A nozzle assembly includes a fluidic oscillatoroperating on a pressurized fluid to generate an oscillating spray of fluid droplets, and the oscillator aims fluid jets from first, second and third power nozzlesA,B,C into an interaction chamberand toward an upwardly projecting island protuberancedefining first, second and third island wall segments. The outermost jetsA,B are aimed at an obtuse angle of 100 to 140 degrees along axes which intersect beyond the island at a Jet intersection point, J. The upstream end of interaction chamberis defined by first and second laterally offset concave wall surfaceswhich define left side and right side vortex generating areas so that fluid jet steering vortices may be alternately formed and then displaced distally and shed to steer the fluid jet laterally within interaction chamber

Three-jet fluidic oscillator circuit, method and nozzle assembly

A nozzle and spray dispenser for generating a uniform substantially flat fan spray pattern when spraying high viscosity fluids (i.e., oils, lotions, cleaning liquids, shear-thinning liquids and gels and similar Newtonian and non-Newtonian fluids having viscosities of 10-100 cP) is configured with an exit orificedefining multiple lip segmentsA,B,C. Cup-shaped nozzle memberhas a cylindrical side wallsurrounding a central longitudinal axis and has a circular closed end wall with at least one exit aperture passing through the end wall. At least one enhanced exit orifice structure is formed in an inner surface of the end wall, and includes two to five lip segments of selected width defining edges at the orifice, where each edge segment is defined at the distal edge of a separate and distinct interior wall segmentA,B,C which has a selected wall convergence angle &#x3b2;.

Spray nozzle for high viscosity spray applications with uniform spray distribution

A very compact nozzle assemblyand spray head for an automotive washer nozzle is configured for inclusion into an automotive trim component. The compact nozzle assembly and spray head generate a very effective cleaning spray at a selected spray fan angle, yaw angle and roll angle and, in an exemplary embodiment, the spray fan is dual shear shaped, producing an even distribution, which may be varied from 30&#xb0; to 120&#xb0;. Spray head may be as small as 5 mm in diameter and be aimed to provide a spray with various spray aim, yaw and roll angles. The design accounts for better mold ability and versatility of application.
