The invention relates to a device for actuating a multiplate clutch (B) in a transmission, composed of an actuating-piston/cylinder arrangement with rotational pressure compensation, the actuating piston (6) of which actuating-piston/cylinder arrangement is assigned a pressure chamber (4) for a pressure medium liquid for generating the actuating force, and in which actuating-piston/cylinder arrangement is provided a pressure compensating chamber (26) in which pressure medium liquid generates a compensation force on the actuating piston (6) as a result of centrifugal force, which compensation force is aligned counter to the actuating direction of the actuating piston (6), wherein the pressure chamber (4) and the pressure compensating chamber (26) have in each case one inflow line (9, 21) for pressure medium liquid. For structural simplification of said device and in order to reduce costs, it is provided that the pressure compensating chamber (26) is arranged entirely with a radial spacing to the pressure chamber (4), and that the pressure compensating chamber (28) is delimited by a plate carrier (1), which carries inner plates, of the multiplate clutch (B) and by the actuating piston (6), and that the pressure compensating chamber (26) is arranged radially above a flow duct (25) which leads axially through the plate carrier (1) which carries inner plates (13). |
