Claims

[Claims for Utility Model Registration] A hydraulic pump; a control hydraulic chamber communicating with the discharge port of the hydraulic pump; when the pressure in the chamber is high, the brake oil passage between the master cylinder and the wheel brakes is communicated; when the pressure is low, the hydraulic a modulator that suppresses the hydraulic pressure of the wheel brakes by blocking the brake oil passage; a dump valve that opens and closes the discharge oil passage connected to the control oil pressure chamber of the modulator; and a dump valve that opens and closes the discharge oil passage connected to the control oil pressure chamber of the modulator; An anti-lock control device comprising a wheel deceleration sensor that opens and closes the valve, a valve case having a valve hole that communicates between the control hydraulic chamber and the discharge oil path, and a valve case that is housed in the valve case to open and close the valve hole, and a valve body connected to a wheel deceleration sensor; the valve case is provided with a valve seat made of an elastic material on which the valve body seats when closing the valve hole; 1. A dump valve for an anti-lock control device, comprising a support portion that supports the valve body when compressed by a predetermined amount.
