Oil pump

OIL PUMP

The oil is sucked from the sump through a vacuum created by the gears on the crankshaft rotating. The vacuum starts from the separating panel (2) of the gears unto the oil sump suction device.

The pressure develops from the separating panel (2), in all the engine oil delivery ducts (4). When the pressure exceeds 5 bar, the thrust exercised on the relief valve (5) causes the spring positioned below to react and moves the valve enough to open the connection duct between the pressure chamber (3) and the low pressure chamber (1), limiting the maximum pressure in the circuit.
