Abstract

PURPOSE: To reduce the loss of an output power of an engine by an oil pump to improve the fuel cost and the power performance of the engine by minimizing the line pressure with a torque ratio pressure control valve, a throttle valve, a regulator valve, and the like.
CONSTITUTION: A V-belt type infinitely variable speed change gear includes a pair of variable diameter pulleys mounted on each of input and output shafts thereof. The effective diameter of each pulley is controlled by a respective hydraulic servo system. The torque ratio between the input and output shafts is infinitely varied by controlling the hydraulic pressure of supply oil to the hydraulic servo system. A hydraulic pressure regulator for supply of the line pressure includes a torque ratio pressure control valve 66 which provides a torque ratio pressure in accordance with the torque ratio between the input and output shafts, a throttle valve 65, and a regulator valve 61. The hydraulic pressure regulator additionally includes a cut-back valve 67 which receives the torque ratio pressure and provides to the throttle valve 65 a cut-back pressure corresponding to the torque ratio pressure when the torque ratio is higher than a preset level.
