Abstract
Joint d'étanchéité monté entre un élément rotatif 1 et un élement fixe 2 pour isoler un espace 4 contenant un milieu sous pression d'un espace externe 5, tel que l'atmosphère. Le joint comporte une bague d'étanchéité 7 montée sur l'un des éléments 2 et une bague d'appui montée sur l'autre élément 1 munies de surfaces de glissement étanches annulaires coopérantes 14, 16. Un espace intermédiaire 19 alimenté en fluide d'étanchéité, l'un des éléments 1 et les surfaces de glissement et la bague d'étanchéité comporte un piston 23 soumis, sur une face, à la pression du fluide d'étanchéité et sur l'autre, à la pression atmosphérique pour accroître la force d'application des surfaces de glissement de sorte que ces surfaces sont toujours soumises à une force de fermeture plus grande que la force d'ouverture qui leur est appliquée, quelles que soient les pressions relatives du milieu sous pression et du fluide d'étanchéité.
