Patent ID: 7147018

Claim:
A filling fitting formation for a fuel tank of a motor vehicle having an automatic tank closure, the filling fitting formation comprising: a fuel tank carrier with a transverse wall affixed thereto having an inlet opening therethrough for penetration of a fuel nozzle; a closure cover pivotally carried on an axle disposed transverse to a central longitudinal axis of the inlet opening, a sealing element disposed on the closure cover coacting with a sealing element seat, which is formed by an opening rim of the transverse wall; a closure component disposed proximate the closure cover, the closure component in a closed state of the closure cover penetrating the inlet opening with an axial section having a plurality of closure elements projecting radially therefrom; and a closure ring disposed above the transverse wall the closure ring defining an inner circumferential section depending inwardly to coact with the closure elements, such that in a first rotational station of the closure ring, the inner circumferential section escapes engagement with the closure elements and in a second rotational station, the inner circumferential section contacts the closure elements from below, whereby the sealing element is pressed by an axial acting force on an underside of the transverse wall, the axial acting force generated by a spring element disposed in a force transmission path between the sealing element of the closure cover and the transverse wall.
