Patent ID: 7931135

Claim:
A torque transmitting assembly comprising: a housing that defines a cavity; an actuator slidably disposed within the cavity of the housing, wherein the actuator includes a first surface that cooperates with the housing to define a first space, a second surface that cooperates with the housing to define a second space wherein the first space is hydraulically isolated from the second space, and a third surface that cooperates with the housing to define a third space, wherein the third space is located on a side of the actuator opposite the first and second spaces, and wherein a fluid is located within the third space; a torque transmitting element interconnected with the housing that is selectively engageable by the actuator; and a ball valve connected to the actuator for selectively communicating the fluid located in the third space between the third space and the first space, and wherein the torque transmitting element is engaged by the actuator when a pressurized fluid enters the second space and contacts the second surface of the actuator to move the actuator towards the torque transmitting element, and wherein the fluid within the third space communicates through the ball valve into the first space as the actuator moves.
