Abstract
A clutch system includes a clutch plate and a reservoir coupled with the clutch plate. The reservoir is configured to receive bailed excess fluid from the clutch upon rotation of the clutch plate. The clutch system also includes a hydraulic control valve fluidly coupled with the clutch plate and the reservoir. A first fluid flow path is defined between the reservoir and the clutch plate. Moreover, the hydraulic control valve includes an orifice fluidly coupled with the reservoir and a lube valve configured to move between a closed position and an open position. Additionally, a cavity is defined in the hydraulic control valve. Finally, the movement of the lube valve between the open position and the closed position is controlled using the fluid from the reservoir which flows though the orifice and into the cavity.
