  • Torque converter slipping clutch and control
    Patent number: 4643283
    Abstract: A torque converter and slipping clutch assembly has an adjustable apply orifice which establishes the torque split between the torque converter and the clutch. The orifice controls fluid communication between clutch engagement and disengagement chambers to establish the effective clutch apply pressure. A viscous damper is connected to the clutch and torque converter in parallel with the orifice to prevent rapid adjustment of the orifice during transient torque impulses.

  • Torque reversal control valve for a torque converter clutch
    Patent number: 4360090
    Abstract: A torque converter clutch has a normally closed valve member disposed on the clutch pressure plate. During normal forward (engine to transmission) torque transmission, the valve remains closed. Upon torque reversal (transmission to engine), the vibration damper associated with the clutch engages and opens the valve member so that a reduction in clutch apply pressure occurs resulting in clutch disengagement.
