Driving device for a closing arrangement of a vehicle-tank filler neck, having a housing (,), an input shaft (,), which is intended for the connection of a drive motor (,), an output shaft (,), which is intended for driving the closing arrangement, and a gear mechanism (,) which is arranged in the housing (,) and acts between the input shaft (,) and the output shaft (,), the gear mechanism (,) being a worm wheel/worm mechanism with a self-locking action in the direction from the output shaft to the input shaft, a clutch (,) being arranged between the gear mechanism (,) and the output shaft (,), and a manual actuating arrangement (,) with a predetermined actuating travel being provided which, over a first part (FIGS.,) of the actuating travel, moves the clutch (,) into the disengaged position and, over a second part (FIGS.,) of the actuating travel, drives the output shaft (,).

Driving device for a vehicle-tank filler neck

Valve mechanism for controlling the fluid flows when refueling a fuel tank provided with a filler neck, having: a housing in which there are constructed a first opening, a second opening and a third opening; a valve member which is mounted movably in the housing between a first and a second position and has at least one sealing surface; a valve seat which in the housing is arranged between the openings and cooperates with the sealing surface(s) of the valve member in order, in the first position, to set up a first fluid connection between the first opening and the second opening, and a second fluid connection between the second opening and the third opening, and, in the second position, to interrupt the first and the second fluid connections; and a third fluid connection which is constructed in the housing between the second opening and the third opening and has a higher flow resistance than the second fluid connection.
