ENGINE OIL PUMP

1 – Partition

2 - Oil supply duct

3 - Driven gear

4. Drive gear

5 - Low pressure chamber

6 - Relief valve

7 - Pressure chamber

8. Duct between high and low pressure

B. CONSTRUCTIONANDWORKING:

The engine oil is drawn in by the sump by means of

the vacuum created by the rot ation of the gears on

the crankshaft.

There is a vacuum from the partition (1) for the gears

as far as the oil sump suction head.

The pressure develops starting from the partition (1)

in all the engine supply ducts (2).

When the pressure exceeds 5 bar, the force exerted

on the restrictor valve (6) overcomes the reaction of

the spring underneath and moves the valve until the

connecting duct (8) between the pressure chamber

(7) and the low pressure chamber (5) opens.
