Claims

[Scope of utility model registration request]

Shut valves 23 and 24 are installed in the oil passages 35 and 36 leading from the pressure chambers 11 and 12 of the master cylinder 1 to the left and right brakes of the driving wheels, respectively, and the booster of the hydraulic booster 2 for the master cylinder is provided. inlet valves 29 and 30 each provided in a pressurized oil passage 39 leading from the chamber 2a to the shirt valve downstream side of the oil passage;
Outred valves 32 and 33 are provided in the pressure reducing oil passages 40 that communicate with reservoir No. 16 from the downstream side of the shirt valve of the oil passages 3"5 and 36, respectively, and a hydraulic source that sends pressure oil to the booster chamber. Bypass oil 43 communicates 18.19 with the inlet valve upstream side of the pressurized oil passage, and allows pressurized oil to flow from the booster chamber to the inlet valve when the oil pressure in the booster chamber is equal to or higher than a predetermined pressure value. However, when the oil pressure is below the predetermined pressure value, the pressure sensing type allows pressure oil from the oil pressure source to flow through the bypass oil path to the inlet valve, and prevents pressure oil from flowing to the booster chamber. When the valve means 46, 47 and one of the drive wheels are locked, the corresponding shirt valve is closed, and the corresponding inlet valve and outlet valve /l, /
Hydraulic braking system equipped with an electronically controlled anti-skid device, which controls the opening and closing of the inlet valve, and when one of the drive wheels is idling, closes the corresponding shut valve and opens the corresponding inlet valve. Device.
