Abstract

The present invention relates to a nozzle for filling a tank. This nozzle comprises an end 1 which can be shut off in a sealed manner by means of a cap 2, whilst upstream from the cap there is provided a sleeve 3 made from a flexible material mounted between the nozzle and a wall 4 of the bodywork of a vehicle, and which comprises, in the region of its part 3b securely fastened to the nozzle, a collar 9 forming a seal for the cap. The nozzle of the invention allows the tank of a motor vehicle to be filled with fuel.

Description

La présente invention a essentiellement pour objet une tubulure de remplissage d'un réservoir de carburant. The present invention essentially relates to a nozzle for filling a fuel tank.

Elle vise également un véhicule automobile équipé de cette tubulure. It also relates to a motor vehicle equipped with this tubing.

On sait que les tubulures de remplissage de réservoir sont généralement obturées par un bouchon qui est muni d'un joint assurant une bonne étanchéité au niveau de l'extrémité de la tubulure. It is known that the tank filling pipes are generally closed by a plug which is provided with a seal ensuring a good seal at the end of the pipe.

Toutefois, l'extrémité de la tubulure est soumise à des chocs à chaque fois qu'on y introduit un bec de remplissage pour effectuer le remplissage en carburant du véhicule. Comme on le comprend, ces chocs répétés déforment peu à peu l'extrémité débouchante de la tubulure et l'étanchéité est alors moins bien réalisée au niveau du joint du bouchon. However, the end of the tube is subjected to shocks each time a filling spout is introduced therein to fill the vehicle with fuel. As can be understood, these repeated shocks gradually deform the open end of the tubing and the seal is then less well achieved at the seal of the plug.

La présente invention a pour but de remédier à cet inconvénient en proposant une tubulure perfectionnée Fcur véhicule, qui non seulement demeure parfaitement étanche lorsqu'elle est obturée par le bouchon, mais absorbe les dispersions de positions qui sont inévitables, entre la tubulure et la paroi de la carrosserie du véhicule. The object of the present invention is to remedy this drawback by proposing an improved vehicle Fcur tubing, which not only remains perfectly sealed when it is closed by the plug, but also absorbs the dispersions of positions which are inevitable, between the tubing and the wall. of the vehicle body.

A cet effet, l'invention a pour objet une tubulure de remplissage d'un réservoir de carburant, en particulier pour véhicule automobile, et du type comprenant une extrémité pourvue de moyens susceptibles de coopérer avec un bouchon pour obturer la tubulure, caractérisée en ce qu'en amont desdits moyens, est prévue une manchette en matière flexible montée entre la tubulure et une paroi de la carrosserie du véhicule, et qui comporte, au niveau de sa partie solidaire de la tubulure, une collerette formant joint d'étanchéité pour le bouchon.  To this end, the subject of the invention is a tube for filling a fuel tank, in particular for a motor vehicle, and of the type comprising an end provided with means capable of cooperating with a plug for closing the tube, characterized in that that upstream of said means, there is provided a flexible material cuff mounted between the tubing and a wall of the vehicle body, and which comprises, at its part integral with the tubing, a collar forming a seal for the plug.

Ainsi, la manchette possède la double fonction d'étanchéité de l'extrémité de la tubulure vis-à-vis du bouchon, et d'absorption des dispersions de position de ladite tubulure par rapport à la paroi de la carrosserie du véhicule. Thus, the cuff has the double function of sealing the end of the tubing with respect to the plug, and of absorbing positional dispersions of said tubing relative to the wall of the vehicle body.

On précisera encore ici que la manchette précitée est montée sur un embout solidaire de l'extrémité de la tubulure et recevant le bouchon. It will also be specified here that the aforementioned cuff is mounted on an endpiece integral with the end of the tubing and receiving the plug.

Selon encore une autre caractéristique de l'invention, la collerette prévue sur la manchette est susceptible de venir en engagement étanche avec une jupe conique du bouchon. According to yet another characteristic of the invention, the collar provided on the cuff is capable of coming into sealed engagement with a conical skirt of the plug.

On ajoutera encore ici que la manchette est réalisée en un matériau résistant aux hydrocarbures, tel que par exemple un élastomère type nitrile. It will also be added here that the cuff is made of a material resistant to hydrocarbons, such as for example an elastomer of the nitrile type.

Mais d'autres caractéristiques et avantages de l'invention apparattront mieux dans la description détaillée qui suit et se réfère au dessin unique annexé, donné uniquement à titre d'exemple, et montrant, en coupe longitudinale, une tubulure de remplissage conforme aux principes de l'invention. However, other characteristics and advantages of the invention will appear more clearly in the detailed description which follows and refers to the single appended drawing, given solely by way of example, and showing, in longitudinal section, a filling tube conforming to the principles of the invention.

Suivant un exemple de réalisation, et en se reportant à la figure unique annexée, une tubulure T de remplissage selon l'invention est munie sur sa partie d'extrémité 1 recevant un bouchon 2, d'une manchette 3 reliant ladite partie 1 à une paroi 4 de la carrosserie du véhicule. According to an exemplary embodiment, and with reference to the single appended figure, a filling tube T according to the invention is provided on its end part 1 receiving a plug 2, with a cuff 3 connecting said part 1 to a wall 4 of the vehicle body.

Plus précisément, la manchette 3 est montée par sa partie périphérique externe 3a sur le bord 5 d'un orifice formé dans la paroi 4 et ménageant un passage pour l'extrémité de la tubulure 1. More specifically, the cuff 3 is mounted by its external peripheral part 3a on the edge 5 of an orifice formed in the wall 4 and providing a passage for the end of the tube 1.

Quant à la périphérie interne 3b de la manchette 3, on voit qu'elle est montée sur un embout 6 solidaire de l'extrémité 1 de la tubulure. Cet embout 6 comporte un filetage externe 7 coopérant avec un filetage correspondant 8 réalisé dans le bouchon 2 pour permettre ainsi l'obturation de la tubulure. As for the internal periphery 3b of the cuff 3, it can be seen that it is mounted on a nozzle 6 secured to the end 1 of the tubing. This nozzle 6 has an external thread 7 cooperating with a corresponding thread 8 made in the plug 2 to thereby allow the closure of the tubing.

La manchette 3 comporte une collerette 9 qui, comme on le voit bien sur la figure, forme une lèvre annulaire d'étanchéité sur laquelle peut prendre appui de manière étanche une jupe conique 10 du bouchon 2. The cuff 3 comprises a flange 9 which, as can be seen in the figure, forms an annular sealing lip on which a conical skirt 10 of the plug 2 can sealingly bear.

Comme cela est bien connu, la tubulure T débouche dans une cavité 11 fermée par une trappe 12 qui est articulée sur la carrosserie. As is well known, the tube T opens into a cavity 11 closed by a hatch 12 which is articulated on the body.

L'embout 6 comporte une partie annulaire 13 qui vient prendre appui contre une doublure d'aile 14. Cette doublure 14 ainsi que la doublure de coffre montrée en 15 isolent le milieu intérieur 16 du coffre à bagages du milieu extérieur 17. The endpiece 6 comprises an annular part 13 which comes to bear against a wing lining 14. This lining 14 as well as the boot lining shown at 15 isolate the interior environment 16 of the luggage compartment from the exterior environment 17.

La tubulure 1 est bien entendu reliée à un réservoir repéré en R. The tubing 1 is of course connected to a tank identified at R.

La tubulure qui vient d'etre décrite présente de nombreux avantages. The tubing which has just been described has many advantages.

Elle est simple à réaliser étant donné que la manchette 3 et le joint 9 d'étanchéité du bouchon ne constituent qu'une seule pièce. Il en résulte que la réalisation du bouchon, sans joint à assembler, est simplifiée. It is simple to produce since the cuff 3 and the seal 9 of the plug constitute only one piece. As a result, the production of the plug, without a joint to be assembled, is simplified.

Par ailleurs, l'étanchéité n'étant pas réalisée à la partie extrême de la tubulure 1, mais en retrait par rapport à celle-ci, les chocs qui peuvent se produire sur cette partie extrême restent sans influence sur la qualité de l'étanchéité au niveau du joint 9. Furthermore, since the seal is not produced at the end part of the pipe 1, but recessed relative to the latter, the shocks which may occur on this end part remain without influence on the quality of the seal. at the joint 9.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qurà 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.

C'est ainsi que le matériau pour réaliser la manchette flexible peut être un élastomère nitrile ou tout autre type de matériau approprié. Egalement, le bouchon pourrait ne pas être vissé sur l'embout, et on pourrait utiliser par exemple un bouchon du type à baïonnette coopérant avec une rampe hélicodale réalisée sur une collerette interne, à l'extrémité de la tubulure. Thus, the material for making the flexible cuff can be a nitrile elastomer or any other type of suitable material. Also, the plug could not be screwed onto the end piece, and one could for example use a plug of the bayonet type cooperating with a helical ramp produced on an internal flange, at the end of the tubing.

De même, l'embout 6 pourrait être supprimé et la manchette 3 directement portée par la tubulure 1. La collerette 9 formant joint pourrait aussi comporter une ou plusieurs lèvres orientées dans différentes directions, sans pour cela sortir du cadre de l'invention.Likewise, the end piece 6 could be eliminated and the cuff 3 directly carried by the tube 1. The flange 9 forming a seal could also include one or more lips oriented in different directions, without thereby departing from the scope of the invention.

C'est dire que l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit.  This means that the invention includes all the technical equivalents of the means described, as well as their combinations if these are carried out according to the spirit.
