Abstract: A clog resistant in-line vortex emitter and drip irrigation assembly and method uses a double-sided circuit and a series of vortex chambers of optimized dimensions to create a pressure drop with large dimensions and good clog resistance. The vortex chamber 100 also al lows for a lower exponent than traditional circuits. This gives a pressure regulating property to the no-moving-parts circuit. The vortex emitter allows for some pressure regulation without sacrificing recyclability or requiring moving parts. The vortex circuit of the present disclosure is optimized for an emitter efficiency Ef value wherein Ef=(k/Ackt)*Amin such that k is a unitless head loss coefficient, Ackt is the area of the circuit, and Amin is the minimum cross sectional area of the circuit. A higher k per a given area with larger dimensions allows for a smaller part with a lower chance of clogging.

Abstract: A flow-restricted compound spray generating device 100 includes a spray face member 120B including at least one fluidic circuit oscillator defining geometry 132 including an outlet orifice 138 in the spray face member's central area configured to aim an oscillating spray 300 having a selected oscillating spray thickness distally along a spray axis 112. The spray face member 120B also includes a plurality of non-oscillating (e.g., laminar or jet) spray generating orifices 160B arrayed evenly around the spray face member's periphery to aim a plurality of non-oscillating laminar or jet sprays 302 distally along the spray axis 112 to provide a ring of high velocity streams arrayed around the central oscillating spray 300 to generate a compound spray 310 with an outflow which has a pleasing spray density with an apparent outflow thickness which is substantially equal to the spout orifice's diameter 320.

Abstract: A fluidic nozzle of the scanner type has its outlet spray pattern skewed from its chamber axis (A) by an amount determined by the asymmetry of its outlet orifice (23, 33) about that axis. A spray assembly (70, 90) of such nozzles, such as a showerhead, can be designed using nozzles with selected pattern skew angles to achieve desired spray coverage. Indexing tabs (97) and slots (96) are used to angularly position the nozzles in the showerhead. A portion of each nozzle may be formed with the showerhead faceplate (71) as an integral piece.

Abstract: A fluidic oscillator insert is designed to project a full circumference spray pattern from a single outlet that is characterized by slightly convex or outwardly curving radius and a combination of full and partial protrusions immediately in front of the outlet, in combination with curved walls defining the throat of the outlet (and even outer surfaces of the housing), surprisingly produces full circumference, oscillating spray pattern. Further aspects of the invention include a system and a double exit insert, both of which also produce full circumference oscillating spray patterns.

Abstract: A clog resistant online vortex emitter assembly and method uses a double-sided circuit and a series of vortex chambers of optimized dimensions to create a pressure drop with large dimensions and good clog resistance. The vortex emitter allows for pressure regulation without moving parts and includes a unitary body having a first surface and a second surface opposite the first surface and a multi-lumen flow channel providing fluid communication between the first surface and the second surface, wherein said unitary body is a double-sided circuit with a plurality of vortex chambers with lumens aligned in series. The vortex chamber includes an inlet region, a power nozzle, an interaction region and a throat, the inlet region is in fluid communication with the interaction region through the power nozzle. The plurality of vortex chambers includes dimensions to create a pressure drop and be attached to an outer surface of an irrigation tube.

Abstract: A new scanner fluidic oscillator is used in an economically manufactured fluidic showerhead or nozzle assembly 50, 198, 250, 400 which aims oscillating sprays from multiple scanner fluidics to spread water uniformly over a preselected coverage area. The scanner fluidics and showerhead of the present invention provide a pleasing spray pattern, droplet size, droplet velocity, and temperature uniformity at very low flow rates (i.e., 2 gpm or less) for showering. The scanner fluidics are provided in a plurality of distinct configurations for generating individually tailored scanning sprays having a selected scanning spray characteristics. The showerhead's front plate (e.g., 56, 200, 270, 454) is configured to support and aim the fluidic oscillators, optionally with indexing slots 802 configured to receive corresponding angular indexing tabs 800 on the fluidic oscillator inserts to orient and aim the spray from each fluidic oscillator (e.g., 172, 220,282, 530).
