Abstract
Une léchette (5) de joint d'étanchéité à labyrinthe comprend, se dressant sur une de ses faces latérales (7), un déflecteur (13) qui canalise l'écoulement de gaz tangent à la léchette (5) vers la garniture d'étanchéité (4) en regard, de manière à perturber l'écoulement de fuite (22) à travers le jeu et en diminuer le débit.
