Claims

[Scope of Claim for Utility Model Registration] A hydraulic pressure control valve that forms two brake fluid passages for a front system and a rear system, which includes a valve housing having stepped holes of a large diameter and a small diameter inside, and a valve housing that slides in the valve housing. A first liquid chamber of the front system formed between the stepped portion of the stepped hole and the corresponding stepped peripheral surface of the intermediate portion of the piston, and the small diameter portion of the stepped hole. A second liquid chamber is formed between the circumferential surface of the upper part of the piston and communicates with the rear system outlet; a third liquid chamber communicating with the liquid path; and a third liquid chamber formed to penetrate in the axial direction of the piston, and the second
a liquid passage that communicates the liquid chamber with the third liquid chamber; a valve mechanism that opens and closes the rear liquid passage at the upper end of the piston; and a spring member that biases the piston in the opening direction of the valve mechanism. A two-system brake fluid pressure control valve, wherein the pressure receiving area of the lower end of the piston is smaller than the effective pressure receiving area of the valve mechanism.
