An orbital engine with a first outer generally tubular body with a first axis, and a second generally tubular inner orbiter body with a second axis, the second inner body being moveable within the first outer body. The first and second axes are parallel, but not colinear. The second inner body revolves, but does not rotate, within the first outer body Vanes extending generally radially relative to both the inner and outer bodies define multiple chambers in the space between the outside of the inner body and the inside of the outer body. The vanes reciprocate relative to both the inner and outer bodies, and no vane traverses the entire inner surface of the outer body. When fitted with ports in the outer body and valves, the orbital engine may be implemented as an internal combustion engine, gas compressor, liquid pump, air motor, blower, fan or turbine, etc.

1. An orbital engine with a first outer generally tubular body with two outer body ends and an inside, said first outer body being stationary and having a first axis, a second generally tubular inner body with an outside and a second axis, the second inner body being contained and movable within the stationary first outer body, said first and second axes being parallel, but not colinear, the second inner body having a crank with two ends, one of said two crank ends being connected to the second inner body at the second axis, and the other of said two crank ends extending through one of the two outer body ends and being connected to a drive sprocket at the first axis of the first outer body, there being a plurality of vanes extending in slots generally radially relative to both inner and outer bodies, from the inside of the first outer body to the outside of the second inner body, said vanes and said two outer body ends defining a plurality of chambers in a space between the outside of the inner body and the inside of the outer body, the vanes being slidably movable within the slots and reciprocally movable relative to both the inner and outer bodies, so that rotation of the crank or the drive sprocket results in the orbiting, but not rotation, of the second inner body within the stationary first outer body. 2. The orbital engine of claim 1 wherein the plurality of chambers is an even number. 3. The orbital engine of claim 1 wherein the plurality of chambers is an odd number. 4. The orbital engine of claim 1 wherein the second inner body has two cranks. 5. The orbital engine of claim 4 wherein each of the two cranks is connected to one of two sprockets. 6. The orbital engine of claim 1 wherein the vanes slide in and out of slots in the second inner body, and press against the inside of the first outer body. 7. The orbital engine of claim 1 wherein a chamber has a spark plug. 8. The orbital engine of claim 7 wherein each chamber has a spark plug. 9. The orbital engine of claim 6 wherein the vanes reciprocate on a flat surface on the inside of the first outer body. 10. The orbital engine of claim 1 wherein the vanes do not rotate around the full perimeter of the inside of the first outer body.
