Abstract
A fuel tank for vehicles, particularly motor vehicles, is provided with an operational ventilating system which is composed essentially of a vent outlet arranged in the area of an upper fuel tank wall, of an exterior air feeding and air removing pipe connected to the vent outlet, and of an activated-carbon filter connected behind. To prevent liquid fuel particles from entering the activated-carbon filter by way of the vent outlet, particularly during lateral accelerations, a device is disposed inside the fuel tank in front of the vent outlet, which device partitions off the vent outlet with respect to a direct action of liquid fuel particles.
Claims24
Fuel tank system for vehicles, particularly motor vehicles, comprising:
- an operational ventilating system which is composed essentially of a vent outlet arranged in an area of an upper fuel tank wall,
- an exterior air feeding and air removing pipe connected to the vent outlet, and
- a partitioning device disposed in front of the vent outlet inside the fuel tank which partitions off the vent outlet with respect to a direct action by liquid fuel particles thrown upwards during the driving operation,
- wherein said partitioning device is a receptacle with a plurality of walls spaced from one another and having offset openings thereby forming a labyrinth path from the fuel tank to the vent outlet,
- and wherein said receptacle includes a bottom which slopes downwardly to bottom portions of at least one of said offset openings thereby facilitating flow of any liquid fuel in said receptacle back to the fuel tank.
