Demand-driven oil pump with suction stage (V8)


A newly developed vane-type oil pump with demand-driven quantity regulation and two map-controlled pressure stages is used in the new 6- and 8-cylinder V engines from Mercedes Benz.

.

This control concept allows the engine lubricating and cooling points to be supplied independently of engine load and engine speed absolutely and with a significantly lower drive power particularly in thepart-load range than would be possible with a non.controlled pump. The pump is easy to turn.

The following are easy to recognise:

  • Control piston
  • Cold-start protection valve
  • Valve for motor oil pump
  • Rotor with vane
  • Adjusting ring
  • Toothed wheel for oil pump
