Oil Pump: Description and Operation

GF18.10-P-4000MCC Component Description For the Oil Pump








1 Oil pump
2 Timing case cover

Location
The oil pump is located on the side of the engine and is integrated in the timing case cover.

Task
The oil pump generates the required engine oil pressure for lubrication of the engine.







Function
The internal rotor (3) driven by the crankshaft drives the outer rotor (4) via the outer toothing. The volume between the gearwheels increases initially and thus generates a vacuum. The engine oil is suctioned out of the oil pan (6). The volume between the gearwheels and the engine oil reduces at the upper end of the delivery path and the engine oil is pushed back into the oil circuit. As the rpm increases the pressure inside the pump also increases. This is regulated via the pressure limiting valve (5). Excess engine oil is led back into the oil pan.
