ABSTRACT:
A constant supply of liquid metal for current collectors in a disk-type acyclic machine is provided by passageways through each stator disk extending from the region adjacent a radially-outer collector to the region adjacent a radially-inner collector. Dynamic pumping of the liquid metal in the region adjacent the outer current collectors is provided by the rotational motion of the rotor disks and by Lorentz expulsion forces acting upon the liquid metal. The openings to said passageways in the region of the outer current collectors are configured to catch a portion of the liquid metal moving with the radially-outer edge of the rotor disks and thereby apply the dynamic pressure of this portion of the liquid metal to move the liquid metal radially-inwardly. Return flow is accommodated by flow paths in the stator separate from those provided for inward flow.
