Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe oil pump is used to pump oil from the oil sump to the oil galleries at a certain pressure. It is located in the crankcase and is driven by the camshaft.
There are four types of oil pumps used in the engine
1. Gear type oil pump: In this type two gear are fixed in the pump housing. The gears have little clearance with the pump housing. When the gears rotate a vacuum is created in the casing. Oil is sucked through the inlet and pumped to the oil gallery through the outlet.
2. Rotor type oil pump:
The rotor type oil pump consists of an inner driving rotor, and an outer drive rotor which rotates freely in the pump housing and runs eccentrically in relation to the inner rotor.
The oil is sucked into the pump in the side where the volume between the rotor teeth increases and is pumped out on the side where the volume decreases.
3.Vane type oil pump
In the vane type pump the rotor runs eccentrically in the pump housing. Spring- loaded vanes (2) slide against the pump housing walls. Suction is created by the vanes when the rotor rotates. Oil is sucked through the inlet duct and discharged through the discharge duct.
4. Plunger type oil pump: In this type of plunger moves up and down in the cylinder. It is operated by a special eccentric cam. This pump has two non-return ball valves. These valves are spring-loaded balls. One of these is on the suction side. During the upward stroke the oil is sucked through the valve. During the downward stroke the non-return valve closes. The other non-return valve which is on the delivery side opens and permits the oil to flow out from the pump. This type of plunger pump is used in medium and high-pressure lubricating systems.
