Abstract

DISPOSITIF D'ETANCHEITE POUR ASSURER L'ETANCHEITE A UN LIQUIDE, ENTRE UN MILIEU AMBIANT ET L'INTERIEUR D'UNE CAVITE MENAGEE ENTRE UN ELEMENT STATIONNAIRE ET UN ELEMENT TOURNANT. IL COMPREND DEUX ELEMENTS ANNULAIRES D'ETANCHEITE DONT CHACUN PRESENTE UNE SURFACE ANNULAIRE PLANE ET UNE SURFACE LATERALE CYLINDRIQUE. L'UN DES ELEMENTS D'ETANCHEITE EST LIE A L'ELEMENT FIXE ET L'AUTRE A L'ELEMENT TOURNANT; LES DEUX SURFACES PLANES ANNULTAIRES SONT ASSOCIEES ET DES MOYENS DE BUTEE AXIALE SONT PREVUS POUR MAINTENIR ASSOCIEES LESDITES SURFACES ANNULAIRES PLANES, LES DEUX SURFACES LATERALES CYLINDRIQUES DES DEUX ELEMENTS D'ETANCHEITE AYANT LE MEME DIAMETRE ET ETANT SENSIBLEMENT EN COINCIDENCE.
