Abstract
PURPOSE: To prevent heat infiltration into the cryogenic liquid with a simple construction by means of a stepped part or a tapered section provided on the inner surface of a rotary liquid feed tube.
CONSTITUTION: As a cryogenic refrigerant 6 flows into a rotary liquid feed tube 2 from a fixed liquid feed tube 1 as indicated by the arrow, the liquid produces a centrifugal force with the rotation of the tube 2 so that the flow thereof shifts to the larger diameter portion along the inner surface of the lquid feed tube 2 with an aid of a stepped part 8. Therefore, in the rotary clearance 5, a thrust develops in the direction of the dotted arrow due to the flow of the liquid moved outward in the radial direction by the centrifugal force, and controls a circulating current between the gaseous phase part and the lqiudi phase part caused by a gas flow moving inward in the raidal direction depending on the difference in the density of gas in the clearance 5. This can reduce heat filtration into the cryogenic liquid due to this circulating current and helps prevent the heat from filtration into the liquid without particular consideration given to the flexural rigidity and the dimensional accuracy of the rotary liquid feed tube.
