Abstract

L'INVENTION CONCERNE LES MEMBRANES ELASTIQUES, NOTAMMENT POUR VANNES, CLAPETS, POMPES ET COMPRESSEURS. LA MEMBRANE 10 SELON L'INVENTION COMPORTE UNE BORDURE PROFILEE 12 PERMETTANT LE MONTAGE DE LA MEMBRANE, NOTAMMENT PAR SERRAGE ENTRE DEUX PARTIES D'UN BOITIER POUVANT ETRE TRAVERSE PAR UN FLUIDE ET COMPORTANT DES MOYENS D'ACTIONNEMENT POUR DEFORMER LA MEMBRANE. LA PARTIE DE LA MEMBRANE CONTIGUE A LA BORDURE 12 PRESENTE UNE FACE CONCAVE EN REGARD DU PLAN D'APPUI 12A DE LA BORDURE 12. L'EPAISSEUR DE LA MEMBRANE AUGMENTE REGULIEREMENT, EN ALLANT DE LA BORDURE DE FIXATION 12 JUSQU'AU MILIEU M DE LA MEMBRANE. DANS TOUTES SES POSITIONS PREVUES AU COURS DE SON MOUVEMENT DE DEFORMATION, LA MEMBRANE 10 PRESENTE DANS SA PARTIE COMPRISE ENTRE SA BORDURE DE FIXATION 12 ET SON MILIEU M, UNE VOUTE ANNULAIRE R UNIQUE ET CONTINUE, CONSTAMMENT DISPOSEE DU MEME COTE DU PLAN D'APPUI 12A DE SA BORDURE 12. L'INVENTION PERMET DE CONSTITUER DES MEMBRANES DONT LE RENDEMENT ET L'ENDURANCE SONT NETTEMENT AMELIORES.THE INVENTION CONCERNS ELASTIC MEMBRANES, IN PARTICULAR FOR VALVES, VALVES, PUMPS AND COMPRESSORS. THE MEMBRANE 10 ACCORDING TO THE INVENTION INCLUDES A PROFILED EDGE 12 ALLOWING THE MEMBRANE TO BE MOUNTED, IN PARTICULAR BY TIGHTENING BETWEEN TWO PARTS OF A HOUSING THAT CAN BE THROUGH A FLUID AND INCLUDING ACTUATION MEANS TO DEFORM THE MEMBRANE. THE PART OF THE MEMBRANE CONTIGUATING TO THE EDGE 12 SHOWS A CONCAVE FACE WITH REGARD TO THE SUPPORT PLANE 12A OF THE EDGE 12. THE THICKNESS OF THE MEMBRANE INCREASES REGULARLY, GOING FROM THE FIXING EDGE 12 TO THE MIDDLE M OF THE MEMBRANE. IN ALL ITS POSITIONS PROVIDED FOR DURING ITS DEFORMATION MOVEMENT, MEMBRANE 10 PRESENTED IN ITS PART BETWEEN ITS FIXING EDGE 12 AND ITS MIDDLE M, A SINGLE AND CONTINUOUS ANNULAR VOUCH, CONSTANTLY PROVIDED ON THE SAME SIDE OF THE SUPPORT PLAN 12A OF ITS EDGE 12. THE INVENTION ALLOWS MEMBRANES TO BE CONSTITUTED WHOSE PERFORMANCE AND ENDURANCE ARE SIGNIFICANTLY IMPROVED.
