Abstract

The cylinder of a cylinder and piston unit in the friction clutch engaging/disengaging apparatus of a power train for use in a motor vehicle is assembled of two separately produced coaxial tubular walls. The outer wall is made of a plastic material and is of one piece with an extension serving to supply pressurized hydraulic fluid from a pump or another source to the plenum chamber for the reciprocable annular piston between the two walls. The inner wall is made of sheet metal and one of its end portions is separably coupled to one end portion of the outer wall by snap action. Such one end portion of the outer wall is separably secured to a support, usually the transmission case in the power train of the motor vehicle.
