Abstract: A modular nozzle assembly for use with standard trigger sprayers 1, 300 has components which replace the standard nozzle cap 24, 320. A user selectable and user changeable fluidic plate or fluidic circuit member 152, 372 is configured to allow the user to configure a particular combination of components to create precise 2-D or 3-D spray pattern when spraying or dispensing a liquid product from a trigger sprayer or aerosol sprayer. A spray kit with a user configurable modular nozzle assembly and a method for configuring a trigger or aerosol sprayer for a selected spray pattern includes a reconfigurable nozzle assembly with a replacement nozzle cap 150, 346 having modular fluidic circuit insert element retaining features 170, 172 or 376 and at least one detachable modular fluidic circuit insert element 152, 372 which a user may attach to the fluidic modular element retaining nozzle cap 150, 346.

Abstract: A spray dispenser is configured to generate a swirled output spray pattern 152 with improved rotating or angular velocity ? 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.

Abstract: A unitary or one-piece integral image sensor and washing nozzle assembly or module 100, 300, 400 is configured to enclose, protect, and aim multiple image sensors and effectively clean multiple lenses (e.g., 102, 104) simultaneously while using only one nozzle head (e.g., 120, 320 or 420) with at least one optimized spray pattern (e.g., 122). The module includes a housing with a cover or bezel (e.g., 106) that supports and orients the lenses and the nozzle head aims spray at the lenses along a spray axis, with the relative heights and spacings of the nozzle's outlet orifice (e.g., 174) and the surfaces of the lenses (e.g., 102, 104) selected so that a particular spray either glances across and washes a nearest lens (e.g., 102) or impacts and washes over a farthest lens (e.g., 104).

Abstract: An inexpensive, durable and efficient irrigation nozzle assembly is adapted to generate a specialized rectangular spray in a 3-jet fluidic circuit which generates a substantially planar rectangular spray from a confluence of three jets. The 3-jet geometry circuit has selected floor & taper features configured to create a customizable rectangular or triangular spray pattern. Depending on the throw desired, the nozzle assembly of the present invention can be configured with a second fluidic circuit to generate a flat fan to obtain various aspect ratios in a rectangular spray.
