Abstract:
PCT No. PCT/DE97/02376 Sec. 371 Date May 26, 1998 Sec. 102(e) Date May 26, 1998 PCT Filed Oct. 16, 1997 PCT Pub. No. WO98/17561 PCT Pub. Date Apr. 30, 1998A sealing system for a closing flap in a passage orifice of a facility where, in a coupled position, the closing flap rests in parallel against an identical closing flap on another facility in a sealing plane and cooperates therewith in such a way that the interiors of the two facilities are connected to one another. In a closed position, the individual closing flap has a seal on its circumference for sealing off an associated passage orifice. At least one of the two cooperating closing flaps has, on its circumference, a groove which is delimited on both sides by annular legs. A first leg delimits the groove toward the interior of the respective facility and extends near to the sealing surface of the passage orifice. The second leg is radially shortened relative to the first leg. Located on the seal, in the region radially outside the shortened leg, is an elastic bead which axially overlaps the shortened leg and, when the facilities are in the uncoupled position, at least partially projects beyond the sealing plane. The seal can be subjected to a pressure medium from inside.
