Abstract
An assembly for closure of an opening into a vessel, has a valve chamber, a valve biased toward a closed position in which the valve closes the first opening, and a retainer that retains the valve in an open position. A flow of cryogen from a first opening through the valve chamber to a second opening acts to displace the retainer and allow the valve to close.
