Abstract

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.
