ABSTRACT:
A device for actuating a disk clutch (B) in a transmission, which consists of an actuating piston-cylinder arrangement with rotation pressure compensation, whose actuating piston (6) is associated with a pressure chamber (4) for a pressure medium fluid to produce the actuating force, and in which a pressure compensation chamber (26) is provided, in which by virtue of centrifugal action a pressure medium fluid produces on the actuating piston a compensation force directed in opposition to the actuation direction of the actuating piston, the pressure chamber and the pressure compensation chamber each having a delivery line (9, 21) for pressure medium fluid. To simplify the structure of this device and reduce costs, the pressure compensation chamber is arranged completely a radial distance away from the pressure chamber, the pressure compensation chamber is delimited by a disk carrier (1) of the disk clutch that carries inner disks and by the actuating piston and the pressure compensation chamber is arranged radially above a flow channel (25) leading through the disk carrier that carries inner disks (13).
