摘要： A rotary engine for generating mechanical power from energy in a fluid stream includes a positive-displacement air compressor, a combustion chamber and a multiple-stage positive-displacement power extractor or expander, all arranged about a common drive shaft. Eccentrically mounted inner and outer cylindrical members in the expander form a crescent-shaped expansion chamber which is divided by circumferentially spaced rocker-slipper vanes into a plurality of expansion stages. Combustion gases entering the expansion stages are caused to expand upon movement thereof toward the chamber exhaust, and thus to deliver energy to one of the inner or outer members and thence to the drive shaft. A direct connection with the compressor provides high-pressure air flows within the expander for cooling and for sealing the expansion stages against leakage of combustion gases or lubricants, while reducing wear, partly by balancing the pressure forces exerted on the slippers by the combustion gases so as to urge the slippers into light sealing contact with the opposed member. The inner and outer members are arranged either to nutate one to the other or to rotate together at nearly the same speed, yielding significantly reduced relative sliding velocities therebetween to further reduce wear. Similar low-wear conditions are provided in the compressor, where eccentrically mounted double screw vanes, of a general V-shape in cross section, are caused to nutate within correspondingly shaped cavities in the housing so as to displace air at increasing pressure spirally towards a central outlet from suction inlets at each end. The vanes preferably are composed of flexible, nonmetallic material to simplify sealing and to enhance heat-transfer characteristics. Variable lead vanes may be used to develop optimum compression ratios.
