Abstract

L'invention concerne une machine à turbine du type axial. Elle comporte un rotor et un stator constitué par un carter et des cloisons avec des aubes distributrices. Les cloisons sont divisées en deux parties assemblées par des bagues qui sont fixées axialement de manière à guider les cloisons dans les directions axiale et radiale tout en permettant leur dilatation thermique. L'invention s'applique notamment à des moteurs à turbines.
