Abstract

PURPOSE: To prevent the abnormal increase in pressure of working oil by constituting the device so that the only appropriate amount of oil which is necessary for heat radiation flows and the surplus oil is extracted through the relief valve by providing the orifice on the working oil inlet side of the oil cooler.
CONSTITUTION: Oil pressurized by the oil hydraulic pressure pump 1 which is driven by the car engine 2 is branched off into the clutch control circuit 5 and the torque converter circuit 7. When the forward or backward clutch is connected by pressurized oil through the oil passage 14 or 15, the pressurized oil becomes unservicable and is returned to the circuit 7. The torque converter circuit 7 is equipped ped with the oil cooler 27 in the back flow of the torque converter 25, the orifice 30, which flows not all working oil from the outlet pressure adjusting valve 26 but only the amount that is necessary for heat radiation to the oil cooler 27, and the relief valve 32, which opens when the pressure of pressurized oil on the upstream side of the orifice 30 exceeds the fixed value, are inserted to prevent the pressure of oil from becoming abnormally high.
