexage suivant la flèche V de la figure 4. However, other characteristics and advantages of the invention will appear better in the detailed description which follows and refers to the appended drawings, given solely by way of example, and in which:
- Figure 1 is an elevational view partially in section of a fuel tank equipped with the device according to this invention;
- Figure 2 is a plan view and from above of the tank according to arrow II of Figure 1
- Figure 3 is a schematic perspective view of the tank
- Figure 4 is a sectional view along the line IV-IV of Figure 1; and
FIG. 5 is a view of the indexing means according to arrow V in FIG. 4.
En se reportant plus particulièrement aux figures 1 à 3, on voit un réservoir 1 de carburant pour véhicule automobile comprenant une poche principale 2 et une poche annexe 3 communiquant avec la poche principale 2 et séparée de cette dernière par un seuil 4 contournant un organe mécanique quelconque (non représenté) trouvant place sous ledit seuil. Referring more particularly to Figures 1 to 3, we see a fuel tank 1 for motor vehicle comprising a main pocket 2 and an annex pocket 3 communicating with the main pocket 2 and separated from the latter by a threshold 4 bypassing a mechanical member any (not shown) finding place under said threshold.
On a montré en 5 un tube de puisage du carburant dans la poche principale 2, et en 6 un tube de retour du carburant, en provenance du moteur, au réservoir. Les tubes 5 et 6 débouchent, comme on le voit bien sur les figures 1 et 4 dans une petite cuve 7 solidaire du fond de la poche principale 2 du réservoir 1 et dans laquelle s'effectuent le puisage et le rejet du carburant. 5 shows a fuel drawing tube in the main pocket 2, and 6 shows a fuel return tube, coming from the engine, to the tank. The tubes 5 and 6 open out, as can be seen in FIGS. 1 and 4 in a small tank 7 secured to the bottom of the main pocket 2 of the tank 1 and in which the fuel is drawn and discharged.
Sur la conduite 6 de retour du carburant, est prévu un venturi 8 qui est raccordé par une canalisation 9 à la poche annexe 3. On the fuel return line 6, a venturi 8 is provided which is connected by a line 9 to the annex pocket 3.
Conformément à l'invention, la conduite 6 avec son venturi associé 8 qui est dans le prolongement de cette conduite, est solidaire d'un bouchon 10 d'obturation de la poche principale 2 du réservoir 1. Ce bouchon 10, comme on le voit bien sur les figures 1 et 4, se compose d'un couvercle 11 dont est solidaire la conduite 6, et d'un écrou 12 permettant le serrage du couvercle 11 sur le réservoir 1. According to the invention, the pipe 6 with its associated venturi 8 which is an extension of this pipe, is secured to a plug 10 for closing the main pocket 2 of the tank 1. This plug 10, as can be seen indeed in FIGS. 1 and 4, consists of a cover 11 to which the pipe 6 is attached, and of a nut 12 allowing the cover 11 to be tightened on the tank 1.
On a montré en 13 sur la figure 4 un joint d'étanchéité entre le couvercle 11 et un bord la du réservoir 1 définissant, pour le réservoir, une ouverture 14 obturable par le bouchon 10. On observera ici que le couvercle 11 est monté tournant dans l'écrou 12. There is shown at 13 in FIG. 4 a seal between the cover 11 and an edge 1a of the tank 1 defining, for the tank, an opening 14 closable by the plug 10. It will be observed here that the cover 11 is mounted to rotate in nut 12.
La canalisation 9 raccordée au venturi 8 de la façon qui sera décrite en détail plus loin, traverse une paroi 2a de la poche principale 2 du réservoir 1 pour, d'un côté, se raccorder au venturi 8 introduit dans ladite poche par mise en place du bouchon 10 et pour, de l'autre côté, assurer par l'extérieur du réservoir 1, en passant immédiatement au-dessus du seuil 4 définissant la séparation entre les deux poches 2 et 3, la communication avec la poche annexe 3. The pipe 9 connected to the venturi 8 in the manner which will be described in detail below, passes through a wall 2a of the main pocket 2 of the reservoir 1 in order, on the one hand, to connect to the venturi 8 introduced into said pocket by positioning of the plug 10 and for, on the other side, ensuring from the outside of the tank 1, passing immediately above the threshold 4 defining the separation between the two pockets 2 and 3, the communication with the annex pocket 3.
On a montré en 9a sur les figures 1 et 3 une pipette raccordée à la canalisation 9 et plongeant dans la poche annexe 3 du réservoir, et on a montré en 9b sur les figures 3 et 4 une autre pipette fixée, par exemple soudée, sur la paroi verticale 2a du réservoir à hauteur du venturi 8, ce qui permet à la canalisation 9 d'être horizontale au niveau du seuil 4 depuis la sortie de la pipette 9a jusqu'à, et y compris, la pipette 9b. We have shown in 9a in Figures 1 and 3 a pipette connected to the pipe 9 and plunging into the annex pocket 3 of the tank, and we have shown in 9b in Figures 3 and 4 another pipette attached, for example welded, on the vertical wall 2a of the reservoir at the height of the venturi 8, which allows the pipe 9 to be horizontal at the threshold 4 from the outlet of the pipette 9a to, and including, the pipette 9b.
Autrement dit, la canalisation 9 passe à l'extérieur du réservoir 1 immédiatement au-dessus du seuil 4 et après introduction du venturi 8 dans la poche 2 sous l'effet de l'obturation de l'ouverture 14 du réservoir 1 par le bouchon 10, ledit venturi vient automatiquement se placer en vis-à-vis de la pipette 9b de la canalisation 9 pour réaliser le raccordement, de sorte qu'ainsi une liaison amovible s'établit avantageusement au moment de l'équipement du réservoir 1 de ses différents composants. In other words, the pipe 9 passes outside the tank 1 immediately above the threshold 4 and after introduction of the venturi 8 into the pocket 2 under the effect of the closure of the opening 14 of the tank 1 by the plug 10, said venturi is automatically placed opposite the pipette 9b of the pipe 9 to make the connection, so that thus a removable connection is advantageously established when equipping the tank 1 of its different components.
Plus précisément, la liaison entre la canalisation 9 et le venturi 8 est réalisée de la façon suivante, en se reportant plus particulièrement à la figure 4. More specifically, the connection between the pipe 9 and the venturi 8 is carried out as follows, with particular reference to FIG. 4.
Le corps du venturi 8 possède une ouverture circulaire latérale orientée à 45"C vers le bas par rapport à l'axe X-X' de la conduite 6 de retour du carburant au réservoir 1. Cette ouverture 15 est munie d'un joint à lèvres 16 assurant la liaison étanche entre l'ouverture 15 et l'extrémité débouchante ou pipette 9b de la canalisation 9 traversant la paroi 2a du réservoir 1. The body of the venturi 8 has a lateral circular opening oriented at 45 "C downward relative to the axis XX 'of the line 6 for returning fuel to the tank 1. This opening 15 is provided with a lip seal 16 ensuring the sealed connection between the opening 15 and the through end or pipette 9b of the pipe 9 passing through the wall 2a of the tank 1.
L'extrémité débouchante 9b de la canalisation 9 comporte une collerette ou analogue 17 située dans un plan formant un angle de 45"C par rapport à l'axe
Y-Y' de ladite extrémité débouchante ou pipette 9b.The open end 9b of the pipe 9 comprises a flange or the like 17 situated in a plane forming an angle of 45 "C relative to the axis
YY 'of said through end or pipette 9b.
On obtiendra donc ainsi, après insertion du venturi 8 dans le réservoir une liaison étanche et automatique entre ledit venturi et la canalisation 9 lors du vissage de l'écrou 12. Thus, after insertion of the venturi 8 into the reservoir, a tight and automatic connection will be obtained between said venturi and the pipe 9 when the nut 12 is screwed.
On a montré en 30 sur les figures 4 et 5 des moyens d'indexage assurant la coïncidence entre l'ouverture latérale 15 du venturi 8 et l'extrémité débouchante 9b de la canalisation 9 lors du vissage du bouchon 10 sur l'ouverture 14 de la poche principale 2. We have shown at 30 in FIGS. 4 and 5 indexing means ensuring the coincidence between the lateral opening 15 of the venturi 8 and the through end 9b of the pipe 9 when the plug 10 is screwed onto the opening 14 of the main pocket 2.
Ces moyens sont constitués par une jupe circulaire 18 solidaire du couvercle 1 1 et munie d'une encoche repérée en 19 et bien visible sur la figure 5. These means consist of a circular skirt 18 secured to the cover 11 and provided with a notch marked at 19 and clearly visible in FIG. 5.
Cette encoche 19 peut recevoir un doigt ou analogue 20 solidaire de la paroi latérale 2a de la poche principale 2 du réservoir 1. On voit en 19a sur la figure 5 que l'encoche est évasée dans sa partie débouchante, pour guider et faciliter l'insertion du doigt 20. This notch 19 can receive a finger or the like 20 secured to the side wall 2a of the main pocket 2 of the reservoir 1. It can be seen in 19a in FIG. 5 that the notch is flared in its open part, to guide and facilitate the finger insertion 20.
Ainsi, lors du montage du bouchon 10, l'encoche 19 coopère avec le doigt 20 pour n'autoriser le montage du couvercle 1 1 que dans la seule orientation assurant la coïncidence entre le joint à lèvres 16 et la collerette 17 appartenant à la canalisation 9. Thus, during the mounting of the plug 10, the notch 19 cooperates with the finger 20 so as to authorize the mounting of the cover 1 1 only in the only orientation ensuring the coincidence between the lip seal 16 and the flange 17 belonging to the pipe. 9.
On remarquera encore ici que le doigt 20 est, suivant un mode de réalisation préféré, soudé sur la paroi 2a avec une position angulaire précise par rapport à la position de la pipette 9b sur ladite paroi. Ce doigt 20 est représenté sur la figure 4 dans le plan de la pipette 9b, mais, en réalité, il est décalé angulairement pour permettre le passage, dans un mouvement de descente vertical à travers l'ouverture 14 du réservoir, du venturi 8 avec son joint associé 16. It will also be noted here that the finger 20 is, according to a preferred embodiment, welded to the wall 2a with a precise angular position relative to the position of the pipette 9b on said wall. This finger 20 is shown in FIG. 4 in the plane of the pipette 9b, but, in reality, it is angularly offset to allow the passage, in a vertical downward movement through the opening 14 of the reservoir, of the venturi 8 with its associated seal 16.
On a donc réalisé suivant l'invention un dispositif de transfert de carburant depuis une poche annexe à la poche principale d'un réservoir de carburant, qui donne satisfaction tant avec de l'essence qu'avec du gazole puisqu'il permettra d'obtenir une dépression toujours suffisante pour aspirer le carburant de la poche annexe en vue d'alimenter la poche principale. A fuel transfer device has therefore been produced according to the invention from a pocket annexed to the main pocket of a fuel tank, which is satisfactory both with petrol and with diesel since it will make it possible to obtain a vacuum always sufficient to draw fuel from the annex pocket in order to supply the main pocket.
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.
Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit. On the contrary, the invention includes all the technical equivalents of the means described and their combinations if these are carried out according to the spirit.
