Title: Hydraulic rotary clutch

Abstract: A hydraulically operated rotary clutch includes a housing, a triangular rotor, an input gear, an eccentric shaft, a main shaft, a shifting piston, and a mechanism to operate the shifting piston. The rotor orbits in an inner elliptical opening of the housing and forms fluid chambers which are filled with a hydraulic fluid. The hydraulic fluid circulates through fluid passages which extend between all fluid chambers when the shifting piston is positioned to allow such fluid circulation, thereby resulting in a disengagement of a drive and driven member. When the shifting piston is driven to restrict the fluid circulation, the driving force is gradually applied to the driven member. A full-scale power flow is reached when the shifting piston is positioned to completely cut off the fluid circulation between the fluid chambers and when the force exerted by the drive member is transmitted through the fluid onto the driven member.
