Operation
Cross-section through the rotors of a typical screw compressor with a male rotor having 5 lobes and a female rotor having 6. For five rotations of the female rotor, the male rotor makes six rotations.

Rotary-screw compressors use two meshing helical screws, known as rotors, to compress the gas. In a dry-running rotary-screw compressor, timing gears ensure that the male and female rotors maintain precise alignment. In an oil-flooded rotary-screw compressor, lubricating oil bridges the space between the rotors, both providing a hydraulic seal and transferring mechanical energy between the driving and driven rotor. Gas enters at the suction side and moves through the threads as the screws rotate. The meshing rotors force the gas through the compressor, and the gas exits at the end of the screws.

The effectiveness of this mechanism is dependent on precisely fitting clearances between the helical rotors and between the rotors and the chamber for sealing of the compression cavities. However, some leakage is inevitable, and high rotational speeds must be used to minimize the ratio of leakage flow rate over effective flow rate.
BOTH A SCREW TYPE AND A LOBE TYPE compress air by meshing the screws/lobes so that there is a difference in the amount of space between the screws/lobes where the air comes in and where the air goes out. The greater that difference, the greater the P/R. The difference between the types is in the way the air is moved through them.
