Beschreibung
Zusammenfassung:	The invention relates to a sealing device for rotating and/or sliding seals of pipework for fluids, in particular for high pressure gas, having at least one sealing barrier having at least one annular sealing gasket 1 with concavity bathed by the pressurised fluid. This device comprises at least one second annular sealing gasket 2, coaxial with the first gasket 1 and close to the latter, situated on the side of the fluid which bathes its convex side, the respective concavities, mutually facing one another, of the two gaskets and the space between defining a cavity 3 filled with a non gaseous fluid, which is preferably incompressible. The invention applies especially to pipework for offshore oil industry installations. L'INVENTION CONCERNE UN DISPOSITIF D'ETANCHEITE POUR JOINTS TOURNANTS ETOU GLISSANTS DE TUYAUTERIES DE FLUIDES, EN PARTICULIER DE GAZ A HAUTE PRESSION, A AU MOINS UNE BARRIERE D'ETANCHEITE A AU MOINS UNE GARNITURE DE JOINT D'ETANCHEITE ANNULAIRE 1 A CONCAVITE BAIGNEE PAR LE FLUIDE SOUS PRESSION.CE DISPOSITIF COMPREND AU MOINS UNE DEUXIEME GARNITURE 2 DE JOINT D'ETANCHEITE ANNULAIRE, COAXIALE A LA PREMIERE GARNITURE 1 ET VOISINE DE CELLE-CI, SITUEE DU COTE DU FLUIDE QUI BAIGNE SON COTE CONVEXE, LES CONCAVITES RESPECTIVES, MUTUELLEMENT EN REGARD, DES DEUX GARNITURES ET L'ESPACE INTERCALAIRE DEFINISSANT UNE CAVITE 3 REMPLIE D'UN FLUIDE NON GAZEUX, DE PREFERENCE INCOMPRESSIBLE.L'INVENTION EST APPLICABLE NOTAMMENT A DES TUYAUTERIES D'INSTALLATIONS PETROLIERES EN MER.
