Abstract
A rotary engine having a rotor housing with a bisected, offset elliptical interior wall and a rotor member disposed therein. Four rotor vanes reciprocate radially from within said rotor wherein the opposing vanes perform the same function simultaneously as they pass through the cycle. The rotor vanes are forced out of the rotor by a pressurized oxygen/fuel mixture entering behind the vanes through the ports of the ported side plate. The rotation of the rotor urges the vanes back into the rotor due to the narrowing elliptical walls of the housing thereby forcing the oxygen/fuel mixture through the transfer ports and one-way check valve and into the combustion chamber where it is compressed and ignited.
Claims14
A single cycle elliptical rotary engine comprising:
- a) a housing assembly comprising:
- i) a rotor housing having a substantially hollow bisected, offset elliptical interior;
- ii) an end plate having a plurality of threaded bolt holes, a pair of ignition timing ports having marks of degree and a centrally disposed bearing boss;
- and
- iii) a ported end plate having a pair of opposing ignition timing ports, a pair of opposing exhaust ports, a pair of opposing fuel/oxygen intake ports and a centrally disposed power shaft throughbore leading to a bearing bore of a greater circumference;
- and
- b) a rotor assembly including a substantially cylindrical rotor having a power shaft extending from a central portion thereof;
- c) a plurality of vane guides radiating within said rotor from said power shaft every 90 degrees therefrom;
- d) at least one transfer port communicating perpendicularly between each said vane guide and the exterior sidewall of said rotor;
- and
- e) a vane disposed within each said vane guide with each said vane being of a length and width substantially similar to that of said vane guide and having a depth substantially shorter than that of said vane guide.
