Rotary air compressors are positive displacement compressors.
The most common rotary air compressor is the single stage helical or spiral lobe oil flooded screw air compressor.
These compressors consist of two rotors within a casing where the rotors compress the air internally.
There are no valves.
These units are basically oil cooled (with air cooled or water cooled oil coolers) where the oil seals the internal clearances.
