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.
Claims16
A pressure medium-controlled clutch actuator, comprising:
- a housing;
- an actuating piston arrangeable to move in an axial direction in the housing;
- an elastic diaphragm having a rim, the elastic diaphragm supporting one end of the actuating piston in the axial direction, the elastic diaphragm sealing-off a first area of the housing from a second area of the-housing, wherein
- the elastic diaphragm includes a raised area that extends in a direction away from the actuating piston distant from the rim;
- the raised area is formed by a region of the elastic diaphragm with increased thickness, as compared to a rest of the elastic diaphragm;
- said raised area rests in an assigned depression of the housing in one operating position of the clutch actuator such that the raised area completely fills the assigned depression;
- and
- said raised area in conjunction with said assigned depression of the housing achieve a biasing of the actuating piston in the axial direction when the clutch actuator is in said one operating position.
