Abstract

Ce distributeur est du type dans lequel les aubes sont montées pour pivoter chacune autour d'un axe de rotation et peuvent être refroidies en fonctionnement. Suivant l'invention, il est caractérisé en ce que ses couronnes intérieure et extérieure sont composées de segments 4, 5, à des joints étanches, chaque aube 2 tourillonnant par des tourillons de pied 6 et de tête 7 dans ces segments, une couronne intérieure de stator ininterrompue 5 étant centrée sur les segments 4 de la couronne intérieure, la fixation radiale et axiale du distributeur 1 ainsi que son verrouillage étant assurés par les segments 5 de la couronne extérieure, les aubes 2 présentant des embases 18, 19 sur lesquelles sont fixés les tourillons 6, 7 qui sont réalisés sous la forme de cylindres creux pour former des passages d'air de refroidissement.
