Title: Internal combustion engine with gyratory piston and cylinder movement

Abstract: An internal combustion engine wherein a piston element with rectilinear sides operates within a movable cylinder-piston element having rectilinear sidewalls, and wherein the combustion chamber has a polyhedral shape. Rotatable crankshafts are mounted in each of the piston and cylinder-piston elements so that said elements follow gyratory paths in opposite directions to effect a variable volume combustion chamber. A cylindrical valve member is rotated in timed sequence to the rotation of the crankshafts so that intake and exhaust ports are sequentially opened and closed during the combustion cycles. One or both of the crankshafts may operate or be joined to a drive shaft or shafts for work output, said crankshafts being interconnected by gear means to coordinate gyratory movement of the piston and cylinder-piston elements.
