Research on Hydraulic Response Characteristics of Inlet Valve Used in Hydraulic Braking System

Hydraulic modulator regulates the pressure of four wheels independently to realize the Anti-lock Braking System (ABS) and the Electronic Stability Control (ESC) function. The pressure regulator, also called hydraulic control unit, works by controlling several valves to realize the on-off operation of the liquid paths. This paper focuses on working mechanism and hydraulic response characteristics of inlet valve of hydraulic control unit through simulation analysis.
