Abstract
Un joint d'étanchéité (14) disposé dans une fente (8) entre deux parties de virole (6, 7) de moteur d'aéronef disjointes et soumises à des mouvements aléatoires, est repoussé vers la face d'appui par un piston (15) fermant un logement (17) exposé à une pression de fluide déterminée, quelles que soient les variations de jeux de la fente (8), contrairement à un ressort classique.
