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.
Claims3
In a two stage compressor, of which the first stage is a centripetal stage, and the second one is a centrifugal stage of the disc type, mounted upon a common shaft and together forming a flow path where the fluid to be compressed flows radially inwards the first stage and radially outwards in the second stage, the improvement being that the first centripetal stage is provided with adjustable inlet guide vanes as well as with outlet vanes immediately downstream of the rotor vanes, said inlet, rotor and outlet vanes, respectively, being individually formed with the same profile over the full length of the respective type of vane.
