Document Type and Number:
Japanese Patent JP2638658
Kind Code:
B2
Abstract:
PURPOSE:To supply a refrigerant enough to cool a superconductive field coil to a very low temperature by sloping a wall of a refrigerant supply tube in the direction of an outer diameter of a rotary shaft from the end side of the rotary shaft toward a rotor. CONSTITUTION:A refrigerant supply tube 16 should be in the shape of a taper with its gauge getting larger from the end of a rotary shaft 10a toward a rotor 1. Liquid helium LH, which is sent from a rotor bayonet 13a of a helium transfer coupling, receives a component of a centrifugal force in the taper-shaped refrigerant supply tube 16, gaining a higher flow speed in the shaft direction. Thus a liquid transport capacity of the apparatus is muliplied. Consequently, liquid helium LH can be supplied to a refrigerant storing chamber 5 in the quantities enough to cool the superconductive coil 4 to a very low temperature.
