A device for actuating a plurality of hydraulic control cylinders having a pressure regulating valve with a first and a second pressure regulating output, a first selector valve connected downline from the pressure regulating outputs, a second selector valve connected downline from the first selector valve, having a plurality of individual pressure outputs, where the second pressure regulating output is optionally assignable through the first and second selector valves to one of the individual pressure outputs, and the particular individual pressure outputs that are not assigned to the second pressure regulating output are assignable to the first pressure regulating output.

Device for actuating a plurality of hydraulic control cylinders

A dual clutch transmission which has a first clutch, actuated by a first hydraulic cylinder, a second clutch, actuated by a second hydraulic cylinder, shift devices for shifting gears, which are actuated by respective hydraulically operated cylinders, and a hydraulic energy source for supplying the hydraulic cylinders and the hydraulically operated cylinders with hydraulic energy. The hydraulic energy source has a first pump, a second pump and an electric drive driving the second pump.
