<p>PROBLEM TO BE SOLVED: To provide a traction control system fluid pressure supply valve whose structure is simplified and compactified. SOLUTION: A traction control system fluid pressure supply valve is provided with a body 91, a master cylinder connection flow path 92 and a hydraulic pump suction side connection flow path 93, which are formed in the body 91 vertically to each other, an internal flow paths 94, 95 connecting the master cylinder connection flow path 92 and the hydraulic pump suction side connection flow path 93 together, a valve operating member 102 provided with a valve seat 101 opening/closing the internal flow paths 94, 95, a holding spring 106 holding the valve operating member 102, a rod member 104 provided with a ball valve 103 connecting/disconnecting the valve seat 101, and a fixed screw member 105 integrated with the rod member 104. In this way, the valve operating member 102 is driven vertically by means of a brake fluid pressure of the master cylinder and the holding spring 106 so as to open/close a path connecting the master cylinder and the hydraulic pump suction side together, so that a sufficient flow rate can be secured while system structure can be compactified and simplified, and consequently, possibility of an action error or a failure is eliminated and repair and replacement can be carried out easily in case of a failure.</p> |
