Abstract: An alignable conformal, cup-shaped flag-mushroom fluidic nozzle assembly is engineered to generate a flat fan or sheet oscillating spray of viscous fluid product 316. The nozzle assembly includes a cylindrical flag mushroom fluidic cup member 180 having a substantially closed distal end wall with a centrally located snout defined therein. The flag mushroom cup assembly effectively splits the operating features of the fluidic circuit between a lower or proximal portion formed in the housing's sealing post member and an upper, or distal portion formed in cup member 180 which, in cooperation with the sealing post's distal surface, defines an interaction chamber 192 fed by impinging jets each comprising a continuous distribution of streamlines that impinge at selected angles to define arcs providing a lesser degree of impingement at a centered axial plane within the exit orifice 194 and a greater degree of impingement at the edges of exit orifice 194.

Abstract: Spray nozzle assembly (300) is configured to generate a swirled spray (312) with improved rotating velocity w 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).

Abstract: 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.

Abstract: An external lens washing system has an aiming fixture configured to support and constrain an external lens which is exposed to the elements and apt to become soiled with debris. A nozzle assembly is configured to be supported and aimed toward the external lens by the aiming fixture and has at least one laterally offset washing nozzle projecting from the aiming fixture to a spray washing fluid toward the external lens surface, spraying at a shallow, glancing spray aiming angle to impinge upon and wash the lens external surface. Optionally, an integrated image sensor and lens washing assembly is configured for use with a remote control method for cleaning an exterior objective lens surface and includes a sealed image sensor housing assembly including an integral, remotely controllable lens cleaning system with an optimized configuration for aiming one or more cleansing sprays from one or more laterally offset fluidic oscillators.
