Abstract:
1. A vacuum enclosure for coupling a cryogenic fluid handling hose to a cryogenic fluid holding structure, comprising: an interface collar adapted to be mounted to an end of the cryogenic fluid handling hose; a bellows coupled at a first end to the interface collar and coupled at a second end to a pass-through collar; a slide cuff coupled to the pass-through collar and extending over at least a portion of the bellows and the interface collar, wherein the slide cuff is axially displaceable relative to the interface collar to facilitate movement of the slide cuff between a retracted position and an extended position; and a connecting nut coupled to the pass-through collar and longitudinally separated from the slide cuff by a thrust bushing disposed longitudinally intermediate the connecting nut and the slide cuff, the connecting nut configured to releasably engage a portion of the cryogenic fluid holding structure; wherein in the extended position the pass-through collar and the bellows form a sealed conduit between the cryogenic fluid handling hose and the cryogenic fluid holding structure.
