Abstract
PURPOSE: To supplement insufficient braking pressure by selecting the cross-sectional areas of a plunger and a piston, and the resilient forces of springs to increase a break point of liquid pressure or to cease the control of proportional pressure reduction when one system is failed.
CONSTITUTION: A plunger 10, a follow piston 11 and an offset piston 12 are incorporated into a cylinder 2 of a valve body 1 provided with a first and a second valve mechanisms 5, 8. The cross-sectional areas A,C.B,D,E,F of the plunger 10, the follow piston 11, an offset piston 11 and a poppet valve 24, and the resilient forces S1, S2 of springs 15, 25 are respectively selected to predetermined values. When a first system is failed, input pressure PM2 of a second system increases, and output pressure PR2 thereof becomes a level having no control of proportional pressure reduction. Further, when the first system is failed, input pressure PM1 increases so that a break point of liquid pressure can be increased.
