Pusher device i.e. push-push device for moving e.g. fuel trap's flap, used to transfer fuel towards motor vehicle, has blocking ring moving between blocking position and release position in which ring authorizes displacement of push rod

摘要

The device (10) has a bushing (17) fixed in rotation with respect to a housing (11) according to a thrust direction (Y10) and comprising a central opening to guide a push rod between retracted and extended positions. A blocking ring (19) is movable with respect to the housing, the push rod and with respect to the bushing. The blocking ring is movable between a blocking position, in which the blocking ring blocks the push rod in the retracted position and a release position in which the ring authorizes the displacement of the push rod till the extended position. An independent claim is also included for a fuel or power trap for transferring fuel or power toward a motor vehicle.
