Abstract: The invention relates to various low flow rate fluidic nozzle inserts having a reverse mushroom-shaped mushroom insert geometry that are useful for a wide range of spraying and cleaning applications. In one embodiment, the present invention relates to fluidic nozzle inserts that are able to perform at low flow rates with geometrical and dimensional limitations. In still another embodiment, the present invention relates to compact fluidic nozzle inserts that provide a manner by which to attain a desired level of performance in a fluidic nozzle assembly for small scale applications at low flow rates.

Abstract: A conformal, cup-shaped fluidic nozzle engineered to generate an oscillating spray is configured as a (e.g., 100, 400, 600 or 700). Preferably, the fluidic circuit's oscillation inducing geometry 710 is molded directly into the cup's interior wall surfaces and the one-piece fluidic cup may then fitted into an actuator (e.g., 340). The fluidic cup (e.g., 100, 400, 600 or 700) conforms to the actuator stem used in typical aerosol sprayers and trigger sprayers and so replaces the prior art “swirl cup” 70 that goes over the actuator stem (e.g., 320), With the fluidic cup (e.g., 100, 400, 600 or 700) and method of the present invention, vendors of liquid products and fluids sold in commercial aerosol sprayers 20 and trigger sprayers 800 can now provide very specifically tailored or customized sprays.
