PURPOSE:To make constant an accumulated pressure irrespectively of the quantity of a fluid and make constant pressure-recovering speed, by using a Belleville spring in an accumulator for accumulating a discharged brake fluid by pressurizing by a pump. CONSTITUTION:A master cylinder 1 is connected to brake cylinders 9a, 9b through a check valve 6 and a solenoid valve 7, a brake fluid discharged from the brake cylinders by the valve 7 is once accumulated in a reservoir 13, is pressurized by the pump 17, and is accumulated in the accumulator 19. The accumulator 19 is comprised of a main body 20, 21, a piston 23 and Belleville springs 26 which are so used that the fluid pressure becomes constant irrespectively of the quantity of the hydraulic fluid accumulated in an accumulating chamber 27. Accordingly, since the accumulated pressure is constant, the pressure-recovering speed becomes constant and can be controlled smoothly. |
