Cutaway Model Demand-driven oil pump without suction stage (V6)

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 the part-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
