[2] RELIEF VALVE
The relief valve prevents the damage of the
lubricating system due to high oil pressure. This relief
valve is a ball type direct acting relief valve, and is best
suited for low pressures.
When oil pressure exceeds the upper limit, the ball (2)
is pushed back by the oil pressure and the oil escapes.

[3] OIL FILTER CARTRIDGE
Impurities in engine oil can cause to wear and seize
components as well as impairing the physical and
chemical properties of the oil itself. Impurities contained
in force-fed engine oil are absorbed on the filter paper for
removal as they pass through the filter element (1).
When the filter element is clogged and the oil
pressure in inlet line builds up by 98 kPa (1.0 kgf/cm
2
, 14
psi) more than the outlet line, the bypass valve (2) opens
and the oil flows from inlet to outlet bypassing the filter
element.
