Abstract
PURPOSE: To obtain stable operation even when a means which applies a force corresponding to load is faulty by providing a spring means to force a plunger which opens and closes valves corresponding to input liquid pressure, against the input liquid pressure, independently of a means which applies the force corresponds.
CONSTITUTION: When braking pressurized liquid is supplied to an inlet hold 2 by a master cylinder 5, it is guided to an outlet hole 3 through the channel 12 of a plunger 11 and a spherical valve 13 and is supplied to the rear wheel cylinder 7. In this case, depending upon the difference in the pressure reception area of the small diameter area 11A and intermediate diameter area 11B for the plunger 11, a downward force is obtained due to the input liquid pressure. When this force overcomes that of a spring 23, the plunger 11 falls down and the spherical valve 13 closes, thereby stopping the liquid pressure rise on the side of the outlet hole 3. This pressure reduction operation start pressure is adjusted by raising a stem 18 through a load detection tension spring 27. In this case, the stem 18 is constituted so that it can elastically be forced upward by a compression spring 21.
