ABSTRACT:
A clutch disengaging apparatus wherein an annular cylinder defines an annular cylinder chamber receiving a reciprocable annular piston with an annular outer clearance surrounding the outer skirt of the piston and an annular inner clearance surrounding the inner skirt of the piston. A membrane overlies the bottom wall of the piston and its marginal portions are clamped between the sections of the cylinder so that the membrane forms an outer corrugation in the outer clearance and an inner corrugation in the inner clearance. A throw-out bearing is radially movably mounted in the piston and is biased against the prongs of the diaphragm spring in a clutch by a coil spring which is surrounded by an inner wall of the cylinder, which surrounds an outer wall of the cylinder, or which is installed in the cylinder chamber between the bottom walls of the piston and the cylinder. The piston is guided against radial movement with reference to the cylinder by a tubular guide member which is connected to or forms an integral part of the inner wall of the cylinder and is tracked by one or more followers of the piston.
