Abstract:
A Moineau style stator includes a helical cavity component having reinforced helical lobes. The lobes are reinforced with a three-dimensional network of physically bonded aggregate particles. The network of bonded aggregate provides a porous skeletal-like structural reinforcement. Pore volume between the bonded aggregate particles may optionally be partially or substantially filled with an elastomer. An elastomer liner is typically deployed on an inner surface of the helical lobes to promote a rotational interference fit with a rotor.
