Zusammenfassung:A coolant supply and discharge device for a superconductive rotor including a gaseous coolant withdrawing tube for withdrawing a gaseous coolant located at an end portion of fixed casing enclosing an end portion of the rotor and supporting a coolant feed tube. The withdrawing tube is constituted to withdraw a predetermined amount of gaseous coolant produced in a clearance between the coolant feed tube and a coolant inlet tube located within a rotor shaft to a coolant sump located outside, to avoid introduction of heat into the feed tube from outside.
