Ventilation gas is blown to a stator ring (3) to regulate the distance between said ring and the end of the moving blades (5) and reduce leaks in a machine turbine. Communication between successive chambers (18, 19, 20) is enabled by means of fixing hooks (26, 27, 28 et 29) of a strut (10) supporting the ring (3) on the crankcase (2) in order to reduce stress concentrations in said strut (10).

Du gaz de ventilation est soufflé vers un anneau de stator (3) pour régler sa distance du bout d'aubes mobiles (5) et diminuer les fuites dans une turbine de machine. On propose d'opérer des communications entre chambres successives (18, 19, 20) à travers des crochets (26, 27, 28 et 29) de fixation d'une entretoise (10) de support de l'anneau (3) au carter (2), afin de réduire les concentrations de contrainte dans cette entretoise (10).
