Pressure regulator and 5 bar pressure relief valve at max. fuel delivery
1. Coil — 2. Core — 3. Pre—loading spring — 4. Shutter — 5. High—pressure pump supply — 6. Fuel inlet (from the filter) — 7. Fuel
return from the high—pressure pump — 8. Cylinder for opening outlet line — 9. Fuel outlet — 10. Fuel delivery
When the coil (1) of the regulator is not energised, the core (2) is in the rest position due to the pre—loading spring (3). The
shutter (4) is in the position of maximum delivery and the HPP will provide the rail with max. pressure.
The clearance between the internal parts in the high pressure pump permits fuel leakage, which is used to lubricate the pump.
This excess fuel is sent towards the pressure relief valve.
The cylinder (8) in the pressure relief valve will then move into a balanced position and there it will maintain the pressure in the
low pressure line at 5 bar.
