ABSTRACT:
Oil shut-off in a wet clutch is performed by the sliding movement of an actuator collar during engagement with pressure plate release levers. An end lip portion of the actuator collar slides over radial openings in a coaxial oil feed tube to terminate oil flow after the clutch plates have been disengaged. Complete oil shut-off substantially reduces viscous drag between the clutch plates during disengagement. Oil flow is restored prior to complete engagement of the clutch plates by return movement of the actuator collar exposing the openings in the coaxial feed tube to the interior oil feed channel in the actuator collar.
