ABSTRACT:
A self-closing fuel tank closing device mountable on a fuel tank filler pipe includes a filler cap which is tensioned in the direction of a sealing seat and is rotatable in the direction of the interior of the filler pipe. The filler cap is carried by a swivel arm supported at one end thereof. In order to achieve a small construction and degressive torque characteristics on opening the filler cap, it is provided that the free end of the swivel arm is supported on a supporting surface which runs approximately perpendicular to the longitudinal axis of the fuel tank closing device. The device further includes a clamping device which pretensions the filler cap in the direction of the sealing seat and is mounted on the swivel arm in the region between the free end and the filler cap.
