PROBLEM TO BE SOLVED: To compose the system which doesn't have the feeling of disorder in the operating time compared with a normal brake system with no hydraulic control device, by making it possible to store a specific amount of brake fluid inside the device, as well as composing the hydraulic control device to allow to reduce the output hydraulic pressure according to the control current, in an electric automobile necessary to contorl the brake fluid output in order to recover the kinetic energy of the vehicle. SOLUTION: This device is provided with a solenoid valve in which the output is changed according to the current value; an accumulater which is composed in a hydraulic contorl device and can store the input fluid at a specific amount; a pressure control seal abutted to the end of the solenoid output shaft; a check valve in order to prevent that the pressure of the output fluid is made higher than the input hydraulic pressure; and a pressure accumulation control valve 8, a packing 7, and the like, which is operated to store a part of the input fluid to the accumulator, in the operating time of the solenoid valve. |
