Abstract: A rotary engine according to the present invention comprises a main housing assembly and a rotor assembly rotatably supported within the housing. The rotor assembly has two rotors, an intake/compression rotor rotatably disposed within the intake/compression housing, and a power/exhaust rotor rotatably disposed within the power/exhaust housing. The rotors have N number of apexes and sides, wherein N is an integer greater than 2. A rotating chamber is formed between each side of the each rotor and the inner wall of the respective housing. The stages of the thermodynamic cycle of the engine occur within these chambers. For example, if the rotors have three sides, the rotors will have a triangular-like shape with three apexes. The apexes form the outermost radial part of the rotors which engage the inner wall of the respective housing bore. Each of these chambers is split into two divided chambers by a reciprocating vane, thereby forming 2 times N divided chambers in each of the respective housing bores.

Abstract: A hinge valved rotary engine has separate compression and expansion chambers with respective smooth surfaced compression and expansion rotors mounted therein on a common engine shaft. The chambers are connected by a combustor unit which receives compressed air from the compression chamber, mixes fuel with the air, and ignites the mixture for communication to the expansion rotor to turn the shaft. Air is compressed by cooperation of a hinged compression valve which sealingly engages the compression rotor. A combustion valve is forced into sealing engagement with the expansion rotor by the pressure of the combustion gases such that the pressurized combustion gases force lobes of the expansion rotor to rotate. A tangentially vaned compressed air control valve in the combustion unit controls the timing of the release of the compressed air into the combustor unit.

Abstract: A rotary internal combustion engine which includes a lobed combustion rotor and a similar compression rotor on a common shaft and firing chambers external to the combustion and compression cavities. The compression rotor compresses excess amounts of air during normal operation which is stored in a tank. During operation, the rotational speed of the engine shaft and the position of an accelerator are sensed. The engine may be run in a non-idle mode by inhibiting the flow of fuel and air to the firing chambers and inhibiting the spark plugs when an idle speed accelerator position and an idle engine speed are sensed, to shut down the engine. When the accelerator is afterwards pressed, the engine is restarted by valving stored compressed air to the combustion cavity to cause the combustion rotor to turn.

Abstract: An external combustion engine including a rotary motor equipped with non-sliding vanes but conformable to the shapes of the envelopes within which they are contained and forced to operate and a combustion member comprising a sleeve in which a piston is free to reciprocate. The two end closures of the sleeve and the piston ends cooperate to form combustion chambers at both ends of the piston strokes. The motor compresses air for admission in the combustion chambers where fuel is burned and is also used for expanding the combusted gas resulting from the fuel combustion. The gas expansion produces more energy than is required to compress the air. The energy difference constitutes the energy yielded by the engine in the form of shaft power. The air admission, the combusted gas exhaust from the combustion member, the fuel injection and ignition are all timely controlled by the piston motion.

Abstract: The unidirectional piston internal combustion engine is composed of a stator and a rotor. Annular grooves are cut on the rotor. Each groove is partitioned with a revolving valve gate to form into one "cylinder" between the rotor and the stator. Pistons are inserted into the cylinders and fixed on the rotor while the valve gates are incorporated in the stator. When the rotor turns, the pistons move relatively with the valve gates, which open to let the pistons pass and close again. The valve gates are operated directly by the pistons. Every two adjacent cylinders are made of a group, one for air compressing and one for combustion and expansion. For each group of cylinders, a one-way air passage valve is provided for compressed air to enter into the combustion and expansion cylinder, and is incorporated in the stator. Inlet and outlet ports are made in the stator. Seals for the valve gates, pistons and between grooves are developed to secure high pressure against leakage.

In a middle section the rotor sucks in air and compresses it towards the other two chambers.
