摘要： 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 orifice 134 defining multiple lip segments 150A, 150B, 150C. Cup-shaped nozzle member 100 has a cylindrical side wall 102 surrounding a central longitudinal axis and has a circular closed end wall with at least one exit aperture passing through the end wall 112. 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 134, where each edge segment is defined at the distal edge of a separate and distinct interior wall segment 160A, 160B, 160C which has a selected wall convergence angle β.

摘要： A very compact nozzle assembly 100, 200, 300 and 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° to 120°. 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.

摘要： A nozzle assembly includes a fluidic oscillator 100 operating on a pressurized fluid to generate an oscillating spray of fluid droplets, and the oscillator aims fluid jets from first, second and third power nozzles 114A, 114B, 114C into an interaction chamber 118 and toward an upwardly projecting island protuberance 126 defining first, second and third island wall segments. The outermost jets 114A, 114B are aimed at an obtuse angle of 100 to 140 degrees along axes which intersect beyond the island at a Jet intersection point, J1. The upstream end of interaction chamber 118 is defined by first and second laterally offset concave wall surfaces 142, 152 which 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 118.
