What is the function of an automotive electronic valve?

[LeMila]

Here is an introduction to the function of an automotive solenoid valve: 1. Principle: When energized, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, opening the valve; when de-energized, the electromagnetic force disappears, and the spring presses the closing member against the valve seat, closing the valve. 2. Function: The solenoid valve uses the electromagnetic force generated by the current flowing through the coil to attract the valve core (overcoming the spring or self-gravity). It is divided into normally open and normally closed types. It is usually used to cut off the flow of substances such as oil, water, and gas. It works in conjunction with electrical equipment such as pressure and temperature sensors to achieve automatic control. 3. Characteristics: It can operate normally under vacuum, negative pressure, and zero pressure, but the diameter generally does not exceed 25mm.
