Abstract

PURPOSE: To enable to directly feed hydraulic press to the other system without passing through a valve mechanism when a failure is caused in one system, by a method wherein a valve mechanism is bypassed by means of a flow path which is provided to a plunger and is operated by the move of the plunger.
CONSTITUTION: The plunger 10 is provided with a valve 13 which performs proportional control subject to the tension of a spring 20. The floating piston 22 is located in a normal position by the hydraulic press of the other system, pushing the valve 13. When a failure is caused in the other system, the floating piston 22 is moved backward, then, the plunger 10 is also moved rightward by the hydraulic press. Since a tapered part 18 of a plunger 10 is located to an outflow port 16 by the move of the plunger 10, a valve 13 is bypassed and pressure reducing control is no longer conducted. Thus, the braking effect is ensured.
