Lubrication System Components

The lubrication system of your engine consists of four major components. These components are as follows:

a.      Lube Oil Pump

b.      Pressure Relief Valve

c.       Oil Filter

d.      Oil Cooler

1. Lube Oil Pump: Actually, there are two types of lube oil pumps in the market. These are-

i. Rotary Type

ii. Gear Type

 Rotary type pumps use impellers to such and deliver lube oil from oil sump to all moving parts of the engine. However, gear type pump uses a pair of meshing gears that creates gap in between them. Lube oil is carried out at high pressure though these gaps. 

2. Pressure Relief Valve: You may find this valve in your lubrication system. The main function of this valve is to prevent excessive pressure of lube oil. You can also say it the pressure regulating valve. This type of valves contains spring loaded plunger or ball to control the oil pressure.
3. Oil Filter: The main function of this filter is to clean all impurities contained by the lube oil of your engine as like combustion impurities and products of wear. 
4. Oil Cooler: The oil cooler of your engine removes extra heat from lube oil, which is generated from all moving parts or heat taken from the engine cylinder. Practically, the oil cooler uses some tubes that contain hot oil, and the air passing through tube exteriors removes extra heat from lube oil.
