Abstract

Organe de compression centrifuge La présente invention concerne un organe de compression centrifuge (1) comprenant un disque (2) et un ensemble de pales (5, 6) en saillie d’une surface du disque (2), l’ensemble de pales (5, 6) étant agencé en une alternance de pales principales (5) et de pales secondaires (6) disposées autour de l’orifice (4), chacune des pales (5, 6) s’étendant selon une dimension principale curviligne entre un bord d’attaque (53, 61) et un bord de fuite (54, 62) disposé au niveau d’une périphérie (22) du disque (2), caractérisé en ce que le bord de fuite (62) d’au moins une pale secondaire (6) est plus proche du bord de fuite (54) d’une première pale principale adjacente (51) que du bord de fuite (54) d’une deuxième pale principale adjacente (52).
