Rotary internal combustion engine

Abstract

An internal combustion rotary engine is provided for producing mechanical torque. The engine includes an annular planar housing, a rotor, sparkplugs, flap valves, an axial shaft and fore-and-aft covers. The housing includes a quadrilateral symmetry including a substantially circular annulus flanked by first and second cavities. The rotor has a cam block sandwiched between fore and aft circular wings. The sparkplugs are respectively accessible to the second cavities. The flap valves rock within the respective cavities and within the cam block. Each valve includes indents to pass around the wings. The fuel intake provides fuel to the cavities. The axial shaft rotates the rotor within the housing. Covers, each having a center orifice and a pair of ports exposed to ambient and respectively adjacent the first and second cavities. The wings intermittently block at least one port while the rotor rotates.
