Abstract

L'invention concerne un système de joint (1) destiné à étancher un premier composant (2) par rapport à un deuxième composant (3), comprenant une première structure de centrage de joint (4) fermée dans la direction périphérique. Cette structure sert à centrer un joint (5) par rapport au deuxième composant (3) dans une direction présentant au moins une composante de direction radiale. Le système de joint (1) comporte également une deuxième structure de centrage de joint (6) interrompue dans la direction périphérique. Celle-ci sert également à centrer le joint (5) par rapport au deuxième composant (3) dans une direction présentant au moins une composante de direction radiale.
