Abstract

L'invention porte sur un appareil rotatif à pales fixe ou mobile en rotation. Ledit appareil qui comporte une enveloppe extérieure (11) à travers laquelle un fluide est contraint de passer, se caractérise par une série de pales (12) fixée à l'enveloppe (11), s'étendant vers l'intérieur, munies d'éléments de pas indépendant, et n'étant soutenues que par leur point de fixation sur l'enveloppe. Tout corps solide entraîné dans l'écoulement du fluide peut ainsi traverser sensiblement librement et sans entraves l'appareil sans être retenu par les vannes (12). Les pales (12) peuvent par ailleurs être séparées axialement.
