Abstract

L'invention concerne une languette (5) d'un dispositif de joint d'étanchéité d'une partie de turbomachine à gaz pour aéronef. La languette est disposée dans des fentes respectives de parties sectorisées adjacentes de distributeur de la turbomachine. Cette languette présente deux extrémités renflées (51 a,51 b) réunies par une partie intermédiaire (51c) plus fine qui chacune présentent entre elles une liaison (53a,53b), laquelle, par arc-boutement de la languette, peut se déformer vers une position à plat, lorsqu'une surpression est appliquée d'un côté de la languette, sur sa partie intermédiaire.
