Pedal linkage hydraulic brake booster

摘要

A conventional hydraulic braking system using a master cylinder and a force booster means between the brake pedal and master piston. The force booster means comprises a liquid cylinder and control valve means for selectively communicating the cylinder with a hydraulic pressure source or drain, depending on the application or non-application of manual force to the brake pedal. The control valve is designed to regulate the cylinder movement in accordance with pedal movement while increasing the force applied to the master piston.
