- The casing accommodates a central rotor with vanes that move eccentrically.
- The rotation of the rotor leads to the outward movement of the vanes, creating a seal.
- Through the rotation of the vanes, fluid or gas is drawn into a sealed chamber.
- As a result, the volume of the sealed chamber reduces, compressing the trapped fluid / gas.
- The outlet port enables the expulsion of the compressed fluid / gas.
- The continuous rotation of the rotor sustains the process of suction, compression, and discharge.
