Abstract

PURPOSE: To improve fuel consumption and drive performance by regulating a line pressure approximately to the least but sufficient level so as to reduce a loss in an oil pump by means of a torque ratio pressure valve, a throttle valve, a regulator valve and a cutback valve.
CONSTITUTION: A hydraulic pressure regulator 60 comrises a regulator valve 61 for regulating hydraulic pressure produced by a hydraulic pressure source 50 to obtain a line pressure which is distributed to various hydraulic components in the hydraulic circuit through a passage 1, a throttle valve 65 for delivering the line pressure in accordance with variations in the open degree of a carburettor throttle, a torque ratio pressure control valve 66 for adjusting the line pressure in response to the displacement of the movable flange of an output pulley so as to deliver a torque ratio pressure, and a cutback valve 6 for receiving the torque ratio pressure and adjusting a throttle pressure so as to deliver a cutback pressure. With using these valves, the line pressure is regulated approximately to the least but sufficient level, thereby to reduce a loss in the engine output power due to an oil pump.
