Abstract

Distributeur haute pression pour turbomachine et turbomachine comportant un tel distributeur haute pression Un aspect de l’invention concerne un distributeur haute pression pour turbomachine comportant une couronne de pales (30) fixes montées entre une plateforme annulaire interne (10i) et une plateforme annulaire externe (10e), coaxiales, chaque pale (30) comprenant : une paroi intrados (31), une paroi extrados (32), une face interne (34) et une face externe (33), au moins une cavité (35) abritant une chemise d’étanchéité (20) dont une extrémité interne fermée forme une paroi de fond et dont une extrémité externe ouverte débouche dans la plateforme externe (10e), la chemise d’étanchéité (20) étant au moins partiellement déformable et fixée, d’une part à la face externe (33) de la pale et, d’autre part, à la paroi extrados (32) de ladite pale de sorte à assurer un espacement (40) constant entre la chemise d’étanchéité et la paroi extrados de la pale.
