Abstract

Architecture pour joint d’étanchéité de turbomachine L’invention concerne un joint d’étanchéité configuré pour assurer un jeu prédéfini (j) entre ledit joint d’étanchéité et une surface externe (500), et comprenant une pluralité de secteurs de joints répartis circonférentiellement autour de l’axe A, chaque secteur de joint d’étanchéité comprenant un secteur d’anneau interne (13) relié à un secteur d’anneau externe (11) par un organe de rappel (12), le joint d’étanchéité étant caractérisé en ce que la surface radialement interne (Sint) de chaque secteur d’anneau interne comprend au moins un motif (31, 32) creusés à partir de la surface radialement interne des secteurs d’anneau interne,le secteur d’anneau interne comprenant en outre au moins un canal (501) reliant une première ouverture (502) qui débouche sur la face amont du secteur d’anneau interne et une deuxième ouverture (503) qui débouche dans un des motifs creusés à partir de la surface radialement interne des secteurs d’anneau interne. Figure pour l’abrégé : Fig. 1.
