Abstract
A rotary machine has a rotor and a surrounding stator. The rotor has an outer surface with an upstream larger-radius first section, a downstream smaller-radius second section, and an intervening third section which has an area facing in a direction other than perpendicular or parallel to the axis of the rotor. In one example, the area includes a first convex area and a second concave area. The machine also has a first brush seal with bristles whose free ends are positioned near the second section, and the machine may also include a second brush seal with bristles whose free ends are positioned near the first section and with a front plate having a ledge projecting away from its corresponding bristles.
