Oil pressure regulating valve (Ver. 2): Notes

The engine has a volume-flow-regulated oil pump. This volume-flow-controlled oil pump only delivers exactly as much oil as each operating range of the engine requires.

For the volume-flow-controlled oil pump, the oil pressure control valve is integrated. The control via a characteristic map influences the oil pressure in the controllable oil chamber. Two valves are involved in the oil-pressure control:

• Oil pressure regulating valve
• Pressure limiting valve (mechanical) as emergency operation
