ABSTRACT:
A clutch unit has an oil pump which is powered by the input shaft and an oil pump which is powered by the output shaft. The oil pump powered by the input shaft pumps oil in both a clockwise and counterclockwise rotation of the input shaft. The oil flow is controlled by a unique bi-directional check valve which automatically selects the passage through which oil is being pumped. The oil pump powered by the output shaft provides oil to the friction plates of the clutch only when the clutch is engaged.
