Circle ellipse engine

A circle-ellipse engine comprising:

• an identical pair of end plates, assuring exact placement of the vane tip for all rotation angles;
• wherein said end plates have an internal pin track;
• wherein said end plates incorporate provisions for accepting aspirated intake air;
• wherein said end plates incorporate provisions for exhausting combustion product gases;
• and
• wherein said end plates incorporate an internal race to accept either a thrust bearing or a roller bearing on the inside race of each of the identical pair of said end plates;
• a plurality of vanes, each including apex seal slots:
• a plurality of spring-loaded apex seals to close the gap between the vane tip and the inner elliptical cam surface of the housing;
• a rotor, including combustion chambers and face seal cavities;
• a plurality of spring-loaded face seals prevent leakage of the exhaust gas and of unwanted lubrication oil into said combustion chamber;
• a drive shaft including an internal passageway for supplying cooling and lubrication oil;
• inlet ports for aspirating air into said housing;
• exhaust ports for expelling exhaust gas out of said a housing containing passageways;
• and
• dual pin tracks;
• wherein the plurality of said vanes are positioned in relationship to an inner elliptical cam surface of the housing by said dual pin tracks;
• wherein said dual pin tracks integrates said rotor, the plurality of said vanes and said housing to assure a displacement of a tip of the plurality of said vanes in all rotation angles;
• and
• wherein the lubrication oil is delivered to said dual pin tracks via lubrication oil ports attaching to flow restrictors.
