Abstract
The inventive stator includes a helical cavity component made from a material chosen to reinforce an elastomer liner deployed thereon. The contouring of the elastomer liner is asymmetrical, such that the elastomer liner is relatively thick on the loaded side of a lobe as compared to its thickness on the unloaded side of the lobe.
