Abstract

PURPOSE: To provide the subject valve wherein a locking mechanism is provided at a stiffenig plate, and when one system of two pressure-reducing circuits is in trouble, the mechanism operates to accurately carry out the release of the pressure-reducing operation at the live side.
CONSTITUTION: A guide pin 27 is fitted to a stiffening plate 26, and loosely fitted into a guide hole 28 provided between plungers 23 and 23'. A staged part 29 is provided at the leading end of said pin 27. When one system of pressure-reducing circuits is in trouble, the plunger of this system stands still, and the stiffening plate 26 inclines in response to the movement of the plunger of other system, and the pin 27 also inclines. The staged part 29 is engaged with the shoulder of the guide hole 28 thereby to limit further axial movement of the stiffening plate 26, as a result of which the stroke is limited and the valve seat is not closed, and the liquid pressure from the pressure generating source can be supplied as it is.
