Abstract

La présente invention concerne une machine rotative. La machine rotative comprend une section turbine dotée d'un boîtier et un anneau accouplé à l'intérieur du boîtier. L'anneau présente une rainure. La machine rotative comprend également une buse accouplée à l'anneau. La buse comprend une première extrémité, une seconde extrémité et une surface portante s'étendant entre les première et seconde extrémités le long d'un axe longitudinal. La première extrémité comprend un premier crochet et un second crochet. Le premier crochet présente une première surface radialement externe, et le second crochet présente une seconde surface radialement externe. L'anneau et la première extrémité de la buse coopèrent pour former un élément anti-rotation qui s'étend à partir d'au moins l'une des surfaces radialement externes le long de l'axe et entre les crochets.
