PURPOSE:To perform fine adjustment of fluid pressure to a control chamber, by controlling pressing force of a control plunger in a brake fluid pressure controller through the control chamber, providing a check valve between the control chamber and a deceleration sensing valve and providing a relief valve between said chamber and an inlet. CONSTITUTION:A P-valve 12 reduces pressure of fluid from an inlet 5 to guide the fluid to an outlet 6 and receive control force from a spring 15. A control plunger 16, pressing the spring 15, receives fluid pressure in a control chamber 17. The fluid pressure in the control chamber 17 is determined by a deceleration sensing valve 11. A check valve 20 and relief valve 23 are provided in the control chamber 17. Pumping action is performed in the control chamber 17 by these valves to perform air bleed operation, and the necessity for using a bleeder can be eliminated. |
