In a venting device for a fuel tankof a motor vehicle having a filler neck and a venting valve, a circulation pipe is provided which, due to the suction jet effect when refueling circulates gas from the fuel tank back into the tank with the fuel so as to prevent an excessive inflow of fresh air, and which includes a venting pipe extending between venting valveand a filter for discharging excess gases through a filter in order to prevent the escape of fuel vapors into the environment.

Venting device for fuel tanks

In a fuel tank installation including a fuel tank with an expansion volume, a filler neck connected to the fuel tank below a maximum fuel level of the tank for refueling the tank, a fill vent line for venting the fuel tank during refueling and an operating vent line for venting an expansion volume of the tank, the operating vent line extends within the fuel tank from the expansion volume of the fuel tank to a central penetration location and, at the central penetration location, through the wall of the tank together with the fill vent line.
