Abstract
A clutch actuator controlled by a pressure medium, in particular for a compressor clutch of a commercial vehicle has an actuating piston displaceably disposed in a housing in an axial direction. An end of the actuating piston is supported in the axial direction on an elastic membrane, sealing a first region of the housing off from a second region of the housing. The elastic membrane includes a raised area on the side opposite the actuating piston. The clutch actuator can be used in a compressor clutch for a commercial vehicle.
