  • Apparatus for cooling a clutch assembly with a hydraulic fluid
    Patent number: 4905812
    Abstract: A fluid conduit delivers hydraulic cooling fluid to a mechanism including a clutch assembly which releasably joins two members rotatably mounted on a shaft. A linearly positionable clutch actuator controls operation of the clutch assembly. To avoid flooding of the clutch area with cooling fluid, a mechanism is provided for metering fluid flow delivered to the clutch area as a function of clutch operation. The mechanism includes a sleeve coaxially mounted on the shaft for metering the fluid flow exhausted from the fluid conduit in response to movement of the clutch actuator.
