LUBRICATION, COOLING AND SEALING
- Oil is forced by air pressure from the oil reservoir through
the oil cooler, thermostatic mixing valve, and oil filter and discharges into the compressor main oil gallery.
A portion of the oil is directed through internal passages to the bearings, gears and shaft oil seal. The
balance of the oil is injected directly into the compression chamber to remove heat of compression, seal
internal clearances and lubricate the rotors.
TURN VALVE
- The turn valve is a rotary helical valve located on the discharge side of the cylinder
toward the inlet end. The valve opens and closes ports in the cylinder which communicates with the inlet
passage. This varies the compressor rotor volume to match the demand for air, thus reducing the part-
load power requirement.
