のコントロールバルブ。This control valve is installed in a hydraulic circuit between a master cylinder and a wheel cylinder that receives hydraulic pressure generated by the master cylinder and operates a service brake, and controls the hydraulic pressure, and one end communicates with the master cylinder. A first oil port is provided at the other end with a second oil port that communicates with the wheel cylinder, and the inside of this cylinder is partitioned into two chambers that communicate with the first oil port and the second oil port, respectively. a valve seat that allows pressure oil to flow between the surface and the inner wall of the cylinder, is provided with a communication hole that communicates the two chambers, and further has a valve seat formed around the communication hole on the surface on the first oil port side; The ball body is biased toward the valve seat by a spring compressed in the cylinder chamber on the first oil port side, and the ball body is connected to the service brake operating lever, and when the lever is not operated, the ball body is attached with a spring. a ball operating member that presses the ball body against the force to separate it from the valve seat, and releases the pressure when the lever is operated to seat the ball body against the valve seat; and a second oil port side surface of the valve seat. Above, a control valve for a hydraulic brake system for a vehicle is comprised of an annular cup made of an elastic material and arranged such that the male knob opening faces the second oil port and the peripheral wall contacts the inner wall of the cylinder.
