Abstract
Herein described is a system for injecting and extracting gas for a fluid rotating machine of the type comprising at least one stator case, one first stage which receives the gas flowing into the machine, one final stage, downstream of which the gas is discharged from the machine, and one or more intermediate stages arranged between the first stage and the final stage. Each stage is made up of a single centrifugal rotor and a fixed ducting, associated to such centrifugal rotor and made on the single stator case. The system comprises at least one first worm screw for extracting gas from the machine and at least one second worm screw for injecting gas into the machine. Both worm screws for extracting gas and for injecting gas are operatively connected to at least one stage of the machine.
