TANKVERSCHLUSS, INSBESONDERE FUER DEN TANK EINES KRAFTFAHRZEUGS.

摘要

A tank closure mechanism, especially for a fuel tank of an automotive vehicle, with a locking tube pertaining to the cap proper and including a pressure plate and a gasket. The locking tube is rotatable by rotating the cap housing during locking operation of the cap by a latch of a lock cylinder but remains stationary after an unlocking during a rotation of the cap housing. A clamping ring exerting a tightening clamp is rotatable together with the locking tube. A compression spring of a bayonet catch presses against the clamping ring with the spring being supported on the cap and the pressure plate. The locking tube and pressure plate are fashioned so as to be bi-partite and the pressure plate extends over the locking tube with a sliding fit or the like.
