2.2 Main Component Units and their Functions
Oil Cooler/Aftercooler
Oil cooler and After-
cooler are separated
unit, however, the first
cools lubricant while
the second cools com-
pressed air.
Cooling Fan Motor
Totally enclosed 6-pole
motor is used.
Oil Separator
This separates lubri-
cant content from the
compressed air.
Relief Valve
This unlocks and re-
leases compressed air
when the inner pres-
sure of the separator
element abnormally in-
creases.
Oil Separator tank
internal pressure gauge
Oil Level Gauge
Oil Separator Tank
This makes primary
separation of lubricant
content from the com-
pressed air, and its
lower part serves an oil
sump.
Oil Temperature
Control Valve
This retains the oil tem-
perature at the appro-
priate level.
Oil Filter
This filtrates impurities
from lubricant.
Air Intake Filter
This prevents foreign
bodies in the air from
being taken in the com-
pressor.
Starter
Main Motor
Permanent Magnet
Synchronous Motor.
Minimum Pressure
/ Check Valve
This is found at the oil
separator's outlet and
regulate the minimum
pressure as 0.45 MPa
or over. By this action,
the valve prevent lubri-
cant from carryover
due to increased flow
speed at low pressure.
Suction Throttle Valve
This controls capacity
of air intake against
load fluctuation.
