    摘要： A conformal, cup-shaped fluidic oscillator spray nozzle member (100, 200, 300, 400, 500) is configured to generate one or more oscillating sprays from fluid flowing into a substantially open proximal end and distally into a substantially closed distal end wall with one or more centrally located orifices defined therein. A multi-input, multi-output cup-shaped fluidic oscillator ( 200, 300, 400) is configured to generate a selected fluid spray from a plurality of (e.g., 2-8) fluid product inlets which are configured in interacting pairs and feed into a common interaction region of the fluidic nozzle geometry. Optionally, an outlet "A" can be positioned in the interaction region and allow for air entrainment into the interaction region or external oscillating spray streams to generate a foamed spray of fluid product.

    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 spray dispenser is configured to generate a swirled output spray pattern 152 with improved rotating or angular velocity ω and smaller sprayed droplet size. Cup-shaped nozzle member 60 has a cylindrical side wall 62 surrounding a central longitudinal axis 64 and has a circular closed end wall 68 with at least one exit aperture 74 passing through the end wall. At least one enhanced swirl inducing mist generating structure is formed in an inner surface 70 of the end wall, and including a pair of opposed inwardly tapered offset power nozzle channels 80, 82 terminating in an interaction chamber 84 surrounding the exit aperture 74. The power nozzle channels generate opposing offset flows which are aimed to very efficiently generate a vortex of fluid which projects distally from the exit aperture as a swirled spray of small droplets 152 having a rapid angular velocity.

    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.
