Abstract
The invention relates to a hydraulic actuating device for a movable component of a vehicle, in particular a closure element for closing an opening in a vehicle body, such as for example a movable roof, such as a folding roof or a retractable hard top. The hydraulic actuating device according to the invention has hydraulic actuating means for driving a first control valve assembly, which hydraulic actuating means comprise at least one hydraulic control connection which is in communication with a second connection of a hydraulic actuator, and which hydraulic actuating means are designed to ensure that, when a first hydraulic pressure is present at the second connection, which first hydraulic pressure is the consequence of a connection being formed between the second connection and a pressure port of a pump, a first connection of the actuator is connected to a reservoir, and that when a second hydraulic pressure is present at the second connection, which second hydraulic pressure is the consequence of a connection being formed between the second connection and the reservoir, the first connection is connected to the pressure port of the pump.
