Abstract
A fuel tank closure for closing off a filling channel has a closure part that can be moved between a closed position in which an opening of the filling channel is tightly sealed, and an open position, in which the filling channel is released, in order for a fuel tank to be filled. The closure part is driven by a drive unit that has a motor.
Claims26
A fuel tank closure for closing off a filling channel comprising:
- (a) a closure part movable between a closed position in which an opening of the filling channel is sealed and an open position in which the filling channel is released in order to fill a fuel tank, said closure part sitting on an edge of the opening to form a seal in the closed position, and being pivoted laterally relative to the filling channel in the open position;
- (b) a drive unit comprising a motor driving said closure part;
- and
- (c) a compulsory guide guiding said closure part, lifting said closure part off the edge of the opening in an approximately axial direction during opening of the filling channel, and subsequently pivoting said closure part laterally about a pivot axis lying transverse to a longitudinal direction of the filling channel;
- wherein said closure part comprises a first edge segment and a second edge segment lying opposite said first edge segment, and said compulsory guide has means for fixing said first edge segment in place, in articulated manner near a position in which said closure part assumes the closed position, while allowing pivoting of said second edge segment about said first edge segment during opening and closing;
- wherein said compulsory guide has an articulation part joined to said closure part on a first side, and mounted on a housing part, on a second side;
- and
- wherein said articulation part is mounted in a hinge arranged on said housing part on the second side, and in at least one bore arranged on said closure part on the first side, said hinge and said at least one bore having parallel axes.

- (b) a drive unit comprising a motor driving said closure part;
- (c) a force absorption part arranged on at least one of the struts on which forces in an axial direction, for closing and opening the fuel tank closure, can be exerted;
- and
- (d) an axially movable thrust ring coupled to said force absorption part;
- wherein said drive unit drives a threaded pipe piece, said pipe piece being rotatable about a longitudinal axis of said pipe piece, said pipe piece surrounding said thrust ring and interacting with a thread of said thrust ring in order to move said thrust ring axially.
