Title:
AUTOMATIC CONTROLLER FOR TRANSMISSION WORKING PRESSURE
Document Type and Number:
Japanese Patent JPS5846259
Kind Code:
A
Abstract:
A fluid pressure regulator valve for use in an automatic power transmission control system for an automotive vehicle having a throttle controlled engine and a transmission throttle valve system connected to the engine throttle, a control pressure booster forming a part of the regulator valve for increasing the regulated line pressure in the control system during operation of the transmission in selected operating modes, a hydraulic connection between the transmission throttle valve and the regulator valve for increasing the regulated line pressure upon an increase in engine torque and means for changing the operating pressure level upon a failure of the mechanical connection between the engine throttle and the transmission throttle valve so that the regulator valve operates at a higher level thereby maintaining adequate pressure on the friction elements of the transmission mechanism.
