Abstract: A steam enhanced dual piston cycle engine utilizes a unique dual piston apparatus that includes: a first cylinder housing a first piston therein, wherein the first piston performs only intake and compression strokes; a second cylinder housing an inner power piston that forms an inner internal chamber of the second cylinder, and either a ring-shaped outer power piston surrounding the inner power piston, wherein the outer power piston forms an outer internal chamber of the second cylinder and is configured to convert engine heat into additional work, and/or an outer boiler which is configured to produce steam to be converted into additional work.

Abstract: A Dual Piston Cycle Engine utilizes a unique dual piston apparatus that includes: a first cylinder housing a first piston therein; a second cylinder thermally isolated from the first cylinder and housing a second piston therein; an intake valve coupled to the first cylinder for allowing a fuel mixture to enter into the first cylinder; an exhaust valve coupled to the second cylinder for allowing an exhaust gas to exit the second cylinder; and an interstage valve that couples an internal chamber of the first cylinder to an internal chamber of the second cylinder and configured to minimize dead space between the first and second cylinders, wherein the first piston performs only intake and compression strokes and the second piston performs only combustion and exhaust strokes and the first and second cylinders are thermally isolated from one another.

Abstract: Prior art linear bearings generally have a roller element which, in such a reciprocating motion application, tend to creep or slide along the surfaces upon which they roll. This is due to unequal frictional forces between the rolling surfaces. The linear bearing of the present invention substantially prevents straying and/or sliding of roller elements, and therefore provides bearing functionality at high speeds and great loads with longer longevity and reliability. The linear bearing can be used in many engineering applications, such as in a rotary engine, for example.

Abstract: A rotary motor with a pair of abutments that move relative to a rotor through the rotation of gears operatively connected to both the abutments and the rotor. The abutments and rotor are located within a housing such that the inner cavity of the housing is divided into four chambers. The rotor has a pair of blade sections that are in constant contact with the motor housing, so that the chambers are always sealed from each other. Also connected to the housing are a pair of intake ports and a pair of exhaust ports. The rotor rotates within the inner cavity pushing air from the intake ports to the exhaust ports. The abutments are constructed to move in a linear direction, to allow the blade sections to rotate from one chamber to another. The movement of the abutments is synchronous with the rotation of the rotor, so that the abutments are always in contact with the rotor to insure that there is negligible fluid communication between chambers.
