    摘要: Spray nozzle assembly (300) is configured to generate a swirled spray (312) with improved rotating velocity ω and smaller uniform droplet size. Cup-shaped nozzle member (300) has a body portion (318) with a cylindrical side wall (320) surrounding a central longitudinal spray axis (322), a circular closed end wall (324) and an exit aperture (310) coaxial with the spray axis (322) and defined through the end wall (324). A fluid dynamic circuit (330) is formed in an inner surface (326) of end wall (324) and includes three inwardly tapered power nozzles (302, 304, 306) terminating in an interaction region (308) which is exhausted via the exit aperture (310). The power nozzles have respective longitudinal axes (334, 362, 382) offset with respect to the spray axis (322) with corresponding non-tangential angles of attack (352, 374, 394) configured to efficiently cause a fluid vortex in interaction region (308).

    摘要: A micro-sized structure and construction method for a fluidic oscillator wash or spray nozzle (100 or 250) has a nozzle housing (110 or 252) enclosing an interior cavity (112 or 262) which receives an insert (114 or 254) having internal fluid passages defining first and second power nozzles (120, 122 or 280, 282). The power nozzles receive pressurized fluid (130) flowing through the interior cavity of the housing, where the fluid flows into the cavity at the bottom of the housing and flows upwardly to inlets (140, 142) for the power nozzles so that accelerating first and second fluid flows are aimed by the power nozzles toward one another in an interaction region (154 or 284) which exhausts laterally along a spray axis through a horn-shaped throat defined partly within the insert and partly within the flared spray outlet orifice (160 or 290) defined through the sidewall (162) in the housing.

    摘要: An oscillating or pulsing fluid stream, or flow 18, 132, 300, is produced from a flow of pressurized air by fluidic apparatus 10, 100, 130, 180, 220 in a device 250 configured for use in surface cleaning, sweeping, lawn care applications, and the like. Converging inlet chamber walls 20, 22, define a tapered internal lumen having a smooth narrowing profile is configured to generate at a power nozzle 44 a high velocity stream with minimal pressure drop. Downstream of the power nozzle, first and second control ports CP1, CP2 are in fluid communication with the high velocity stream 46 and with each other via an inertance loop 72 having a lumen of selected cross sectional area and length. The varying air flow is directed through an outlet chamber 14, 134 shaped to produce an oscillating flow 18 or a pulsating flow 132.

    摘要: A conformal, cup-shaped fluidic nozzle engineered to generate an oscillating spray is configured as a (e.g., 100, 400, 600 or 700). Preferably, the fluidic circuit's oscillation inducing geometry 710 is molded directly into the cup's interior wall surfaces and the one-piece fluidic cup may then fitted into an actuator (e.g., 340). The fluidic cup (e.g., 100, 400, 600 or 700) conforms to the actuator stem used in typical aerosol sprayers and trigger sprayers and so replaces the prior art “swirl cup” 70 that goes over the actuator stem (e.g., 320), With the fluidic cup (e.g., 100, 400, 600 or 700) and method of the present invention, vendors of liquid products and fluids sold in commercial aerosol sprayers 20 and trigger sprayers 800 can now provide very specifically tailored or customized sprays.

    摘要: A low profile, integrated camera wash nozzle assembly 1010 is readily and unobtrusively integrated into a vehicle's exterior trim surfaces 1420 to make a more visually appealing exterior design while not compromising spray performance. A system and nozzle assembly (e.g., 710, 810, 1010) for cleaning an exterior objective lens or wide-angle sensor's exterior surface 1022 to remove accumulated debris sprays washer fluid at a selected shallow angle which is substantially transverse to the lenses central viewing axis 1050. A low-profile conformal housing fixture 1011 is adapted to receive and aim a very compact fluidic circuit insert 1200 that can generate a wide spray which substantially covers the lens surface, despite being very close to the edge of the lens 1022.
