Patent ID: 8230836

Claim:
A rotatably reciprocating multi-cylinder vane internal combustion engine comprising: a multitude of cylindrical casings; longitudinally extending walls being affixed inside said casings; end plates for each casing; power output rotary shafts mounted within said casings upon said end plates, affixed to swinging vanes; a multitude of chambers, two inside each cylindrical casing, formed between said longitudinally extending walls and between said vanes, working in a combination of couples and complementing each other as one charging and one ignition chamber; wherein said vanes rotatably alternate in back and forth fashion in such a manner that the volume of said chambers between said vanes and the walls compresses and expands in a sequence of a two-stroke mode in which the internal combustion engine operates; wherein each one of charging chambers is sequentially operating in a stroke of intake of combustible fuel-air mixture, and then in a reversed stroke of expulsion of said mixture; said each one of the charging chambers further comprising: intake ports for an additional fuel mixture; exit ports and conduits connected to said exit ports for transfer of said additional fuel mixture into the ignition chambers; wherein each one of ignition chambers burns the compressed fuel-air mixture; said each one of the ignition chambers further comprising: intake ports connected to said conduits for delivering of said additional fuel mixture from said corresponding charging chamber; and exhaust ports for the exit of the burned gases thereafter; wherein each one of said working chambers contains ignition means which fire sequentially therefore operating said engine in strokes of intake-and-compression, and then in reversed strokes of expulsion-and-exhaust.
