    摘要: A generally cylindrical quick disconnect female cryogenic coupler, interconnected with a cryogenic fluid transfer apparatus, includes a coupler body with a first cavity housing a laterally severed tubular bushing, an adaptor having one end attached to the coupler body and another end to the apparatus, a normally closed-biased valve between the coupler body and the adaptor, a coupling sleeve, attached to the coupler body having, a frusto-conical inlet portion, and a vent fitting having one end connected with a coupling sleeve radial aperture and another end in operative connection with a cryogenic fluid storage vessel, associated with the noted apparatus, to permit the inlet purging by using the vessel's own gaseous phase as a purging medium during liquid fluid transfer operation. The severed bushing inhibits ice formation, at an inlet/male nipple interface during the noted transfer. A method for purging moisture at the noted interface is also set forth.
