A master cylinder for the clutch or brake of a motor vehicle has a housing for a reciprocable piston one end of which receives the spherical head of a reciprocable piston rod. The head is held in a desired position relative to the piston by a one-piece or composite coupling device having a first section exerting a pull or bearing upon the head of the piston rod and a second section which is confined in or surrounds the end of the piston and urges the first section in a direction to hold the piston rod against axial movements relative to the piston. The coupling device and/or the piston are or can be made of a plastic material, and the connection between such parts is or can be established by snap action.

Master cylinder

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.
