Title: Innovations of Nicholas R Marchionna
Introduction
Nicholas R Marchionna is an accomplished inventor based in Ann Arbor, MI (US). He holds a total of 3 patents that showcase his contributions to the field of heat engine technology. His innovative designs focus on improving the efficiency and functionality of heat engines, particularly Stirling cycle engines.
Latest Patents
One of his latest patents is the "Heat Engine Rod Seal System." This invention features a pair of rod seals that create a buffer area between a high-pressure zone containing working gas and a low-pressure area of a heat engine. The system utilizes a pump that passively charges with working gas at low pressure and releases it at high pressure when actuated. The working gas may be hydrogen, and the pump can be a thermally actuated metal hydride pump. Additionally, the system includes a mechanism for separating lubricant that collects within the buffer area and reintroducing it into the low-pressure zone.
Another significant patent is the "Heat Engine Combustor." This combustor is designed for use in heat engines, such as Stirling cycle engines, and incorporates multiple nozzles situated between two plates. Fuel is introduced from above the plates into mixing chambers within the nozzles, where combustion inlet air creates a swirling motion in the fuel/air mixture. This mixture then passes through an expansion chamber before entering a common combustion chamber. The combustor is engineered to accommodate high-temperature combustion inlet air while maintaining low NOx emissions.
