Claims

[Scope of utility model registration request]

The fluid chambers of each of the regulator valve, the bypass valve, and the pressure reducing valve are communicated with the brake hydraulic passage connecting the master cylinder and the wheel cylinder in the brake system of the vehicle, and the fluid chambers of the other of the regulator valve and the bypass valve are communicated with each other. The liquid chamber is communicated with the hydraulic passage on the discharge side of the pump,
Furthermore, in order to adjust the hydraulic pressure applied to the wheel cylinder by changing the volume of one of the liquid chambers in the pressure reducing valve, the other liquid chamber of the pressure reducing valve is switched to hydraulic passages on the discharge side and suction side of the pump, respectively. In the anti-lock device, the anti-lock device is controlled by a control mechanism that communicates with a switching device that enables the locking of the cylinder and the switching device compares vehicle speed and wheel speed to detect a locked state of the wheels. The control valve consists of one control valve consisting of a plunger that rotates and slides at a predetermined angle within the cylinder via a rotary actuator disposed outside the cylinder, and the cylinder has a hydraulic passage on the discharge side of the pump. A pressure oil inlet hole communicating with the suction side hydraulic passage and a pressure oil outlet hole communicating with the suction side hydraulic passage are provided, respectively, and an adjusting pressure oil hole communicating with the hydraulic passage communicating with the other liquid chamber of the pressure reducing valve is provided, The plunger is capable of closing one of the adjusting pressure oil holes of the cylinder and communicating with the other of the pressure oil inlet hole and the pressure oil outlet hole and adjusting the passage opening area by the operation of the rotation actuating device. An anti-lock device characterized in that a communication path is formed.
