Abstract
A device for transmitting torque between two rotatable shaft members (2, 3) in a stationary housing (1) contains a number of alternate clutch discs (10, 11) engageable to counteract differential rotational speed between the two shaft members, to which they are connected, a hydraulic clutch piston (12) to engage the clutch discs and a hydraulic pump arrangement (13-22) driven by the speed differential between the two shaft members. An externally controllable pressure-reducing valve (25-27) is provided in the hydraulic connection from the clutch piston to the low pressure side of the pump arrangement, whose high pressure side is connected to the clutch piston.
