ブレーキ装置の油圧制御装置。[Claims for Utility Model Registration] A master cylinder, a brake device communicating with the master cylinder via an oil passage, and a pressure increase position for supplying pressure oil output from the master cylinder to the brake device, and a pressure increasing position for supplying pressure oil to the brake device. A two-position solenoid valve is provided in the oil passage and has a depressurizing position for discharging the pressurized oil to the reservoir, and this two-position solenoid valve is duty-controlled between the pressure increasing position and the depressurizing position, so that the wheels are an anti-lock control means that increases the proportion of the pressure reducing position when it is determined that the lock is in the lock state, and increases the proportion of the pressure increasing position in other cases; a variable hydraulic valve provided therein, and when the hydraulic pressure between the variable hydraulic valve and the two-position solenoid valve exceeds a set value, the variable hydraulic pressure valve is controlled to suppress a further increase in the hydraulic pressure; A hydraulic control device for an anti-lock brake system for a vehicle, comprising: a control means; and a pump for circulating oil discharged into the reservoir into an oil path between the master cylinder and the variable hydraulic valve. .
