COMPRESSOR OIL SYSTEM (FIGURE 5–1) cools
the compressor, lubricates moving parts and seals in-
ternal clearances in the compression chamber.
The oil inlet line is connected at the bottom of the oil res-
ervoir. Air pressure in the oil reservoir forces oil through
the oil cooler, thermostatic mixing valve, oil filter and
into the compressor main oil gallery.
The oil passes through internal passages for lubrica-
tion, cooling and sealing. The air–oil mixture is then
discharged to the oil reservoir where a large part of
the entrained oil drops out of the air stream; the air
then passes through the final oil separator where most
of the remaining oil is removed. The separated oil is re-
turned to the compressor and the air passes to the final
discharge line.
