When energized, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve is opened; when the power is off, the electromagnetic force disappears, the spring presses the closing member against the valve seat, and the valve is closed.

When the solenoid valve is closed, no oil pressure acts on the left end of the shift valve, and the shift valve moves to the left end under the action of the spring force at the right end; when the solenoid valve is opened, the pressure oil of the main oil passage acts on the left end of the shift valve via the solenoid valve The shift valve is moved to the right end against the spring force, thereby generating an oil passage change and realizing the shift.
