Embodiment Construction
[0031] As shown in FIGS. 1-3, the conventional Moineau motor 20 comprises a helically lobed rotor 22 disposed within a stator, the stator comprising a metal tube 24 having a circular, cylindrical interior wall 26 and a circular, cylindrical exterior wall 28, the interior wall having a molded elastomer liner 30 formed with helical lobes cooperable with the rotor to provide moving fluid chambers as the rotor rotates. As seen in all three of FIGS. 1-3, the thickness of the elastomer liner varies because of the presence of the lobes.
[0032] A Moineau Motor 32 in accordance with the invention, illustrated in FIGS. 4-6, comprises a helically lobed rotor 34 disposed within a stator comprising a tube 36 and a flexible liner 40. The tube 36 is composed of steel or a similar structural material. The tube has an interior wall 38 having helical lobes formed by electrochemical machining, and a circular, cylindrical exterior. Using a suitable mold or core (not shown), the molded liner 40, of rubb...
