Abstract
In order to permanently ensure the confinement of two closed volumes with respect to the outside atmosphere, while permitting the linking of said volumes, use is made of two gaskets, each having in section an approximately circular and generally hollow part, as well as a part forming a member. One of the gaskets is mounted by its member in a groove formed in a door received in a flange of the volume, whereas the member of the other gasket is fixed in a groove formed in a flange in which is received a door of the other volume. During engagement, the circular parts of the gaskets are in tight contact with one another and on V-shaped inclined surfaces formed within the flange and on the periphery of the door.
Claims7
A disconnectable device for linking two closed volumes without breaking the confinement thereof with respect to the external atmosphere, each of these closed volumes having at least one circular opening with a given axis, defined by a flange and normally sealed by a door, said device incorporating means for the disconnectable fixing of the doors to the flanges, means for the disconnectable fixing of the flanges to one another, means for the disconnectable fixing of the doors to one another and sealing means for permanently ensuring a confinement of said closed volumes with respect to the external atmosphere, wherein the sealing means comprise two annular gaskets, each having in section an approximately circular part and at least one projecting part forming a fixing member, the member of a first of said gaskets being sealingly located in a groove formed in the door of a first of the closed volumes, the approximately circular part of said gasket being in tight contact with two surfaces inclined with respect to the axes of the openings and formed respectively on the flange of the first closed volume and on the door of the second closed volume when all the fixing means are connected, the member of the second gasket being sealingly located in a groove formed in the flange of the second closed volume, the approximately circular part of said second gasket being in tight contact with two other surfaces inclined with respect to the axes of the openings and respectively formed on the door of the second closed volume and on the flange of the first closed volume, as well as with the approximately circular part of the first gasket when all the fixing means are connected.
