    摘要： A thick walled Moineau-style stator and method of manufacture are disclosed. The outer profile of the stator follows the inner helical profile of the stator. The application of an elastomeric layer to the inner profile of the stator results in a constant thickness for the elastomeric layer and proximity for the walls of the stator. This improves the durability of the motor because of lower heat generation and better heat dissipation. The stator walls also support the elastomeric layer. Further, the thick walls of the preferred stator eliminate the need for additional drill piping or other support provided adjacent the stator. Thus, the cost of additional piping and difficulties placing a stator inside drill pipe or drill string housing are eliminated. Further, the improved strength of thick wall steel when contrasted to a thin wall counterpart allows a higher operating pressure drop for a given stator length, resulting in a higher power output. Moreover, the undulating outer profile of the stator provides a distinctive appearance to the stator piping.

    摘要： A rotary device for an engine includes a stator and a rotor concentric with and rotatable about an axis with respect to the stator. The rotor and the stator cooperate to provide a working chamber. A plurality of vanes are supported for radial movement on one of the stator and the rotor. Fluid is taken into the working chamber through an intake port and exhausted from the working chamber through an exhaust port. A biasing device biases each of the vanes to seal against one of the stator and the rotor. An actuator moves each of the vanes radially against the biasing device to a retracted position to vary a thermodynamic cycle of the rotary device as the rotor rotates with respect to the stator.

    摘要： A method of manufacturing a thick walled Moineau-style stator entails drawing a thick walled tube through rotatable internal and external dies to form a helical outer profile including crests and through on the tube. The tube initially has one end with a diameter smaller than the others, with the smaller diameter end being inserted between the inner and outer dies, where it is seized and drawn through the dies.
