ABSTRACT:
A self-acting gap seal for a gap existing between individual modules of a composite, annular pressure vessel comprising a flat, thin-walled seal element on the inside of the pressure vessel to bridge the gap plus the circumferential region adjacent the gap. Internal pressure urges the seal element against the inner wall of the vessel to close and seal the gap to prevent exit of the pressure medium in the vessel.
