The housing has a base part and a cover part. An annular pressure chamber is disposed within the housing. The pressure chamber is axially delimited by a piston which is movable in the axial direction. The pressure chamber is radially delimited by the outer walls of the housing and by an inner ring which surrounds an inner wall of the housing. The inner wall has an inner wall portion. In the housing, a disc element is disposed on the piston top face, which faces away from the pressure chamber and is axially oriented. The piston top face is seated against or fastened to the disc element. The inner wall portion is protrudingly located in a cover part or in a base part of the housing.
