Abstract

L'invention concerne un ensemble formant réservoir, destiné à un véhicule, comprenant un réservoir de carburant (2), un conduit de carburant (4) destiné à acheminer le carburant du réservoir de carburant à un moteur à combustion interne (3), une soupape de sécurité (5) placée dans le conduit de carburant dans le réservoir de carburant et comportant une entrée (7) reliée au carburant dans le réservoir de carburant, une sortie (8) pouvant être reliée au moteur à combustion interne, un raccord de commande (9) sur lequel la pression du réservoir de carburant appuie, et un corps de fermeture (11) pouvant être déplacé entre une position ouverte (12) et une position fermée (13). Dans la position ouverte, l'entrée est reliée à la sortie et, dans la position fermée, la sortie est séparée de l'entrée. Lorsque le corps de fermeture est dans la position ouverte, une pression de conduit est présente dans la zone située entre l'entrée et la sortie. De plus, le corps de fermeture peut être déplacé dans la position fermée au moyen de la pression de réservoir au niveau du raccord de commande, en s'opposant à la pression de conduit.
