Abstract: A vehicle windshield defrost system utilizes a fluidic oscillator for sweeping a jet of heated air across the windshield. The fluidic oscillator is of the type having an interaction chamber (20) with sidewalls which converge to a common outlet (21) to form a crossover type output region and thereby reduce the amount of space on the dashboard normally occupied by an output funnel.

Abstract: Air is directed from opposing ends of a trough- like continuous contour which defines a guide path for the two opposing streams. The air streams will be attached to flow along the trough and where the oppositely directed streams impact or inpinge upon each other, they will be deflected normal to their path and the two combined streams will be projected or directed perpendicularly outwardly from the trough in the form of a fan-shaped jet. By controlling the velocity of the two opposing jets, the point of impact or impingement of the two jets can be moved along the trough with the trough defining the path of movement of the point or virtual outlet of outward projection of the combined jets. In preferred embodiments, the defrost and heating and air conditioning outlets for automobiles incorporate the invention so as to avoid protrusions and provide a continuous clean and unbroken appearance.

Abstract: A dual pattern nozzle comprises a fluid oscillator of the type which utilizes an obstacle or island (27) in the path of liquid flow to produce a vortex street downstream of island. A now splitter (28, 29) is disposed downstream of and sufficiently close to the island to prevent the now around the island from re-combining before reaching the flow divider, whereupon liquid vortices are alternately issued from each side of the divider. The spinning liquid breaks up into two patterns of droplets, the patterns being directed at respective spaced areas.

Abstract: A fluidic circuit (200) configured to spray an oscillating pattern of fluid droplets, having an inlet (210) in fluid communication with a source and including a power nozzle (250) with an oscillation chamber having a fluid jet steering section (240) in fluid communication with the power nozzle and having a first fluid pressure accumulating volume opposite (242) a second fluid pressure accumulating volume (244). The fluid jet steering section (240) is in fluid communication with and emits a fluid jet into an oscillation inducing interaction region (260) with opposing first and second side wall features (262, 264) which define an oscillation inducing interaction region in the oscillation chamber for causing the jet of fluid (300) to rhythmically sweep back and forth between the sidewalls in the oscillation chamber.

Abstract: An improved fluidic oscillator, that operates on a pressurized liquid flowing through the oscillator to generate a liquid jet that flows into the surrounding gaseous environment to form of an oscillating spray of liquid droplets, includes: a member into which is fabricated a two-portion, flow channel, with its first portion configured so as to create the flow phenomena in the member that yields the spray's oscillating nature, and its second portion includes a splitter that is used to divide the jet into component sprays whose centerlines assume a specified yaw or pitch angle relative to the centerline of the oscillator.

Abstract: A fluidic oscillator (2) suitable for use at colder temperatures for generating an exhaust flow in the form of an oscillating spray of fluid droplets has an inlet (12) for pressurized fluid, a pair of power nozzles (14) configured to accelerate the movement of the pressurized fluid, a fluid pathway (10) that allows for the flow of pressurized fluid between its inlet (12) and the power nozzles (14), an interaction chamber (18) which is attached to the nozzles (14) and receives the flow from the nozzles, a fluid outlet (20) from which the spray exhausts from the interaction chamber (18), and a means for increasing the instability of the flow from the power nozzles (14). In a first preferred embodiment, said means comprises a protrusion (4) that extends inward from each side of the fluid pathway (10). In a second preferred embodiment, said means comprises a step (24) in the height elevation of the floor of the power nozzles (14) with respect to that of the interaction chamber (18).
