Abstract
A closure of a tank of a motor vehicle for closing a filler neck gas- and fluid-tight, having a closure fastened to a flap, the flap being fastened to a vehicle body of the motor vehicle such that it is movable into an open or closed position, the closure including a seal, which causes the closure to close against the filler neck. The tank closure should be easy for a user to handle and have a relatively simple design and be economical to manufacture. This is achieved in that the seal is electromechanically or pneumatically adjustable with the aid of an actuator.
Claims9
A closure component for a tank of a motor vehicle for closing a filler neck gas- and fluid-tight, the closure component comprising:
- a closure fastened to a flap, the flap being fastened to a vehicle body of the motor vehicle such that the flap and the closure are movable into an open position or a closed position, a seal, which causes the closure to be retained against the filler neck when the closure is in the closed position, wherein the seal is electromechanically or pneumatically adjustable with the aid of an actuator, wherein the seal has an annular, ring shape with a central opening, and wherein, when the closure is in the closed position, a portion of the filler neck is inserted through the central opening of the seal, wherein the adjustment of the seal takes place by changing a cross section of the filler neck, such that when the closure is in the open position, the cross section of the filler neck is smaller than when the closure is in the closed position, wherein the seal remains connected to the filler neck when the closure is in the open state.
