ABSTRACT:
A multiple disk clutch has a clutch disk stack which is pressed together by a spring arrangement and released by a fluid pressure operated piston which is movable against the force of the spring arrangement. To provide a low cost clutch with fewer parts, the clutch disk stack is placed in an essentially sealed chamber which can be pressurized by a pressure source. One side of the chamber is closed by the piston. The chamber therefore serves both as the clutch disk stack chamber and the piston pressure chamber. If the pressure in the chamber increase, the piston moves against the spring and releases the plates. If the pressure in the chamber decreases, the clutch plates are pressed back together by the spring.
