  • Rotary piston internal combustion engine
    Patent number: 4194871
    Abstract: The engine of the present invention provides a pair of piston members which rotate intermittently relative to one another within a cylindrical chamber. The piston members' intermittent rotation provides intake, compression, firing and expansion, and exhaust processes for the spaces or chambers formed in the cylindrical chamber between the piston members. The engine includes an output shaft and a mechanism for controlling the motions of the piston members relative one another and to translate or convert the non-uniform or intermittent motion of the piston members to a uniform rotation of the output shaft.
