Pilot valve for controlling balancing unit for balancing pressure in simulator equipped with control system of motor vehicle brake, has feeding unit feeding pressure to valve when pressure in input valve exceeds predetermined threshold

摘要

The valve (90) has two input valves hydraulically connected to two pressure chambers (36, 38) of a master cylinder (28). An outlet valve is hydraulically connected to a balancing unit (82) for balancing pressure in a hydraulic simulator (20). One of the input valves and the outlet valve are provided to be in communication, and the other input valve is isolated when the valve is in a secondary position. A feeding unit feeds the pressure to the valve through the secondary position when the pressure in the former input valve exceeds a predetermined threshold.
