A rotary engine is described including: (1) a rotor located within a housing, the rotor configured with a plurality of rotor vane slots; (2) a vane separating an interior space between the rotor and the housing into at least a trailing chamber and a leading chamber, where the vane slidingly engages a rotor vane slot; (3) a first passage through the vane, the first passage including a first exit port into the rotationally trailing chamber; and (4) a second exit port to the rotationally trailing chamber, where the first exit port and the second exit port connect to any of: (a) the first passage through the vane and (b) the first passage and a second passage through the vane, respectively. Optionally, one or more seals affixed to the vane and/or the rotor valve the first passage, the second passage, a vane wingtip, and/or a conduit through the rotor.

1. A rotary apparatus, comprising: a rotor located within a stator, said rotor and said stator defining an interior space therebetween;a vane slidingly engaged in a rotor vane slot of said rotor, said vane separating said interior space into a rotationally trailing chamber and a rotationally leading
1. A rotary apparatus, comprising: a rotor located within a stator, said rotor and said stator defining an interior space therebetween;a vane slidingly engaged in a rotor vane slot of said rotor, said vane separating said interior space into a rotationally trailing chamber and a rotationally leading chamber;a first passage through said vane, said first passage comprising a first exit port into said rotationally trailing chamber, said first exit port comprising an opening on a rotationally trailing side of said vane; anda second exit port to said rotationally trailing chamber, said second exit port comprising an opening on at least one of: said rotationally trailing side of said vane; anda bottom edge of a radial extension from a top of said vane, wherein said first exit port and said second exit port connect to any of:said first passage; andsaid first passage and a second passage through said vane, respectively. 2. The apparatus of claim 1, further comprising: a conduit, through said rotor, from said trailing chamber to said rotor vane slot, said conduit comprising: an entrance port from said trailing chamber; andan exit port into said rotor vane slot. 3. The apparatus of claim 2, further comprising: a seal affixed to said vane, said seal configured to valve said exit port of said conduit through said rotor. 4. The apparatus of claim 2, further comprising: a wing tip extending, proximate said housing, from said vane into said trailing chamber, said wing tip configured to valve said entrance port of said conduit as a function of rotation of said rotor. 5. The apparatus of claim 2, further comprising: a seal affixed to said rotor, said seal configured to valve, as a function of rotation of said rotor, said first exit port of said first passage through said vane. 6. A method for use of a rotary apparatus, comprising the steps of: providing a rotor located within a stator, said rotor and said stator defining an interior space therebetween;slidingly engaging a vane in a rotor vane slot of said rotor, said vane separating said interior space into a rotationally trailing chamber and a rotationally leading chamber;providing a first passage through said vane;providing a first exit port into said rotationally trailing chamber;providing a second exit port into said rotationally trailing chamber,wherein said first exit port and said second exit port connect to any of: said first passage through said vane; andsaid first passage through said vane and a second passage through said vane, respectively; andpassing a fuel sequentially through at least a radially inward end of said first passage and then through at least one of said first exit port and said second exit port. 7. The method of claim 6, further comprising the step of: providing a conduit through said rotor from said trailing chamber to said rotor vane slot, said conduit comprising: an entrance port from said trailing chamber; andan exit port into said rotor vane slot. 8. The method of claim 7, further comprising the step of: valving said exit port of said conduit through said rotor using a seal affixed to said vane. 9. The method of claim 7, further comprising the step of: providing a wing tip extending, proximate said housing, from said vane into said trailing chamber; andusing said wing tip to valve said entrance port of said conduit as a function of rotation of said rotor. 10. The method of claim 7, further comprising the steps of: providing a seal affixed to said rotor; andvalving with said seal, as a function of rotation of said rotor, said first exit port of said first passage through said vane. 11. A rotary apparatus, comprising: a rotor located within a stator, said rotor and said stator defining an interior space therebetween;a vane slidingly engaged in a rotor vane slot of said rotor, said vane separating said interior space into a rotationally trailing chamber and a rotationally leading chamber;a passage through said vane, said passage comprising a radial axis, said passage splitting into: a first branching vane conduit, wherein at least a portion of said first branching vane conduit comprises a longitudinal axis at least ninety degrees off of said radial axis; anda second branching vane conduit, wherein at least a portion of said second branching vane conduit comprises a lateral axis at least ninety degrees off of said radial axis;a first exit port to said rotationally trailing chamber, said first exit port connected to said first branching vane conduit; anda second exit port to said rotationally trailing chamber, said second exit port connected to said second branching vane conduit. 12. The apparatus of claim 11, further comprising: a conduit, through said rotor, from said trailing chamber to said rotor vane slot, said conduit comprising: an entrance port from said trailing chamber; andan exit port into said rotor vane slot. 13. The apparatus of claim 12, further comprising: a seal affixed to said vane, said seal configured to valve said exit port of said conduit through said rotor. 14. The apparatus of claim 12, further comprising: a wing tip extending, proximate said housing, from said vane into said trailing chamber, said wing tip configured to valve said entrance port of said conduit as a function of rotation of said rotor. 15. The apparatus of claim 12, further comprising: a seal affixed to said rotor, said seal configured to valve, as a function of rotation of said rotor, said first exit port of said first passage through said vane. 16. A rotary apparatus, comprising: a rotor eccentrically positioned within a housing, said rotor and said housing defining an interior space therebetween;a shaft through a radially geometric center of said rotor;a vane slidingly engaged in a rotor vane slot of said rotor, said vane separating said interior space into a rotationally trailing chamber and a rotationally leading chamber; andat least one passage sequentially running from a radially geometric center of said shaft, through said vane, and through an exit port to said rotationally trailing chamber; anda conduit, through said rotor, from said trailing chamber to said rotor vane slot, said conduit comprising: an entrance port from said trailing chamber; andan exit port into said rotor vane slot. 17. The apparatus of claim 16, further comprising: a seal affixed to said vane, said seal configured to valve said exit port of said conduit through said rotor. 18. The apparatus of claim 16, further comprising: a wing tip extending, proximate said housing, from said vane into said trailing chamber, said wing tip configured to valve said entrance port of said conduit as a function of rotation of said rotor. 19.
