るブレーキ液圧制御装置。[Scope of Claim for Utility Model Registration] Air pressure generated when the brake pedal 1 is depressed is converted into brake fluid pressure by the air master cylinder 3, and this brake fluid pressure is sent to the fluid pressure chamber of the brake fluid pressure adjustment device V. At the same time, the port of the solenoid valve is switched by the control signal output from the control unit U, and the air pressure introduced into the pneumatic chamber of the brake fluid pressure regulator V is regulated by switching this port, and this regulation is performed. The compressed air pressure acts on the pressure receiving piston part 6c, so that the power piston 6 can slide in the large diameter cylinder part 5b of the housing 5 in an airtight manner. The internal volume of a back pressure chamber provided on the opposite side and open to the atmosphere increases or decreases, and the brake fluid pressure in the hydraulic pressure chamber controlled by the sliding movement of the power piston 6 is supplied to the wheel cylinder of the wheel. This brake fluid pressure control device has a peripheral flange 6d projecting from the side surface of the pressure receiving piston part 6c on the back pressure chamber side, which fits inside the large diameter cylinder part 5b and slides in an airtight manner. 6d is in contact with the inner wall surface of the large-diameter cylinder portion 5b and the space formed between the pressure-receiving piston portion 6c and the space is secured as a back pressure chamber when the internal volume is at a minimum. Pressure control device.
