Abstract

Un distributeur composé de secteurs (15) d’aubes fixes (5) reliés à l’extérieur à un stator comporte une plate-forme intérieure divisée en une partie extérieure formée de secteurs et associée par des liaisons à glissières radiales à une partie intérieure en forme d’anneau (18) continu sur une circonférence, qui porte une garniture d’étanchéité abradable (17). Des ressorts (27) assurent la position radiale de la couronne (18), et sa concentricité au reste de la machine. Le diamètre de la couronne (18) est déterminé essentiellement par la température des gaz qui passent devant elle. Une meilleure étanchéité peut être obtenue. Figure pour l’abrégé : Figure 2.
