- the hydraulic actuator 26 is connected via the second branch 35 and the valve 36 to the second slave cylinder 22, so that the starting clutch 1 1 is modulated.
- the embodiment shown in Figure 4 differs from the embodiment shown in Figure 3 only in that a hydraulic actuator 46 is used, which is designed as a hydraulic pump 48.
- the hydraulic pump 48 can be operated in two opposite directions of flow and is also referred to as a reverse pump.
- the hydraulic pump 48 is driven by an electric motor 49.
- an electric motor 49 In a first
- Flow direction promotes the hydraulic pump 48 hydraulic medium from the hydraulic medium reservoir 28 in one of the two slave cylinder 21,22.
- the hydraulic pump 48 delivers hydraulic medium from one of the slave cylinders 21, 22 into the hydraulic medium reservoir 28.
- the two valves 36 and 38 shown in FIGS. 3 and 4 can advantageously be operated in two stable switching positions.
- the valves 36 and 38 are designed so that they are the largest time shares operated in an energetically favorable de-energized state.
- the valve 38 is advantageously designed as a seat valve in order to minimize the leakage during operation of the valve device 39.
- valve device 29, 39 is advantageously integrated in a housing in the hydraulic actuating device 26, 46. This provides the advantage that additional housing for the valve devices and connecting parts can be omitted.
