A cryogenic liquid coolant transfer device enhances flow of a liquified gas in the inboard direction by the incorporation of a threaded insert in the rotating inlet pipe of a superconducting rotor. The threads of the device also facilitate the reverse flow of liquid helium back into a stationary supply tube during fault conditions. The objective of the insert, during both normal and abnormal conditions, is to inhibit the flow of liquid coolant into the clearance gap that exists between rotating and stationary parts of the liquified gas transfer system.
