Abstract
The housing of the slave cylinder in an apparatus for actuating a friction clutch between the engine and the input shaft of the change-speed transmission in the power train of a motor vehicle has a one-piece metallic or plastic member which is non-rotatably affixed to the transmission case. The annular piston of the slave cylinder carries a clutch release bearing and is surrounded by a wall of the housing; this piston slidably surrounds a deep-drawn metallic guide sleeve which is centered in the transmission case and has a flange secured to a collar of the housing by two or more lugs having mutually inclined portions partially bent around and partially recessed into the collar.

Fluid-operated apparatus for actuating a friction clutch between a prime mover and a rotary component in a case of a change-speed transmission in the power train of a motor vehicle, comprising:
- a slave cylinder including a housing coaxial with the rotary component and borne by the case of the transmission, and a reciprocable annular piston disposed in said housing and surrounded by a wall of the housing;
- a guide sleeve surrounding the rotary component, surrounded by said piston and defining with the piston and with said wall a fluid-receiving annular plenum chamber, said sleeve including a radially outwardly extending flange between an end portion of said wall and an end face of the transmission case;
- and
- means for coupling said flange to said wall, including a plurality of projections borne by said flange and spaced apart from each other in a circumferential direction of said wall, said projections having first portions surrounding said end portion of said wall and second portions recessed into said wall.
