Abstract
An internal combustion engine has a ring-shaped stator with a plurality of thin slits. A rotor, having a plurality of helicotoroidal troughs formed on its inner surface, encloses the stator. A planar vane wheel, having a plurality of radially extending vanes, is resident in each of the thin slits, with the vanes communicating with the respective helicotoroidal troughs. Rotation of the rotor imparts rotation to the vane wheels. The interaction of the stator, troughs, and vanes produces a plurality of sequential intake, compression, combustion, expansion, and exhaust chambers.
