Patent 07073477 - Gorski rotary engine > Claims

  • 1. A rotary engine comprising a) a cylindrical housing having a peripheral wall with an internal surface;b) a rotor offset within said housing;c) a plurality of vanes associated with said rotor in a manner such that said vanes rotate with said rotor while being permitted radial sliding movement relative thereto;d) an intake orifice;e) an exhaust orifice; andf) a plurality of grooves in said internal surface of said peripheral wall beginning downstream of said intake orifice, said plurality of grooves extending over a distance generally equal to one quadrant of said peripheral wall;
    • 2. The rotary engine of claim 1 wherein said plurality of vanes are comprised of solid vane members which extend through said rotor simultaneously engaging opposing portions of said peripheral wall.
      • 3. The rotary engine of claim 2 further comprising a plurality of roller bearings which engage lateral portions of each of said vane members facilitating their radial sliding movement.
        • 4. The rotary engine of claim 3 wherein said plurality of rollers bearings comprise at least two pairs of roller bearings engaging each vane member.
    • 5. The rotary engine of claim 1 wherein said plurality of vanes comprise two vanes which extend through said rotor, each said vane having a portion of a central panel of said vane removed to permit clearance relative to another said vane.
    • 6. The rotary engine of claim 1 wherein said rotary housing is made of cast iron.
      • 7. The rotary engine of claim 6 further comprising a ceramic coating on said internal surface of said cast iron rotary housing.
        • 8. The rotary engine of claim 7 further comprising a ceramic coating on at least a major portion of the external surface of said rotor.
    • 9. The rotary engine of claim 1 further comprising an output drive shaft attached to said rotor to allow power takeoff from said rotary engine.
  • 10. A robust rotary engine having operating temperatures exceeding 850° F. comprising a) an uncooled cylindrical cast iron housing having a peripheral wall with an internal surface coated with a ceramic coating;b) a rotor offset within said housing;c) a plurality of vanes associated with said rotor in a manner such that said vanes rotate with said rotor while being permitted radial sliding movement relative thereto, said radial sliding being accomplished solely by contact between end portions of said vanes and said internal surface of said cylindrical housing;d) an intake orifice; ande) an exhaust orifice;
    • 11. The rotary engine of claim 10 further comprising a plurality of grooves in said internal surface of said peripheral wall beginning downstream of said intake orifice, said plurality of grooves extending over a distance generally equal to one quadrant of said peripheral wall;
      • 12. The rotary engine of claim 11 further comprising a plurality of injection ports positioned about a periphery of said rotary housing along a length of said grooves for injection of at least one of substances selected from a group consisting of fuel and water.
        • 13. The rotary engine of claim 12 wherein said fuels are selected from a group consisting of gasoline, diesel fuel, and substitute hybrid hydrocarbons.
  • 14. A rotary engine comprising a) a cylindrical housing having a peripheral wall with an internal surface;b) a rotor offset within said housing;c) a plurality of solid vanes, each of said solid vanes extending entirely through said rotor and having two ends simultaneously engaging opposing portions of said internal surface of said peripheral wall, said solid vanes being associated with said rotor in a manner permitting said vanes to rotate with said rotor while simultaneously being permitted radial sliding movement relative thereto;d) an intake orifice;e) an exhaust orifice; andf) means permitting expanding gases to bypass at least one proximate vane whereby expanding gases bypass at least one proximate vane when an end portion of said proximate vane is in contact with said internal surface, said expanding gases engaging a vane which is not proximate said internal surface which has a greater surface area exposed than a surface area of said proximate vane.
    • 15. The rotary engine of claim 14 further comprising a plurality of roller bearings which engage lateral portions of each of said vanes facilitating their longitudinal sliding movement.
      • 16. The rotary engine of claim 15 wherein said plurality of rollers bearings comprise at least two pairs of roller bearings engaging each vane.
        • 17. The rotary of engine of claim 16 wherein said at least two pair of roller bearings comprise at least six pair of roller bearings, three said pair at each of said first and second ends.
    • 18. The rotary engine of claim 14 wherein said means permitting expanding gases to bypass at least one vane comprises a plurality of grooves in said internal surface of said peripheral wall beginning downstream of said intake orifice, said plurality of grooves extending over a distance generally equal to one quadrant of said peripheral wall.
      • 19. The rotary engine of claim 18 further comprising a plurality of injection ports positioned about a periphery of said rotary housing along a length of said grooves.
