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.

Abstract: A long throw Pop-Up Irrigation Nozzle assembly has no oscillating or rotating parts and includes a cylindrical body having a fluid inlet and a sidewall defining at least one fluidic circuit configured to generate a selected spray pattern when irrigation fluid flows through the body.

Abstract: A full coverage fluidic oscillator (2) includes a fluidic circuit member preferably having an oscillation inducing internal chamber, at least one inlet (8) or source of fluid under pressure, at least a pair of output nozzles (14, 16) connected to the source of fluid for projecting at least first and second impinging fluid jets into free space, where the first and second impinging jets collide or impinge upon one another at a selected jet angle to generate a substantially omni-directional sheet jet having selected thickness. The first and second jets are aimed at a pre-selected intersection point in free space where impingement is to occur. The sheet jet's thickness Δy is determined by the time-varying path or oscillation of each of the first and second impinging jets. The first and second impinging jets can be made to oscillate or pulsate by use of vortex generating amplifier structures (68, 70, 72, 149) within the internal chamber's fluid flow paths.
