ABSTRACT:
In order to raise the degree of compression without unduly increasing the dimensions a compressor having at least two stages includes a first centripetal stage and a last centrifugal stage mounted upon the same shaft. The diameter at the centripetal stage inlet does not exceed the diameter at the outlet of the centrifugal stage and the air flows radially inwards in the first stage, and radially outwards in the last stage.
