IMPROVEMENT IN HYDRAULIC BRAKING SYSTEMS FOR VEHICLES

摘要

In an hydraulic braking system for vehicles a pedal-operated booster-assisted hydraulic master cylinder assembly (1) is adapted to apply a vehicle brake (2) by the supply of hydraulic fluid under pressure to a brake actuator for operating the brake, and a proportional valve (50) is arranged to provide a quick-fill function for the brake actuator in response to a proportional pilot signal (40) from the master cylinder assembly.
