Patent ID: 7182061

Claim:
A rotary internal combustion engine comprising: a) at least one chamber having an interior comprising a toroidal path of travel, b) a housing disposed in outwardly spaced, at least partially surrounding relation to said chamber, c) an intake assembly and an exhaust assembly each structured to define fluid communication between said interior and an exterior of said chamber, d) an interacting piston assembly comprising at least a first piston and a second piston each movable within said interior along said toroidal path of travel, e) said first piston connected in driving relation to a power take-off and said second piston positionable in driving relation to said first piston, f) said first and second pistons cooperatively structured and relatively disposed to accomplish intake, compression, ignition and exhaust phases of an engine cycle during forced travel of said first piston along said toroidal path of travel, g) a restricting assembly disposed in interconnecting relation between said second piston and said chamber and structured to at least partially restrict movement of said second piston at a predetermined location along said toroidal path of travel, and h) said restricting assembly comprising at least one restricting member interconnected to said second piston and movable therewith, said restricting assembly further comprising a blocking assembly disposed in interruptive relation to, said restricting member as said second piston moves along said toroidal path of travel.
