ABSTRACT:
A fluid operated friction torque transmitting device has an apply piston disposed in a housing. An apply chamber having a predetermined area is formed on one side of the piston, and an opposing or compensating chamber of lesser area is formed on the other side of the piston. A torque transmitting shaft and an inner hub portion of the housing cooperate to form a rotary valve member which is operable to connect the apply chamber to high fluid pressure and the opposing chamber to low fluid pressure, when torque is transmitted from the input side of the transmitter to the output side of the transmitter; and to connect both the apply chamber and the opposing chamber to high fluid pressure when torque is being transmitted from the output side of the transmitter to the input side of the transmitter.
