As attorney for the inventor of the innovative Rotary Engine we are currently seeking manufacturing companies to license, purchase patent rights or enter into a royalty agreement for this timely invention.

The present invention relates generally to internal-intermittent-combustion engines, and more specifically to toroidal rotary engines. The invention will provide a toroidal rotary engine which is smaller, lighter, more completely free of vibration, cheaper, and mechanically simpler than the reciprocating internal-combustion engine.

Objects of the present invention:

to provide a toroidal rotary engine including a simple control mechanism, an acceptable sealing of the sliding surfaces involved and a reliable, simple connection between the toroidal pistons and output shaft
to provide a toroidal rotary engine that allows the fitness of a two or a four-stroke cycle with a spark-ignition or a compression-ignition system
to provide a toroidal rotary engine that is smaller, lighter, more completely free of vibration, cheaper, and mechanically simpler than the reciprocating linear internal-combustion engine
to provide a toroidal rotary engine that is simple and easy to use
to provide a toroidal rotary engine that is economical in cost to manufacture

The following pictures are meant to display possible physical characteristics of the present invention and are not to be taken in a limiting sense. It is understood that other embodiments may be utilized and that structural changes may be made without departing from the scope of the invention.
