return from th e high—pressure pump — 8. Cylinder for opening outlet lin e — 9. Fuel outlet — 10. Fuel delivery
When the PWM is in regulation mode the coil (1) is energised (between 0—1600mA depending on the pressure required by
the ECM) and the core (2) is moving the shutter (4) towards the closing position in order to limit the fuel flow to the HPP and
thereby reducing the fuel pressure in the rail.
The cylinder (8) in the pressure relief valve will move into a balance position and there it will maintain the pressure in the low
pressure line at 5 bar.
