摘要

The stage (10) has a distributor comprising fixed radial blades (14) whose radial external ends are secured to an annular crown (16) that is extended from a part on 360 degree. The crown is connected to an external casing (22) surrounding the distributor by an elastically deformable annular unit. The annular unit includes a flexible annular ring (48) extended on 360 degree around the crown. The ring is secured to upstream end of the crown of the distributor and radially supported on the casing toward outer side at its downstream end.
