[0002] At present, the solenoid valves for ABS on the market can be roughly divided into two types, namely the boost valve that controls the increase of ABS wheel cylinder pressure and the pressure reducing valve that controls the decrease of ABS wheel cylinder pressure. In addition to the two valves of ABS, there are two other solenoid valves for ESC, namely the isolation valve that controls ESC boost and the suction valve that controls ESC pressure maintenance. These four valves are mainly used to control wheel cylinder pressure, and their performance directly affects the performance of ABS and ESC, and then affects the safety of the vehicle. The performance requirements of solenoid valves mainly include pressure change rate, flow, leakage, response time, directional opening pressure, current pressure difference characteristics, opening current and controllable flow.
