Abstract: A fluid motor having a fixed cylindrical casing, supporting a rotor having an output shaft extending rotatably and coaxially in the casing. The rotor includes piston chambers and reciprocable pistons in the piston chamber. A piston rod of each piston is connected to a crankshaft connected to the rotor for rotation therewith. The casing has inlet and outlet ports communicating with the piston chambers during rotation of the rotor to admit compressed fluid through the inlet-port and discharge from the outlet-port. A drive train synchronizes rotation of the crankshafts and the output shaft, a gear tooth ratio of an annular gear to pinion gears on the crankshafts is preferably twice the number of pistons in each rotor block.

Abstract: A compressor having a fixed cylindrical casing, supporting a rotor having an externally driven input shaft extending rotatably and coaxially in the casing. The rotor includes piston chambers and reciprocable pistons in the piston chamber. A piston rod of each piston is connected to a crankshaft connected to the rotor for rotation therewith. The casing has fluid suction and discharge ports communicating with the piston chambers during rotation of the rotor to admit fluid through the suction port and discharge compressed fluid from the discharge port. A drive train synchronizes rotation of the crankshafts and the input shaft, a gear tooth ratio of an annular gear to pinion gears on the crankshafts is preferably twice the number of pistons in each rotor block.

Abstract: An internal combustion rotary engine of the type comprising a rotor, an output shaft as the rotor axis, crankshafts mounting on output shaft, pistons reciprocable in piston chambers within the rotor, piston rods connecting the pistons to the crank of crankshaft. This rotary engine is characterized by the ignition force perpendicular to the output shaft radius, by radially spaced the crankshaft axis from output shaft axis, by connection between the output shaft and the crankshafts to concurrently synchronize them.
