摘要： A cryogenic device incorporates a liquid storage vessel from near the bottom of which a transfer passage leads to a closed cryogenic chamber having an exhaust passage closable by a liquid level sensitive device in the closed chamber. A heat sink is in heat-exchanging relation with the transfer passage. A by-pass pipe in which a shut-off valve is intercalated connects the upper part of the liquid storage vessel to the transfer passage.
