The compression process:

1. Discontinuous flow 
2. Induce a fixed volume of gas into a chamber for compression
3. The size of this pocket is then reduced mechanically, compressing the gas. 
4. At the end of the compression cycle pocket opens, discharging the high-pressure gas.
5. There is never an open gas passage from delivery to suction
6. Air is drawn into the center of a rotating impeller with radial blades 
7. Thrown out towards the periphery of the impeller by centrifugal forces
8. Before the air is led to the center of the next impeller it passes a diffuser and a volute
9. The kinetic energy is converted to pressure.
