Also the rapid increase in pressure, determined by one of the system's pressure sensors or the detection of the Movement of the hydraulic oil can cause the switching valve 23 to remain open, whereby then the essentially free pushing of the hydraulic oil from one Work room 4, 5 in the other and thus largely from hydraulic influence free movement of door 1 is enabled.
