Title (EN) COVER FOR A CYLINDER-SHAPED PRESSURE CONTAINER
(FR) COUVERCLE POUR ENCEINTE SOUS PRESSION EN FORME DE CYLINDRE
Abstract: front page image
(EN)Cover for a cylinder-shaped pressure container such as a vacuum impregnation container or an autoclave which at the mouth edge has members for holding a tight fitting closure member against the mouth edge which members contrary to previously known and complicated members can be manufactured by means of generally known working processes and machine tools. The mouth edge of the container (1) and the closure member (3) both have a radially outwards directed annular flange (2, 4) which flanges have cooperating contact faces (5) and each a sloping surface, whereby the width of the two flange members (2, 4) is increasing towards the outer edge. The cover further comprises a retaining ring (6) which is placed close to the flange members (2, 4) and which is ended up by two free ends (8). The retaining ring (6) has a slot (7) which is open towards the centre and corresponding to the cross section of the flange members (2, 4), and the circumference of the retaining ring (6) is similar to the outer circumference of the flanges (2, 4) so that the free ends of the ring (6) can be pulled towards each other, when the flange members (2, 4) are assumed in the slot (7) of the ring (6). The free ends (8) of the retaining ring (6) can be connected to driving means (9) of a hydraulic type for the closing of the retaining ring (6) around the flange members (2, 4).
(FR)Un couvercle pour enceinte sous pression en forme de cylindre tel qu"une enceinte sous vide ou un autoclave qui possede sur le bord de son ouverture des elements pour tenir un organe de fermeture etanche contre le bord de l"ouverture, ces elements, contrairement aux elements deja connus et compliques, peuvent etre fabriques par des procedes et des machines outils generalement connus. Le bord de l"ouverture du conteneur (1) et l"organe de fermeture (3) possedent une bride annulaire s"etendant radialement vers l"exterieur (2, 4), ces brides ayant des faces de contact en cooperation (5) et chacune une surface d"inclinaison, la largeur des deux brides (2, 4) augmentant vers le bord exterieur. Le couvercle comprend en outre une bague de retenue (6) qui est placee a proximite des brides (2, 4) et qui se terminent par deux extremites libres (8). La bague de retenue (6) possede une fente (7) qui est ouverte vers le centre et correspond a la section des brides (2, 4), et la circonference de la bague de retenue (6) est identique a la circonference exterieure des brides (2, 4) de sorte que les extremites libres de la bague (6) peuvent etre tirees l"une vers l"autre, lorsque les brides (2, 4) se trouvent dans la fente (7) de la bague (6). Les extremites libres (8) de la bague de retenue (6) peuvent etre connectees a des moyens d"entrainement (9) du type hydraulique pour la fermeture de la bague de retenue (6) autour des brides (2, 4).
