A rotary engine is described including: (1) a rotor eccentrically located within a housing, the rotor configured with a plurality of rotor vane slots; (2) a first vane of a set of vanes separating an interior space between the rotor and the housing into at least a trailing chamber and a leading chamber, where the first vane slidingly engages a rotor vane slot; (3) a first conduit within the rotor configured to communicate a first flow between the trailing chamber and the rotor vane slot; and (4) a second conduit within the rotor configured to communicate a second flow between the trailing chamber and the first conduit. Optionally, a vane seal is affixed to the first vane or the rotor, where the vane seal is configured to valve the first conduit or a vane conduit, respectively.

1. A rotary engine apparatus, comprising: a rotor eccentrically located within a housing, said rotor and said housing defining an interior space therebetween, said rotor configured with a plurality of rotor vane slots;a set of vanes spanning a distance from said set of rotor vane slots to said housing, said set of vanes separating said interior space into a plurality of chambers, said plurality of chambers comprising at least a trailing chamber and a leading chamber separated by a first vane of said set of vanes, said first vane slidingly engaged within a first rotor vane slot of said set of rotor vane slots;a first conduit within said rotor configured to communicate a first fuel flow between said trailing chamber and said first rotor vane slot, said first conduit comprising a first cross-sectional area;a second conduit within said rotor configured to communicate a second fuel flow between said trailing chamber and said first conduit, said second conduit comprising a second cross-sectional area, said first cross-sectional area larger than said second cross-sectional area; anda flow booster configured to use flow through said second conduit to enhance flow through said first conduit. 2. The apparatus of claim 1, further comprising: a lower trailing vane seal affixed to said first vane, said lower trailing vane seal configured to valve said first conduit with movement of said first vane. 3. The apparatus of claim 2, said rotor configured to rotate relative to said housing, wherein rotation of said rotor levers said first vane resulting in movement of said first vane, said movement of said first vane valving said first conduit through movement of said lower trailing vane seal. 4. The apparatus of claim 1, further comprising: a flow conduit configured to sequentially communicate flow from said first conduit, through said first rotor vane slot, and through said first vane into said trailing chamber. 5. The apparatus of claim 4, further comprising: a trailing upper vane seal configured to valve said flow conduit upon movement of said first vane. 6. The apparatus of claim 4, wherein said flow conduit exits said vane through at least one of: a trailing vane side port of said first vane; anda trailing vane wing port of a trailing vane wing of said first vane. 7. The apparatus of claim 6, said trailing vane wing configured to valve, as a function of rotation of said rotor, at least one of: said first conduit; andsaid second conduit. 8. A method for use of a rotary engine, comprising the steps of: rotating a rotor, said rotor eccentrically located within a housing, said rotor and said housing defining an interior space therebetween, said rotor configured with a plurality of rotor vane slots;separating into a plurality of chambers said interior space using a set of vanes running from said set of rotor vane slots to said housing, said plurality of chambers comprising at least a trailing chamber and a leading chamber separated by a first vane of said set of vanes, said first vane slidingly engaged within a first rotor vane slot of said set of rotor vane slots;communicating a first flow between said trailing chamber and said first rotor vane slot using a first conduit within said rotor, said first conduit comprising a first cross-sectional area;communicating a second flow between said trailing chamber and said first conduit using a second conduit within said rotor, said second conduit comprising a second cross-sectional area, said first cross-sectional area larger than said second cross-sectional area; andusing a flow booster to enhance flow through said first conduit, said flow booster using flow through said second conduit. 9. The method of claim 8, further comprising the step of: valving said first conduit with movement of said first vane using a lower trailing vane seal affixed to said first vane. 10. The method of claim 9, further comprising the step of: rotating said rotor relative to said housing, wherein said step of rotating results in movement of said first vane, said movement of said first vane valving said first conduit through movement of said lower trailing vane seal. 11. The method of claim 8, further comprising the step of: communicating flow between said first rotor vane slot and said trailing chamber using a vane conduit running through said first vane. 12. The method of claim 11, further comprising the step of: valving said vane conduit with a trailing upper vane seal affixed to said rotor. 13. The method of claim 11, wherein said vane conduit exits said vane through at least one of: a trailing vane side port of said first vane; anda trailing vane wing port of a trailing vane wing of said first vane. 14. The method of claim 13, further comprising the step of: valving using said trailing vane wing, as a function of rotation of said rotor, at least one of:said first conduit; andsaid second conduit. 15. An apparatus, comprising: a housing;a rotor positioned within said housing, said rotor and said housing separated by a chamber; anda movable vane configured to span a distance from a vane slot of said rotor to said housing;a first passage running through said rotor between said chamber and said vane slot; anda second passage running between said chamber and said first passage; anda lower trailing vane seal affixed to said movable vane, said lower trailing vane seal configured to valve said first passage with movement of said movable vane.
