Abstract

The fuel tank for a car is moulded of plastics and has the underside moulded in one piece with a restricted throat (5) leading to a small captive space (4) from which the fuel line is taken. The captive space provides a secure fuel feed no matter how low the fuel level is in the main tank (1), or when the vehicle is on a slope. The restriction may be formed during the main moulding process and requires no additional fittings to the tank. The captive space provides uninterrupted fuel supply also when the vehicle is being driven around corners or over rough ground.

Description

L'invention concerne un réservoir de carburant en matière plastique pour véhicule, comportant, formant corps avec lui en dehors de son espace intérieur un réservoir de stabilisation dont la limite avec le réservoir principal est constituée par un étranglement et qui se raccorde au réservoir principal par une ouverture d'alimentation. The invention relates to a plastic fuel tank for a vehicle, comprising, forming a body with it outside its internal space, a stabilization tank whose limit with the main tank is constituted by a constriction and which is connected to the main tank by a feed opening.

Lors d'une accélération, d'un freinage ou de franchåssement d'une courbe, les véhicules sont soumis à des efforts d'accélération qui, dans le réservoir, éloignent le carburant de la zone de l'orifice d'alimentation (en particulier lorsque le niveau de carburant est bas) ; le moteur du véhicule n'est plus alors alimenté en carburant et peut s'arrêter. Pour éviter cet incident, les réservoirs de carburant sont équipés d'enceintes de stabilisation. When accelerating, braking or crossing a curve, vehicles are subjected to acceleration forces which, in the tank, move the fuel away from the supply port area (in particular when the fuel level is low); the vehicle engine is then no longer supplied with fuel and may stop. To avoid this incident, the fuel tanks are equipped with stabilization chambers.

On cannait un réservoir de carburant du te cité au début (DE - AS 1 455 496) qui présente une section aplatie et sur lequel l'enceinte de stabilisation est formée, au milieu du réservoir et à partir de lui, par deux empreintes en creux annulaires réalisées l'une en face de l'autre respectivement dans la face supérieure et dans la face inférieure du réservoir et soudées l'une à l'autre par leurs faces frontales. La hauteur de l'enceinte de stabilisation correspond donc à peu près à celle du réservoir. A fuel tank from the te mentioned at the beginning (DE - AS 1 455 496) was canned which has a flattened section and on which the stabilization enclosure is formed, in the middle of the tank and from it, by two hollow imprints annulars made one opposite the other respectively in the upper face and in the lower face of the tank and welded to each other by their front faces. The height of the stabilization enclosure therefore corresponds approximately to that of the tank.

Indépendamment du fait que sur cette construction conque, une fraction importante du volume du réservoir est sacrifiée à la réalisation des empreintes en creux et de l'enceinte de stabilisation il est nécessaire de prévoir sous le fond du réservoir une cana lisation de carburant pour le raccordenent de l'encein- te au réservoir. Independently of the fact that on this conch construction, a significant fraction of the volume of the tank is sacrificed for the production of hollow impressions and of the stabilization enclosure, it is necessary to provide under the bottom of the tank a fuel pipe for the connection. from the enclosure to the tank.

Au plan de la technique de fabrication et du montage, cette canalisation occasionne des frais supplémentaires et, par ailleurs, se trouve particu lièrement exposée en cas d'accident, car elle peut facilement être endommagée, perdre son étanchéité et donner ainsi lieu à une fuite du carburant. In terms of manufacturing and mounting technique, this pipe incurs additional costs and, moreover, is particularly exposed in the event of an accident, since it can easily be damaged, lose its sealing and thus give rise to a leak. fuel.

L'invention a pour but de donner à un réservoir de carburant du type cité au début une conformation telle qu'il offre un bon espace utile tout en demeurant d'une fabrication et d'un montage écono miques.  The object of the invention is to give a fuel tank of the type mentioned at the start a conformation such that it offers good useful space while remaining economical to manufacture and assemble.

Sur un réservoir de la catégorie cité, l'invention résoud ce problème en prévoyant que le réservoir de stabilisation soit formé à partir du réservoir principal et vers le bas et que l'ouverture d'alimentation soit constituée par une ouverture limitée par l'étranglement. Grâce à cette conformation, il est possible de fabriquer en une seule opération le réservoir de carburant et le réservoir de stabilisation en communication permanente avec lui, car par l'ouverture réalisée au voisinage de l'étranglement, l'alimentation en carburant du réservoir de stabilisation est possible sans qu'il soit nécessaire de prévoir à cet effet des canalisations supplémentaires traversant les cloisons.L'ouverture peut etre dimensionnée facilement d'après la profondeur de l'étranglement0
L'invention prévoit également que l'étran- glement se situe à la partie la plus basse du réservoir de carburant pour garantir la pleine utilisation du volume de ce réservoir.On a tank of the cited category, the invention solves this problem by providing that the stabilization tank is formed from the main tank and downwards and that the supply opening consists of an opening limited by the throttle . Thanks to this conformation, it is possible to manufacture in a single operation the fuel tank and the stabilization tank in permanent communication with it, because by the opening made in the vicinity of the constriction, the fuel supply to the stabilization is possible without it being necessary to provide for this purpose additional pipes passing through the partitions. The opening can be dimensioned easily according to the depth of the constriction
The invention also provides that the throttle is located at the lowest part of the fuel tank to guarantee full use of the volume of this tank.

'étranglement peut être prévu au centre du réservoir de carburant ou sur une position excentrée pour que le réservoir de carburant s'adapte de façon simple à l'espace disponible sur les diffÉrents type de véhicules. The throttle can be provided in the center of the fuel tank or in an eccentric position so that the fuel tank simply adapts to the space available on the different types of vehicles.

Un exemple d'exécution de l'invention, décrit plus en détail dans ce qui suit, est représenté sur la figure, qui montre en coupe un réservoir de carburant équipé d'un réservoir de stabilisation. An embodiment of the invention, described in more detail below, is shown in the figure, which shows in section a fuel tank equipped with a stabilization tank.

Le réservoir de carburant 1 en matière plastique partiellement représenté est construit par soufflage. Lors de sa fabrication, une enceinte de stabilisation 4 en communication permanente avec l'espace 3 de stockage du carburant a été réalisée par formage d'une structure en forme de bulle limitée par un étranglement 2. The partially represented plastic fuel tank 1 is constructed by blowing. During its manufacture, a stabilization enclosure 4 in permanent communication with the space 3 for storing the fuel was produced by forming a bubble-shaped structure limited by a constriction 2.

L'étranglement 2 se situe au point le plus bas du réservoir de carburant 1 et limite une ouverture 5 prévue dans la zone de transition entre l1es- pace de stockage 3 et l'enceinte de stabilisation 4o  The constriction 2 is located at the lowest point of the fuel tank 1 and limits an opening 5 provided in the transition zone between the storage space 3 and the stabilization enclosure 4o
