1. In combination:

  • a rotatable member having a wall enclosing a chamber, said chamber containing a fluid;

    at least one nozzle on said rotatable member extending through said wall into said chamber with at least one opening proximate each end of said nozzle to permit said fluid to be sprayed outwardly from said rotatable member, said at least one opening proximate the end of said nozzle within said chamber extending in a direction nonperpendicular to the axis of rotation of said rotatable member to avoid clogging of said opening by particles acted upon by centrifugal force upon rotation;

    said rotatable member comprising a hollow shaft exteriorly supporting heat generating means to be coolEd by said fluid;

    said nozzle being an elongated member having a bore disposed perpendicular to the axis of rotation of said shaft and an outer opening directly at the end of said bore for emission of said fluid in directions perpendicular to said axis;

    the inner end of said nozzle being closed facing said axis with a plurality of openings to said bore only from surfaces of said nozzle that run perpendicular to said axis.
