Abstract: An improved sealing means for internal combustion engines comprising a combination of a metal primary sealing ring positioned substantially within a groove on the piston, and a compliant secondary sealing ring positioned in the groove behind the primary compression ring so that the compressed combustion gases force the compliant secondary sealing ring to form a seal between the groove and the primary sealing ring. In the preferred embodiment, the gapped ring is non-planar in order to provide effective sealing in a ported fixed-piston, rotating and translating cylinder engine such as the Deckard engine. Alternate embodiments include gapless rings with only a primary compression ring, and gapless rings with a compliant secondary sealing ring. An alternate embodiment is a single piece metal-capped compliant secondary sealing ring.

Abstract: A rotary disc having at least two radial concave portions and two radial convex portions on one end is opposed at the concave/convex surface to a concave/convex surface of a non-rotary disc having the concave/convex surface of the same shape, and one of the discs is made axially slidably and engaged to the other resiliently. Two variable volume chambers formed between the concave/convex surfaces of the two disc are used as a set of engine chambers in which a suction port is disposed to a slope of the first chamber on the side that the concave/convex surfaces of discs get into engagement, and the exhaust port is disposed to the slope of the second chamber on the side that the concave/convex surfaces of discs get out of the engagement. A gas reservoir combustion chamber communicating by way of a compression communication channel is disposed between the first chamber and the second chamber, and the compression stroke and the exhaust stroke are conducted simultaneously, while the expansion stroke and the suction stroke are conducted simultaneously in the two concave portions of the rotary disc passing through the two chambers.

Abstract: The apparatus of the invention relates to a free piston Stirling engine that contains a power piston and a displacer piston which each reciprocate in a coaxial cylinder. At least one piston is hydrodynamically lubricated to avoid friction based wear by spinning the piston about its axis through the utilization of at least one magnetic article mounted onto one of the interfacing wall surfaces. The article magnetically interacts with a track made of magnetic material mounted on the opposing, interfacing surface so that during operation the interaction creates a torque which spins the piston about its axis and causes the desired lubrication to take place.

Abstract: A free piston combustion chamber coupled to air compression and gas expansion chambers are combined with a rotary motor. The rotary motor shaft drives the air compressor, receives power from the expanding gases in the expansion chamber and provides residual torque and power for external use. Two combustion chambers located at each end of the free piston receive compressed air and fuel for combustion outside of the rotary motor assembly. The motion of the free piston between the two combustion chambers is independent of the motor rotary motion. The air admission inside the combustion chambers, the fuel injection and the combustion initiation process are all controlled and timed by the free piston movement back and forth. A heat exchanger is located between the combustion-chamber/free-piston assembly and the rotary motor. The compressed air exiting from the compression chamber is heated by the gases exiting from the combustion chambers, before they are admitted into the expansion chamber of the rotary motor. The heat exchanger also performs the function of a pressurized pressure vessel or reservoir to smooth out pressure surges in the compressed air or gases entering or leaving the combustion chambers. The power output of the rotary motor is determined by the control of the amount of air or of the amount of fuel admitted in the combustion chambers. Air and fuel admissions can also be controlled simultaneously in a programmed manner. The two combustion chambers can also be formed alternatively by two oscillating free pistons guided inside a quasi torodoidally shaped containing structure.

Abstract: External combustion engine which comprises a first cylinder and a second cylinder, in which a first piston and a second piston are able to slide respectively. The first and second cylinder are fluidically connected with respect to each other for the passage of a heat-carrying fluid suitable to determine the cyclical movement of the first piston and the second piston. The external combustion engine also comprises a drive shaft rotating around an axis of rotation, and with which crank means are solidly associated, provided with at least a first pin and a second pin having pivoting axes parallel to each other, and also disposed distanced radially from the axis of rotation. The external combustion engine also comprises first and second kinematic connection means suitable to connect respectively the first pin and the second pin to the first piston and respectively to the second piston. The first pin and the second pin are disposed with the respective pivoting axes angularly offset so as to be angled by a desired angular amplitude equal to a first acute angle with respect to the axis of rotation.
