Hydraulic brake system for motor vehicle, has conduit connecting vacuum chamber and valve for controlling slide portion to cut connection or another slide portion to form connection to neutralize simulator based on vacuum in brake booster

摘要

The system has an actuator (200) with a cylinder (210) forming a pressure chamber connected to a brake simulator (160). A pneumatic control valve (230) is installed in a hydraulic conduit (201) that forms a hydraulic connection between the chamber and a brake fluid tank (170). A pneumatic conduit (232) connects a vacuum chamber of a brake booster (100) and the valve for controlling a slide portion to cut the connection or another slide portion (231b) to form the connection to depressurize the pressure chamber and neutralize the simulator based on vacuum or absence of vacuum in the booster.
