Abstract
The first chamber (15) of the actuator cylinder adjacent to the large side of the differential piston (2) can be connected to a pressure-medium source via an inflow valve (24) and an inflow line. In addition, this chamber (15) can be connected to a pressure-medium trough via an outflow valve (26) and an outflow line (27). The second chamber (16) adjacent to the small side of the differential piston (2) is connected to the inflow side of the inflow valve (24) via an always fully open cross-section of a line (38). In the area of the inflow line (25) and the line (38), a non-return member (39) is arranged between the inflow valve (24) and the second chamber (16) on the one hand and the pressure-medium source on the other hand, which non- return member (39) permits flow only from the pressure-medium source to the inflow line (25). The inflow valve (24) and the outflow valve (26) are connected to the first chamber (15) exclusively via a common, preferably adjustable restrictor device (21).
