Patent ID: 7954615

Claim:
A device for actuating a disk clutch (B) in a transmission, the device comprising: a piston-cylinder arrangement having an actuating piston ( 6 ) that is actuated in a first axial direction as a pressure medium liquid passes through a first supply line ( 9 ) and enters a pressure chamber ( 4 ), which is associated with the actuating piston; a pressure compensation chamber ( 26 ) having a second supply line ( 21 ) through which centrifugal force pressure medium fluid flows and enters the pressure compensation chamber ( 26 ) for producing a compensating force, which is applied on the actuating piston ( 6 ) to push the actuating piston ( 6 ) in a second axial direction opposite the first axial direction; and the pressure compensation chamber ( 26 ) being radially located completely over the pressure chamber ( 4 ) and being separated therefrom a radial distance, the pressure compensation chamber ( 26 ) being delimited by the actuating piston ( 6 ) and a disk carrier ( 1 ), which supports inner disks ( 13 ) of the disk clutch (B), the pressure compensation chamber ( 26 ) being radially located above a flow channel ( 25 ) that axially extends through the disk carrier ( 1 ) and delimits a radial interior of the pressure compensation chamber ( 26 ).
