According to the control signal provided by the ECU, that is, the current signal, a magnetic field is generated in the OCV coil. Under the action of the magnetic field, the iron core moves
against the sliding core in the direction of the strong magnetic field. When the magnetic field strength becomes weak, the spring pushes the sliding core in the opposite direction mobile.
Due to the gap between the spool valve and the sliding sleeve, when the oil inlets of the inlet angle and the ruler angle are closed by the spool valve,
a small amount of oil leaks from the supply back to the oil port
