ROTARY MACHINE WITH OVAL PISTON IN TRIANGULAR CHAMBER

摘要

A rotary machine preforming a triangular rotation instead of a linear reciprocating motion comprises an oval rotor set of to revolve along a three cylinder walls combined inside a cylinder block to achieve a new combustion moving function of an internal combustion engine with smaller volume, less weight, less parts but stronger power so as serve military vehicle or vessels for better capability and efficiency in the field. The three cylinder walls are incorporated into one unit with a rotor (which serves as a piston in a reciprocating engine) rotating inside the machine. It performs the function approximately three times than a conventional cylinder. Since no linkage is used, the crank and most parts are commonly used, the size can therefore be greatly reduced while the horsepower is relatively increased. Because several intake and exhaust ports can be simultaneously used during each stroke, the efficiency in intaking and exhausting stroke of this machine is greatly improved which means the thermodynamics is fully utilized. The rotor is designed for circulating therethrough with air and engine oil, thereby providing better lubricating and cooling effects. The rotor is constantly in contact with the cylinder walls during its rotary motion around a circle, a high compression ratio is simultaneously achieved as expected.
