On the other hand, by controlling the movement of the valve body to open or close different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter the different oil drain pipes, and then push the piston of the oil cylinder through the oil pressure, and the piston will It drives the piston rod, and the piston rod drives the mechanical device.

There is a closed cavity in the solenoid valve, with through holes at different positions. Each hole is connected to a different oil pipe. There is a piston in the middle of the cavity, and two electromagnets on both sides.

In this way, the mechanical movement is controlled by controlling the current on and off of the electromagnet.
