Title: The Innovative Contributions of William H. Houtman
Introduction
William H. Houtman is a notable inventor based in Ann Arbor, MI, with a remarkable portfolio of 11 patents. His work primarily focuses on advancements in Stirling engine technology, showcasing his commitment to innovation in the field of thermal motors.
Latest Patents
Among his latest patents, Houtman has developed a Stirling engine with a swashplate actuator. This hydraulic actuator enables modulation of the engine's displacement, incorporating a rotary vane configuration that allows for relative rotational adjustments between components of a swashplate assembly. This innovation provides adjustments to the angle formed by the swashplate relative to its angle of rotation, thereby varying the stroke of each piston connecting rod and modulating the swept volume of the respective piston within its cylinder bore. Another significant patent is the heat engine heater head assembly designed for multi-cylinder heat engines, such as the Stirling engine. This assembly features a plurality of regenerators and cylinders, with first and second identical cast heater tubes connecting the regenerator manifold to the heater head manifold and the cylinder manifold, respectively. The heater tubes are designed to be rotationally asymmetric, enhancing their efficiency.
