Abstract

Un joint d'étanchéité à haute pression est formé d'un anneau d'étanchéité d'usure (7) dans une gorge annulaire (3) d'un premier élément (1) et d'un anneau de serrage précontraint radialement. L'anneau (7) est appliqué de manière étanche contre le second élément (2) par sa surface périphérique (13) sur toute sa longueur axiale, est souscalibré axialement par rapport à la largeur de la gorge (3) et est mobile entre les deux flancs (4,5) de la gorge (3) pour former une surface d'étanchéité statique.
