Hydraulic system of motor vehicle, has hydraulic displacement unit that is switched between valve device and pressure cylinder based on pressure set in pressure cylinder

摘要

The system has a hydraulic pressure supply unit (4) to supply hydraulic pressure to a pressure cylinder (5) through a valve device (10). A hydraulic displacement unit (30) is switched between the valve device and the pressure cylinder based on the pressure set in the pressure cylinder. The hydraulic displacement unit is connected parallel to a hydraulic resistor (38,60). A rear side (26) of the hydraulic displacement unit is connected with a low-pass filter (41,42).
