Pressure Controlled Clutch Peak Torque Limiter

Abstract

A clutch peak torque limiter for regulating the flow rate of fluid between a clutch master cylinder and slave cylinder in a vehicle transmission, the valve having a non-return valve for allowing free flow of fluid from the clutch master cylinder to the clutch slave cylinder, a return orifice for allowing return flow of fluid from the slave cylinder to the master cylinder, and a pressure controlled valve in parallel with the non-return valve and return orifice for allowing flow of fluid between the slave cylinder and the master cylinder, the valve opening when the pressure on either side of the pressure controlled valve exceeds a predetermined level.
