摘要：The invention relates to a hydraulic actuating device for a movable componentof a vehicle, in particular a closure element for closing an opening in a vehicle body, suchas for example a movable roof, such as a folding roof or a retractable hard top. Thehydraulic actuating device according to the invention has hydraulic actuating means fordriving a first control valve assembly (18), which hydraulic actuating means comprise atleast one hydraulic control connection which is in communication with a second
connection of a hydraulic actuator, and which hydraulic actuating means are designed toensure that, when a first hydraulic pressure is present at the second connection (16),which first hydraulic pressure is the consequence of a connection being formed betweenthe second connection and a pressure port (11) of a pump (10), a first connection (15) ofthe actuator is connected to a reservoir (12), and that when a second hydraulic pressure ispresent at the second connection (16), which second hydraulic pressure is theconsequence of a connection being formed between the second connection and thereservoir, the first connection (15) is connected to the pressure port (11) of the pump(10).
