Additionally, a rotor assembly is eccentrically and rotatably mounted about the stator core and having a pair of partial sidewalls, each of which defines a circular opening. A pair of shaft seals, in which each shaft seal is set into one of the circular openings and are rotatably mounted about the tube.

Finally, ignition, intake and exhaust mechanisms are mounted internal to the hollow stator core.

Abstract: This invention relates to novel reciprocating shuttle inlet valves, effective with every type of two-cycle engine, from small high-speed single cylinder model engines, to large low-speed multiple cylinder engines, employing spark or compression ignition. Also permitting the elimination of out-of-phase piston arrangements to control scavenging and supercharging of opposed-piston engines. The reciprocating shuttle inlet valve (32) and its operating mechanism (34) is constructed as a single and simple uncomplicated member, in combination with the lost-motion abutments, (46) and (48), formed in a piston skirt, obviating the need for any complex mechanisms or auxiliary drives, unaffected by heat, friction, wear or inertial forces.

Abstract: A rotary engine includes separate chambers for receiving pressurized air and fuel. An air chamber stories pressurized air that is routed into a combustion chamber to be mixed with fuel for combustion to drive a piston. The combustion chamber is forced open during a firing cycle to allow expanding gases into a piston chamber. A valve door serves as a base against which the expanding gases react to force a piston in a forward direction. The piston is coupled to a crank shaft which may in turn be coupled to a transmission or other power drive device to harness energy created by the turning crankshaft. A lifter includes a gear that rotates to raise and lower the valve door such that it moves towards and away from the crankshaft to optimize the amount of energy that is directed against the piston. Through series of multiplier gears, the amount of movement necessary to lift the door is minimal.

The second stroke is a power stroke where the uncompressed intake products are ignited to produce combustive products. The third stroke is an exhaust stroke where the combustive products are exhausted from the combustion engine.

Abstract: A rotary internal combustion engine comprises a four-segment hinged rotor assembly accommodated in a coaxial housing such that the rotor assembles deforms and continuously adapts to the housing internal profile during its rotation. The closed non-circular rotor housing internal profile is a curve defined by a novel mathematical relationship. The curve is the locus of all points generated by the base extremities A and B of an isosceles right angle translating and simultaneously rotating triangle with the following constraints. The center point P of the base AB (of length c) of the triangle must always be located on an inscribed circle of radius c/2 and center at point O. The vertex C of the triangle must always be located on one of the four lobes of the curve of the form r=sin(2&thgr;) where angle &thgr; is the angle between line OA and the positive vertical (y) axis and also line OB and the positive horizontal (x) axis.

Abstract: This invention is a hybrid steam & combustion rotary engine designed to use combustion to drive a piston in a continious unidirectional circle within a sealed toroidal chamber. Combustion drives the piston(s) and the heat is utilized to create steam by water injection to induce cooling & extra thrust on the piston(s) within the toroidal chamber(s). Magnetically sensitive pistons are magnetically coupled to a drive axle through the nonmagnetic chamber walls, eleminating the need for combustion seals within the pressure chambers. Tempreature & piston locations are monitored by common tempreature and magnetic sensors located outside the toroidal chambers. The valve opening & closings, as well as ignition, water & fuel injection, are controlled via a common micro-processor.

Abstract: A torque transmission device includes a pulley, a cylindrical member, a torque limiter and a weight member. The pulley is rotated by torque transmitted from a drive source. The cylindrical member is connected to a rotatable shaft of a compressor and is rotated integrally with the rotatable shaft. The torque limiter is arranged between the pulley and the cylindrical member and transmits the torque from the pulley to the cylindrical member. The torque limiter disables the transmission of the torque when the torque becomes equal to or greater than a predetermined value. The weight member is secured to the cylindrical member at a point closer to the rotatable shaft than the torque limiter.

Abstract: The engine includes a housing having a circular cavity with a rotatable flywheel defining a radially extending power piston(s) disposed therein. An abutment disc connects to a compression piston rotor and rotates synchronously with the flywheel. Compression piston(s) rotate on separate axes within the compression piston rotor and move in and out with respect to the outer periphery of the compression piston rotor. A compression piston stator seals off the top of the compression piston rotor causing the compression pistons to compress a charge of gas to be delivered on top of the power piston(s). Fuel is injected and the combustion zone is ignited. The expanding gases force the power piston(s) and flywheel around the housing producing work. The previous products of combustion are forced out the exhaust system in front of the power piston.

Abstract: The efficiency of a vehicle having a body and a reciprocating piston four-stroke internal combustion engine is increased substantially by greatly reducing the size of the engine relative to the weight of the body. The great reduction in engine size relative to the weight of the body causes the engine to operate in a much more efficient range during almost all of the time of its operation. Peak power needs are satisfied by turbocharging and varying the compression ratio.
