置。 A pressure regulator valve responds to the throttle pressure to adjust the oil from the oil pump to a line pressure proportional to the engine output torque, and a pressure regulator valve responds to the vehicle speed to adjust the throttle pressure at high vehicle speeds. The oil pump is equipped with a pressure modifier valve that acts additionally in the opposite direction to lower the line pressure, and the oil pump passes through the port of the pressure regulator valve, which tends to close as the line pressure increases. The automatic transmission is equipped with a torque converter in the power transmission system that is supplied with oil as hydraulic oil, and the pressure modifier valve is configured to direct throttle pressure to the torque converter at low vehicle speeds. Torque converter hydraulic oil supply device for automatic transmission.
