Abstract

L'invention concerne un tronçon (10) d'un distributeur de turbine haute pression d'une turbomachine comportant une pluralité de pales (16) creuses agencées en couronne entre deux plateformes (12, 14) annulaires coaxiales, dans lequel chaque pale (16) comporte au moins une cavité (18) abritant une chemise (28) percée d'une pluralité de trous (30) débouchant en direction d'une face interne (34) de ladite cavité (18), caractérisé en ce que la chemise (28) comporte une pluralité d'ergots (36) faisant saillie en direction de ladite face interne (34) de la cavité (18) dont l'extrémité libre de chaque ergot (36) est en contact avec la face interne (34) de la cavité (18), pour maintenir la chemise (28) à distance de la face interne (34) de la cavité (18).
