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 (ELECTRA-SAVER ONLY)
- 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.
