Abstract

A vehicle clutch having clutch plate and disc members within a sealed clutch housing operative to effect engagement and disengagement of the clutch by operation of a disengaging member. An oil pump structurally associated with the disengaging member provides oil for the clutch through a guide wheel which is axially movable together with the disengaging member. In the engaged position, a deflector directs an oil stream from the guide wheel through openings to the clutch plate and disc members, while in the disengaged position a pump wheel is provided with pump impeller blades to deflect the oil stream from the guide wheel away from the clutch plate and disc members.
