Title: Innovations of Brian D Mallen
Introduction
Brian D Mallen is a notable inventor based in Charlottesville, VA, with a remarkable portfolio of 16 patents. His work primarily focuses on advancements in rotary vane technology, which has significant implications for efficiency and environmental sustainability.
Latest Patents
Among his latest innovations is the "Vane pumping machine utilizing invar-class alloys for maximizing operating performance and reducing pollution emissions." This invention features a rotary-vane pumping machine with a core structure that includes a stator assembly defining a contoured surface of a stator cavity. The rotor spins around a fixed rotor shaft axis, and end plates are positioned on either side of the rotor. The rotor contains multiple radial vane slots that house corresponding vanes, which slide within these slots. Each vane is designed with side walls, a tip portion, and a base portion, which includes tabs extending from at least one axial end. The design allows for precise non-contact sealing clearances between components, thanks to the use of low coefficient of thermal expansion Invar materials.
Another significant patent is the "Variable bandwidth striated charge for use in a rotary vane pumping machine." This rotary vane combustion engine incorporates a rotor with several vanes and a stator that encloses the rotor, forming multiple vane cells. It features intake and exhaust ports for managing the flow of fuel and air. The innovation allows for a discrete band of mixed fuel and air to be delivered to each vane cell, enhancing efficiency by eliminating vacuum pumping losses.
