Abstract
A hydraulic booster with an antiskid device, comprising a hydraulic booster type pedal responsive device arranged to introduce from an accumulated pressure source, hydraulic pressure the level of which is determined depending on a pedalling force applied to a brake pedal, a master cylinder type control hydraulic pressure generating device which generates control hydraulic pressure according to the hydraulic action of the introduced hydraulic pressure, and a slave cylinder device arranged to generate braking hydraulic pressure by a power piston which moves by receiving the control hydraulic pressure at one end. The slave cylinder device includes an antiskid fluid chamber arranged to exert hydraulic pressure on the power piston in the direction of returning the power piston, and an antiskid control solenoid operated valve device which is disposed in a transmission line for transmitting the introduced hydraulic pressure of the pedal responsive device and is arranged to supply and discharge a pressure fluid to and from the antiskid fluid chamber on the basis of an antiskid signal input.
