Abstract: A miniature low-flow, fluid conserving washer nozzle has an elongated housing enclosing an interior volume aligned along an inlet axis which receives an elongated insert member with internal fluid passages defining first and second power nozzles, so that accelerating first and second fluid flows are aimed by the first and second power nozzles toward one another in an interaction region defined within the insert with an insert throat to aim spray laterally or transversely along a spray axis through an aligned sidewall aperture in the nozzle housing. The nozzle may generate a planar oscillating sweeping fan of spray, produced by fluidic oscillations at low flow rates, typically 150-300 ml/min at 25 psi. The fan of spray generated may be varied from 20° to 70° or about 15°-60°. The outer dimensions of spray head could be as small as 3.5 mm. The fluidic geometry is also capable of spraying high viscosity liquids up to 25 CP or up to 15 CP.

Abstract: Provided is a continuous nozzle assembly that includes a fluidic geometry that extends between an inlet and an outlet, wherein a flow of fluid is configured to enter the inlet and process through the fluidic geometry and exit the outlet in a predetermined spray pattern. The continuous nozzle assembly may be made by additive manufacturing methods. In one embodiment, provided is a fluidic oscillator insert that includes a fluidic geometry that is manufactured by additive manufacturing techniques.

Abstract: 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.
