What is the working principle of an electromagnetic valve?

The electromagnetic valve has a closed chamber with through holes at different positions, each connected to a different oil pipe. The middle of the chamber is a piston, and there are two electromagnets on both sides. The magnetic coil on which side is energized will attract the valve body to which side. By controlling the movement of the valve body, different oil discharge holes can be opened or closed. The oil inlet hole is always open, and hydraulic oil will enter different oil discharge pipes. Then, the pressure of the oil will push the piston of the oil cylinder, which in turn drives the piston rod and the piston rod drives the mechanical device. In this way, mechanical motion is controlled by controlling the current flow of the electromagnet.
