Latest Patents

James F. Duncan holds a patent for a Multi-function simplex/prefilmer nozzle. This innovative spray nozzle serves dual purposes: it acts as a cooling device to introduce a fluid into the engine's fluid stream and as a cleaning device to facilitate the cleaning of internal engine components. The nozzle features a multi-layered arrangement of etched plates that define flow paths for both the first and second fluids. Non-radial feed slots direct the first fluid into a cylindrical swirl chamber, allowing for optimal fluid dynamics. The swirling fluid can exit through either a spray orifice or a prefilmer, depending on the nozzle's configuration. Additionally, the design incorporates non-radial feed slots that direct the second fluid inward, downstream of the first fluid, creating a fine dispersion of droplets for effective cooling. During cleaning operations, only the first fluid is introduced, resulting in larger droplet sizes that are more suitable for cleaning internal engine components.
