Abstract

L’invention concerne une partie de turbomachine comprenant un premier secteur de distributeur (4a) et un deuxième secteur de distributeur (4b), et un dispositif de joint d’étanchéité comprenant des languettes (5) s’étendant dans des espaces (19) entre les premier et deuxième secteurs et dans des fentes (11 ;11a,11b) de celles-ci, pour limiter les fuites de fluide à l’endroit desdits espaces. 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.The invention relates to a turbomachine part comprising a first nozzle sector (4a) and a second nozzle sector (4b), and a sealing device comprising tongues (5) extending into spaces (19) between the first and second sectors and in slots (11; 11a, 11b) thereof, to limit fluid leaks at the location of said spaces. The tongues comprise plates (50) provided with axially elongated tabs (51), resting in the slots, to lock the plates (50) therein. Figure to be published with abstract: Figure 6.
