William Bennett Ribbens

A rotary engine includes a housing and elliptical rotors mounted to rotor shafts for rotation within a chamber of the housing. A valve disk mounted to a rotor shaft includes a port passing between first and second sides. A valve plate includes a bore defining a cylindrical sidewall for rotationally receiving the valve disk. The valve disk includes a groove disposed in a wall, and includes a ring member disposed in the groove that contacts the sidewall of the bore when the valve disk is disposed in the bore. The apparatus may include multiple valve disks disposed in separate bores to operate as exhaust or intake valves. Circumferential channels may be included in the bore sidewalls within which the ring members are disposed.
