Abstract

L’invention concerne une partie de turbomachine comprenant une première partie sectorisée (4a) et une deuxième partie sectorisée (4b), et un dispositif de joint d’étanchéité comprenant des languettes (5) s’étendant dans des espaces (19) entre les premier et deuxième secteurs de distributeur et dans des fentes (11,11a,11b) de celles-ci, pour sceller lesdits espaces à l’encontre de fuite de fluide. Les languettes comprennent des plaques (50) pourvues de pattes (51) allongées axialement, en appui dans les fentes, pour y bloquer les plaques (50). Figure à publier avec l’abrégé : Figure 6 [Fig. 6]
