    • A hydraulic booster for a master cylinder in which an inlet valve is interposed between an output pressure chamber at the back of the booster piston and an input pressure chamber connected to a pressure source. Advance of the valve piston opens the inlet valve. An outlet valve between the output chamber and an outlet chamber connected to an oil tank closes at advance of the valve piston relative to the booster piston. The booster chamber is exposed to a rear of a master cylinder operation piston. The valve piston oil feed passage connects input pressure chamber with booster chamber at opening of the outlet valve. The reaction chamber at the front surface of the booster piston is reduced in volume with the advancing movement and is connected to an accumulator making it possible to smooth initial operation of the master cylinder and reduce booster system size.
    • 一种用于主缸的液压助力器,其中入口阀插入在增压器活塞后面的输出压力室和连接到压力源的输入压力室之间。 阀门活塞的前进打开入口阀。 在输出室和连接到油箱的出口室之间的出口阀在阀活塞相对于增压器活塞的前面关闭。 增压室暴露在主缸操作活塞的后部。 阀门活塞供油通道在输出阀开口处将输入压力室与增压室相连。 增压活塞前表面的反应室随着前进运动而减小体积,并连接到蓄能器,使得可以平稳主缸的初始运转并减小增压系统尺寸。
