Abstract

An arrangement for the hydraulic actuation of a cover flap (1) on a vehicle (2) has a working cylinder (3), the working spaces (8, 9) of which each have a check valve (10, 11) with one side of a switchable pressure source (12). keep in touch. The two check valves (10, 11) have a mutual unlocking device and the two working spaces (8, 9) are connected in parallel to the check valves (10, 11) via a preload valve (15). In order to enable a safe emergency actuation of the cover flap (1) in a simple manner, an emergency valve (17) which shuts off the tank (16) and which is shut off during normal operation of the arrangement is switched on between the piston-side working chamber (8) and the unlockable check valve (10).
