Abstract
A reversible sealing mechanism for sealing a bulkhead having a first central aperture defined along a central axis and disposed between first and second compartments includes a cover member having a recess defined therein by a substantially cylindrical sidewall and adapted to cover the first central aperture. A wedge ring having a generally cylindrical body is accommodated by the first and second central apertures and is configured to operatively engage the cover member. A mechanical input is operative to reversibly rotate the wedge ring about the central axis such that a rotation of the wedge ring in a first direction urges the cover member in the axial direction into a sealed position.
