摘要： A multi-function spray nozzle for engine applications useful as a cooling device to introduce a fluid into the fluid stream of the engine, and as a cleaning device to introduce a fluid to clean internal components of the engine. The nozzle includes a multi-layered arrangement of etched plates defining flow paths for the first and second fluids. Non-radial feed slots direct the first fluid into a cylindrical swirl chamber. The swirling fluid exits the swirl chamber through a spray orifice or a prefilmer, depending on whether the nozzle is configured as a simplex or prefilmer nozzle. Other non-radial feed slots direct the second fluid inward, downstream of the first fluid, to create a fine dispersion of droplets for fluid stream cooling purposes. During cleaning, only the first fluid is introduced through the nozzle, which results in a larger droplet size suitable for cleaning purposes of the internal components of the engine.
