CA 2381462

The invention relates to a filler neck for the fuel tank of a motor vehicle. The inventive filler neck comprises a housing (12, 14) which has an outer closure (30) that can pivot between a closed and opened position and which has a second closure element (50) that is accommodated inside the housing. Said second closure element is interactively connected to a ventilating valve (16) which, in order to equalize pressure, automatically opens in the instance of excess pressure inside the fuel tank and opens when inserting the dispensing nozzle (100), said dispensing nozzle causing the closure element (50) to swivel open. The inventive filler neck is characterized by a lever (1) which is pivotally mounted on the housing (12). Said lever is actuated by the dispensing nozzle (100) when the same is inserted, and opens the ventilating valve (16) before the dispensing nozzle (100) causes the second closure element (50) to swivel open.

L'invention concerne une tubulure de remplissage pour le réservoir de carburant d'un véhicule automobile, comportant un boîtier (12, 14) qui présente une fermeture extérieure (30) pouvant pivoter entre une position fermée et une position ouverte, ainsi qu'un deuxième élément de fermeture (50) logé à l'intérieur du boîtier et coopérant avec une soupape de décharge (16). Cette liaison entre le deuxième élément de fermeture et la soupape de décharge provoque l'ouverture automatique de cette dernière en cas de surpression dans le réservoir de carburant, afin de réaliser une compensation de pression, et lors de l'introduction d'un pistolet (100) de pompe de distribution de carburant, qui ouvre l'élément de fermeture (50). L'invention est caractérisée en ce qu'un levier (1) est monté de manière à pouvoir pivoter sur le boîtier (12). Ce levier, actionné par le pistolet (100) au moment de son introduction dans la tubulure, ouvre la soupape de décharge (16) avant même l'ouverture du deuxième élément de fermeture (50) par le pistolet (100).
