Latest Patents
One of his latest patents is the "Electric actuator for swashplate." This invention involves an actuating mechanism designed to control the swashplate angle in a Stirling cycle engine or other engines featuring parallel reciprocating pistons. The actuation system utilizes an electric motor to change the swashplate angle. Various embodiments of gear trains are described, including a planet gear carrier driven by the motor, which meshes with two ring gears of differing teeth counts. This configuration allows for a high reduction drive for the second ring gear. Other embodiments include a freely rotating ring gear carrier and a driving sun gear, as well as a combination of features from previous designs to minimize friction.
Another significant patent is the "Shell and tube heat pipe condenser." This invention presents an improved conduit assembly that connects a heat pipe evaporator with a Stirling engine heat exchanger. The assembly features a cylindrical main tube section linked to a flared shell, which increases the cross-sectional area to reduce the velocity of vaporized heat pipe working fluid. This design minimizes the entrainment of liquid within the vapor. Additionally, the assembly includes a small diameter liquid return duct and surface tension breakers to enhance the separation of liquid and vapor phases, ensuring efficient operation.
