AND LUBRICATION
SYSTEM, FUNCTIONAL
DESCRIPTION
Refer to Figure 2-4. The compressor cooling and
lubrication system is designed to provide adequate
lubrication as well as maintain the proper operating
temperature of the compressor. In addition to the
cooler and fan, the system consists of a main filter
and thermal valve.

Fluid is used in the system as a coolant and a
lubricant. The fluid is housed in the receiver tank.
Upon start up, the fluid temperature is cool, and
routing to the cooler is not required. The fluid first
enters the thermal valve and then flows on to the
compressor unit, bypassing the cooler. As the
compressor continues to operate, the temperature of
the fluid rises and the thermal valve element begins
to shift. This forces a portion of the fluid to the fluid
cooler. The cooler is a radiator-type that works in
conjunction with a separate motor-driven fan. The
fan blows air through the cooler removing the heat of
compression from the fluid. From the cooler, the fluid
