ABSTRACT:
In a venting device for a fuel tank1of 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 valve2and a filter for discharging excess gases through a filter in order to prevent the escape of fuel vapors into the environment.
