ABSTRACT:
A coolant replenishing system for cooling the superconducting field winding of a machine, illustratively a turbo-generator. The machine is provided with a rotating antechamber in which is disposed a coolant in liquid and gaseous phases. Liquid coolant is delivered to the antechamber from a supply tank by a coolant supply line. The discharge opening of the coolant supply line in the antechamber is oriented away from the axis of rotation of the machine, and disposed at a predetermined radius with respect to the axis so that the input pressure of the coolant at the opening of the coolant feed line is in equilibrium with the pressure of the liquid coolant in the rotating antechamber.
