Regulating system (loaded condition)
Loading
When the net pressure decreases to the loading pressure, solenoid valve (Y1) is energised.
• Control pressure is fed from the oil separator vessel via solenoid valve (Y1) to loading plunger (LP) and
unloading valve (UV).
• Unloading valve (UV) closes the air blow-off opening. Loading plunger (LP) moves downwards and
causes inlet valve (IV) to open fully.
Air delivery is resumed (100%), the compressor runs loaded.
