Servo-supported hydraulic system for motor vehicle, has pump surge and switching valve mechanism arranged in hydraulic line such that effect of actuating force on master cylinder is additionally reinforced on slave cylinder based on demand

摘要

The system has a master cylinder (1) and a slave cylinder (2), which are connected with each other by a hydraulic line (4). A pump (5) and a servo valve (18) are arranged in the line such that effect of an actuating force applied on the master cylinder is reinforced on the slave cylinder. An additional pump surge (12) with an input and an output, and a switching valve (40) i.e. 3/2 valve, are arranged in the line such that the effect of the actuating force is additionally reinforced on the slave cylinder based on a demand i.e. pedal speed.
