Abstract

DIAPHRAGME SOUPLE POUR LA SEPARATION DE PHASES A L'INTERIEUR DE RECIPIENTS DE STOCKAGE DE FLUIDES. IL EST CONSTITUE PAR UNE MEMBRANE CYLINDRIQUE 2 PLACEE A L'INTERIEUR DU RECIPIENT 1. CETTE MEMBRANE PRESENTE UNE EXTREMITE FERMEE SUR ELLE-MEME A JOINT ETANCHE 8 LE LONG D'UNE LIGNE, L'EXTREMITE OPPOSEE 7 ETANT FIXEE AU RECIPIENT A JOINT ETANCHE LE LONG DE SA CIRCONFERENCE. EN OUTRE, CETTE MEMBRANE CYLINDRIQUE EST CONSTITUEE PAR AU MOINS UNE BANDE DE MATIERE SOUPLE 10 ENROULEE EN HELICE. APPLICATION AU STOCKAGE DE FLUIDES DANS DES RECIPIENTS TELS QUE RESERVOIRS POUR VEHICULES AUTOMOBILES DANS DES RECIPIENTS FIXES DESTINES A ETRE POSES SUR UN FOND SOUS-MARIN COMME COLONNES D'APPUI DE PLATES-FORMES DE FORAGE EN MER.SOFT DIAPHRAGM FOR PHASE SEPARATION INSIDE FLUID STORAGE CONTAINERS. IT IS CONSTITUTED BY A CYLINDRICAL MEMBRANE 2 PLACED INSIDE THE CONTAINER 1. THIS MEMBRANE HAS A CLOSED END ON ITSELF WITH A WATERPROOF JOINT 8 ALONG A LINE, THE OPPOSITE END 7 IS ATTACHED TO THE CONTAINER WITH A SEALED SEAL ALONG ITS CIRCUMFERENCE. FURTHERMORE, THIS CYLINDRICAL MEMBRANE IS CONSTITUTED BY AT LEAST ONE BAND OF SOFT MATERIAL WOUND IN A HELIX. APPLICATION TO THE STORAGE OF FLUIDS IN CONTAINERS SUCH AS TANKS FOR MOTOR VEHICLES IN FIXED CONTAINERS INTENDED TO BE LAYED ON AN UNDERWATER BOTTOM AS SUPPORT COLUMNS FOR SEA BORING PLATFORMS.
