ークリフトの油圧クラツチ潤滑回路。 A lubrication circuit for the hydraulic clutch of the transmission is created by merging the circuit that passes through the oil cooler from the torque converter and the relief circuit from the cooler relief valve that provides relief when the pressure of oil supplied to the oil cooler exceeds a predetermined value. In a forklift hydraulic clutch lubrication circuit that supplies line pressure from an inching valve to the hydraulic clutch via a transmission select valve, the drain circuit of the inching valve is connected to the inlet side of the cooler relief valve. Hydraulic clutch lubrication circuit for forklifts.
