  • Torque converter clutch with a torque reversal release valve assembly
    Patent number: 4427099
    Abstract: A torque converter clutch is released from engagement when the direction of drive torque reverses from an engine drive condition to a vehicle coast condition. Upon torque reversal, a pair of staged or sequentially operated poppet type valves are opened to balance the fluid pressure in the apply and release chambers of the clutch to effectively cause clutch disengagement. The poppet type valves are opened to release the clutch by a cam surface disposed on the clutch vibration damper.
