摘要： 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. In order to throw long distance, droplet velocity, droplet size and droplet initial aim angle determine the throw to provide a low precipitation rate (“PR”) for fluidic sprays. The nozzle assembly and method of the present invention achieve a PR of 1 in/hr or less and good spray distribution with a scheduling coefficient (“SC”) of about 1.5 without utilizing any moving components to provide a significantly more cost effective nozzle assembly, as compared to prior art rotator nozzles.

摘要： A fluidic device which produces fluid pulses having a selected pulse repetition frequency, pulse duration, pulse peak pressure and pulse peak flow rate includes first, second and third fluid flow controlling channels or lumens which converge in a junction, defining a “Y” configuration having a base leg and right and left diverging arms. The first leg portion has a fluid input and terminates downstream at the Y junction of the base and the two diverging arms. The first leg has converging walls which reduce the cross sectional area of the flow to thereby increase the fluid velocity to make a fluid jet. The second or right leg, begins at the Y junction and terminates distally in an enclosed, fluid-tight container having a selected blind volume. The third, or left leg, begins at the Y junction and terminates distally in a fluid outlet passage having a selected cross-sectional area.

摘要： A fluidic circuit or oscillator is provided with one or more small raised bumps or protrusions near the outlet or exhaust of a fluidic circuit to alter the spray pattern by re-distributing heavy areas of flow, resulting in a more uniform spray. The fluidic oscillator enclosure operates on a pressurized liquid flowing through the oscillator to generate a liquid jet that flows from said oscillator and into a surrounding environment to form an oscillating spray of liquid droplets, where the oscillator generates a stream of liquid droplets. The outlet or throat structure includes at least one bump or protuberance configured to project into the oscillating spray.
