Abstract: A fluidic oscillator adapted for use in a showerhead or nozzle assembly includes an eddy filter structure which reduces the adverse effects of fluid supply turbulence on the fluidic oscillator's spraying performance. A nozzle or rain can style showerhead assembly includes a water chamber or manifold which receives water via a central inlet fitting. Water entering the water chamber or manifold flows turbulently into and through the manifold and is expelled under pressure through a plurality of nozzles which are configured as specially adapted fluidic inserts.

Abstract: Provided is a PCV valve assembly that includes a fluidic geometry that allows for the flow of combustion fluid/gas to flow between an inlet and an outlet and switch between two modes of operation, (i) a radial or high flow mode, and (ii) a tangential or low flow mode, as dictated during the operation of the engine. At low vacuums, the fluidic equipped PCV valve assembly has been tuned to operate in the radial mode producing high flow rates due to low flow resistance. As vacuum increases, the PCV valve assembly is tuned to automatically switch modes. This may be enabled due to the shape of the fluidic geometry and the bypass channel which is adapted to vary the amount of flow between a first and a second control ports. The bypass channel allows the geometric fluidic pattern to switch between the high flow mode and the low flow mode.

Abstract: 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.

IPC: B05B1/08
Abstract: 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.

Abstract: A fluidic circuit configured to spray an oscillating pattern of fluid droplets, having an inlet in fluid communication with a source and including a power nozzle with an oscillation chamber having a fluid jet steering section in fluid communication with the power nozzle and having either (a) a first fluid pressure accumulating volume opposite a second fluid pressure accumulating volume or (b) a first fluid jet attachment feature opposing a second fluid jet attachment feature. The fluid jet steering section is in fluid communication with and emits a fluid jet into an oscillation inducing interaction region with opposing first and second side wall ears or features which define an oscillation inducing interaction region in the oscillation chamber for causing the jet of fluid to rhythmically sweep back and forth between the sidewalls in the oscillation chamber and create a distally projecting oscillating spray.
