Abstract:
A rotary internal combustion engine, comprising:a body with an inner cylindrical cavity, and having a first inlet channel, a first outlet channel, a second inlet channel, a second outlet channel, an exhaust channel and an intake channel disposed therein; side covers; a rotor-piston concentrically mounted in the inner cylindrical cavity, and having side surfaces, and having a periphery surface with radial protrusions and radial recesses thereon, said rotor-piston forming together with said body, segment cavities, the side surfaces of said rotor-piston abutting tightly against said side covers, said radial protrusions abutting tightly against an inner cylindrical surface of said body which defines the inner cylindrical cavity; at least one pair of combustion chambers, including a first combustion chamber, and a second combustion chamber which is identical to said first combustion chamber and isolated therefrom, said first combustion chamber communicating with the inner cylindrical cavity of said body through the first inlet channel and through the first outlet channel, said second combustion chamber communicating with said inner cylindrical cavity of said body through the second inlet channel and through the second outlet channel, each of the first inlet channel, the first outlet channel, the second inlet channel and the second outlet channel having a controlled valve; a control mechanism; a first separation vane mounted between the inlet channels of the pair of combustion chambers and the outlet channels of the pair of combustion chambers, and being connected to said control mechanism so as to radially displace in grooves formed in said body and in grooves formed in inner surfaces of said side covers; and a second separation vane mounted between the exhaust channel and the intake channel and being connected to said control mechanism so as to radially displace in further grooves formed in said body and in further grooves formed in the inner surfaces of said side covers, said first and second separation vanes being brought into contact with the periphery surface of the rotor-piston to define together with said radial recesses of said rotor-piston, with said inner cylindrical surface of said body and with said side covers, segmented working chambers.
