The working principle of automotive solenoid valve is that electric energy flows through the coil to produce electromagnetic suction force, which attracts the valve core and drives the valve body to produce a response action. The solenoid valve consists of a solenoid coil, an iron core, a valve body, a valve stem and a return spring. When the current passes through the coil, a magnetic field is generated to attract the iron core and drive the valve stem to move, thus changing the opening and closing state of the valve. When the current is cut off, the iron core is reset under the action of the reset spring, and the valve returns to the original state
