| description | An impeller for increasing the pressure of a fluid circulating in an annular fluid path, the impeller comprising : a plurality of centrifugal compressor vanes circumferentially interspaced around the axis of the annular fluid path, the plurality of compressor vanes extending from an axially-oriented inlet to a radially- oriented outlet, and each having an inner edge and a free edge, the free edge of the plurality of compressor vanes coinciding with an outer limit of the annular fluid path, and a hub having a solid-of-revolution shape centered around an axis, the hub having an outer hub surface forming an inner limit to the annular fluid path and to which the inner edge of the plurality of centrifugal vanes is secured, the outer hub surface having a portion which leans forward, forming an axial recess therein.
Un rotor pour accroître la pression dun fluide circulant dans une voie à fluide annulaire comprend : plusieurs soupapes de compresseur centrifuge espacées sur la circonférence autour de laxe de la voie annulaire, les soupapes sétendant dune entrée en sens axial à une sortie en sens radial, chacune ayant un bord intérieur et un bord libre, le bord libre des soupapes coïncidant avec la limite extérieure de la voie annulaire, et un moyeu ayant une forme de solide de révolution centrée autour dun axe et une surface de moyeu extérieure formant une limite intérieure de la voie annulaire à laquelle le bord intérieur des soupapes est attaché, la surface extérieure du moyeu ayant une partie inclinée vers lavant pour former une cavité axiale. |
