A cam and a normally closed control valve actuated by the cam and controlling the fluid connection between the canister and the interior of the fuel tank are arranged in the valve housing. The cam shaft of the cam is mechanically connected to the rotary shaft of the closure valve. When the closure valve is opened by the fuel pump nozzle, the control valve is opened by the cam to feed the fuel vapor in the fuel tank into the canister.
