ABSTRACT:
A concentric, valveless internal combustion engine is provided, consisting essentially of a rotary piston which revolves in a casing about a central shaft. The rotary piston contains combustion cavities distributed equidistantly around its perimetral wall surface. The casing contains combustion chambers and adjoining exhaust ports, and fuel intake manifolds in spaced relationship from one another. One or more means for igniting the fuel mixture is/are distributed at spaced intervals which are designed to provide timed ignitions of the fuel mixtures. Means are provided for starting the engine's rotation, and for feeding it a fuel-air mixture. As the piston rotates it carries the fuel mixture from the intakes to the points of fuel ignition, then to combustion chambers where the ignited fuel gases expand rapidly, and next to ports where the gases are exhausted from the engine. As the gases are formed the explosive force of their expansion against a certain portion of the engine housing and certain unique gate members causes the piston to rotate around the central shaft. The gate members are situated adjacent each combustion cavity. These gates are mounted for reciprocal movement radially into and out from the peripheral wall surface of the rotor. Sealing elements on the gates enable the gates to sweep the fuel-mixture to the combustion cavities, the gases being compressed en route with the help of shaped manifolds in the housing wall, and to sweep the burnt gases out of the combustion cavities and expansion chamber into and out through the exhaust ports.
