Abstract:
1. A hingeless door system for a pressure vessel having a wall that partitions a pressurizable internal space from an external environment comprised of: a. a contour in the wall on the internal side of the vessel wall that forms a retaining surface capable of conformingly receiving an exterior engaging surface of a door; b. a doorway opening that goes through the retaining surface and wall to allow for passage between the internal space and the external environment; c. a pair of spaced-apart, oppositely opposed tracks mounted to the pressure vessel in tangential proximity to the doorway opening, where each of said tracks is comprised of: d. a door delimited by an outer edge that has an exterior engaging surface that conforms to the retaining surface and has at least one member with the capabilities of running along the running surfaces and moving radially on the outward extension that is movably mounted between the running surfaces on the opposing tracks; and e. a seal having a mounting selected from the group consisting of a mounting on the retaining surface that circumscribes the doorway opening and a mounting on the exterior engaging surface of the door delimited by the outer edge, so as to be capable of forming an airtight engagement with an exterior engaging surface of a door.
