20160030954 | Owl, Double-bowl and slot-bump fluidic oscillator circuits, improved fluidic nozzle assemblies and methods for generating sprays with enhanced cold performance - 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. | 02-04-2016 |
20150183404 | ADAPTIVE, MULTI-MODE WASHER SYSTEM AND CONTROL METHOD - A vehicle speed, ambient temperature or surface-condition responsive wash system | 07-02-2015 |
20140299672 | Method and Fluidic Apparatus for Generating Pulsed and Oscillating Air Flow for Surface Cleaning and Sweeping - An oscillating or pulsing fluid stream, or flow, is produced from a flow of pressurized air by fluidic apparatus in a device configured for use in surface cleaning, sweeping, lawn care applications, and the like. A converging nozzle assembly defining a tapered internal lumen having a smooth narrowing profile is configured to generate at a power nozzle a high velocity stream with minimal pressure drop. Downstream of the power nozzle, first and second control ports are in fluid communication with the high velocity stream and with each other via an inertance loop having a lumen of selected cross sectional area and length. The varying air flow is directed through an outlet chamber shaped to produce an oscillating or a pulsating flow. | 10-09-2014 |
20140291423 | Cup-shaped Nozzle Assembly with Integral Filter Structure - A filtering nozzle assembly or spray head has a conformal nozzle component engineered to generate a filtered spray and configured as a small cylindrical member having a substantially open proximal end and a substantially closed distal end wall with a centrally located discharge orifice defined therein. Optionally, cup-shaped filtered orifice defining member also includes a fluidic circuit's oscillation inducing geometry molded into the cup or directly into the distal surface of a sealing post and the one-piece filter cup provides the fluidic circuit's discharge orifice. | 10-02-2014 |
20140263742 | Cup-shaped Fluidic Circuit with Alignment Tabs, Nozzle Assembly and Method - An automatically alignable conformal, cup-shaped fluidic nozzle engineered to generate an oscillating spray is configured as a cylindrical cup having a substantially open proximal end and a substantially closed distal end wall with a centrally located power nozzle defined therein and between first and second distally projecting alignment tabs or wall segments. Optionally, the fluidic circuit's oscillation inducing geometry is molded directly into the sealing post's distal surface and a one-piece cup provides the discharge orifice. | 09-18-2014 |
20130045095 | WASHER PUMP - An improved automotive pump assembly includes a volute pumping chamber configured to operably contain a rotatable impeller which, when driven, draws fluid into a fluid inlet and pumps the fluid to and through a fluid outlet. The volute chamber has an exterior sidewall with a constant internal first radius over a first sidewall portion and transitions to a second sidewall portion of increasing radius. The chamber's second sidewall portion defines a first end at a sidewall transition point tangent to the constant radius sidewall segment to define a second end which is tangent to the volute chamber's fluid outlet with a second radius that is greater than the first radius. | 02-21-2013 |
