Supply unit for fuel injection system, with output connection of pressure limiting valve arranged so that fluid can flow direct to induction connection of pump when valve is open

摘要

The supply unit includes a pre-supply pump (8) taking fluid through an induction channel (6) from a tank, with a pressure limiting valve (16) for the feed channel (10). The output connection of the pressure limiting valve is arranged so that fluid can flow directly to the induction connection of the pre-supply pump when the valve is open.
