Abstract: Cryogenic liquid for cooling the rotor of a superconducting generator enters the rotor along the inner surface of a centrally-disposed rotating conduit extending into the rotor. From the resulting annulus of liquid coolant surrounding a vapor core, liquid coolant flows via a pair of liquid-delivery ducts to the surface of the pool of coolant bathing the rotor windings. Each delivery duct comprises a radially-extending receiving tube and a radially-extending delivery tube interconnected by an over-flow trap. The outer end of the delivery tube is in flow communication with the vapor in the central core of the rotor winding chamber and the inner end of the receiving tube is in flow communication with both the liquid coolant and the vapor core in the rotating conduit.
