ABSTRACT:
A hydraulic pressure regulator in a V-belt type continuously variable transmission for vehicles comprises a torque ratio pressure control valve providing torque ratio pressure corresponding to the reduction ratio between input and output shafts, a regulator valve receiving the torque ratio pressure and providing the line pressure corresponding to the torque ratio pressure, and feedback passages of output hydraulic pressure of the torque ratio pressure control valve acting on the torque ratio pressure passage through an orifice. In the hydraulic pressure regulator, the feedback hydraulic pressure is changed in intake or exhaust state and the torque ratio pressure entered to the regulator valve is varied stepwise corresponding to the throttle opening, and the line pressure is controlled stepwise corresponding to the throttle opening, thereby the line pressure can be approached to the minimum value required by the hydraulic control circuit. Thus loss of the driving force of the engine on account of the oil pump can be reduced and the rate of fuel consumption in the engine be also reduced.
