Abstract:
A rotary engine comprising:a hollow cylinder having a cylinder axis with a longitudinal rod extending there along, and an interior surface; a rotor mounted within the cylinder, said rotor rotatable about a rotor axis parallel to the cylinder axis of the cylinder, said rotor axis non-colinear with the cylinder axis, and said rotor axis fixedly positioned relative to the cylinder axis and located along a first radial extending from the rotor axis to the interior surface of the cylinder; a main shaft connected to the rotor, said main shaft located along the rotor axis; a plurality of vanes connected to the longitudinal rod and extending to the interior surface of the cylinder, said vanes each having a vane axis, wherein adjacent vanes of the plurality of vanes and the interior surface of the cylinder define cavities respectively, said cavities having a volume, and the volume of one of the cavities intersected by the first radial is the smallest of the cavity volumes; a plurality of wigglets cooperating with the plurality of vanes, each of said wigglets connected to the rotor and receiving a respective vane at the rotor and allowing the vane to extend through the wigglet while allowing at least one of the vane and the rotor to move along the vane axis and allowing relative rotation of the vane relative to the rotor at the wigglet; and a plurality of valves connected to the cylinder for selectively controlling fluid flow to and from the cavities.
