Abstract
A stationary annular plenum rotatably mounted upon a hollow shaft receives air from a stationary source of air under pressure. A spring loaded first ring within the plenum conveys the air through apertures therein from the plenum to corresponding apertures in an adjacent second ring, which rings are maintained in alignment with one another and the plenum by a plurality of dowels. An annular channel disposed in a radial face of the second ring interconnects the apertures extending through the ring; the channel mates with a corresponding channel of an adjacent disc fixedly mounted upon the shaft to convey air from the stationary elements to the rotating elements. An air seal between the second ring and the disc is formed by interfacing flat annular radially oriented surfaces on opposed sides of the respective channels. The disc includes a radial passageway interconnecting the channel formed therein with the bore of the hollow shaft to direct air into the bore.
