ABSTRACT:
A rotary engine with one or more toroidal chambers defined by rotors that rotate within cylindrical housings. Pistons project into the chambers from the rotors. The pistons cooperate with valves to define compression regions and expansion regions in the chambers. The rotors, the pistons, the valves, or a combination thereof define or include combustion regions of constant volume wherein a fuel-air mixture compressed in the compression regions burns and then is ejected to the expansion regions. Fuel is injected into both the compression regions and the expansion regions. In a first embodiment of the engine, the valves are rotary and include recesses that accommodate the pistons as the pistons pass the valves. As a piston transits from a compression region to an expansion region via a valve, the space in the valve recess not occupied by the piston is the combustion region. In a second embodiment of the engine, the motion of two pistons in two chambers is coordinated so that as one piston arrives at the end of a compression region of its chamber and the other piston enters an expansion region of its chamber, the volume between the two pistons is the combustion region. In a third embodiment of the engine, the combustion region is enclosed by two tandem rotary valves of two different chambers. In a fourth embodiment, the combustion regions are in rotary combustion chambers inside the pistons or inside the rotors.
