Abstract: A vehicle nozzle system having a source of washer liquid (14) under pressure, a fluidic oscillator (11) comprising a housing and a fluidic insert having a power nozzle, an oscillation chamber (oc) having an upstream end (pn) coupled to the power nozzle for issuing a jet of washer liquid into the oscillation chamber and a downstream end having an outlet aperture (oc'') for issuing a jet of wash liquid to ambient, and side and top and bottom walls, an oscillation inducing silhouette in the oscillation chamber for causing said jet of wash liquid to rhythmically sweep back and forth between the sidewalls in the oscillation chamber. Top and bottom walls of the oscillation chamber first diverge for a predetermined distance in a downstream direction and then convert towards each other through said outlet aperture. This enables the deflection angle to be adjusted for different vehicles and applications by changes to the fluidic insert without changes to the housing.

Abstract: A reversing chamber (IC) oscillator has an oscillation chamber (IC) with a reversing wall (RW), a centrally located power nozzle (PN) for issuing a jet of liquid toward the reversing wall (RW), and a pair of liquid passages (CH1, CH2) from the reversing chamber (IC) on each side of the power nozzle (PN), respectively, for alternately issuing periodic pulses of liquid. The outlet passages (CH1, CH2) are smoothly extended to intersect at a common outlet (CO) to ambient and are dimensioned and angulated relative to each other to control the fan angle of a liquid jet which is periodically swept in the common outlet (CO) and sprayed to ambient. The pair of fluid passages (CH1, CH2) have an upstream end at the reversing chamber (IC) and a downstream end at the common outlet (CO) and each passage (CH1, CH2) has an outer wall which, with the reversing wall (RW), define an oval.

Abstract: A two-stage liquid spray device having an outlet region with an island (41) and an exit aperture (47) and a fluidic oscillator (33) driving said outlet region. The improvement for the spray device is operable at a low pressure to achieve full-area coverage with substantially uniform droplets and wherein all of the spray droplets land on the desired work surface and do not bounce. The fluidic oscillator includes an oscillation chamber (33), a power nozzle (31) for introducing a jet of liquid from a source into the oscillation chamber. The oscillation chamber is configured to produce a pair of alternating control vortices which substantially preclude wall attachment of said jet traversing said oscillation chamber, thus avoiding a heavy endedness in the oscillatory jet. An outlet from the oscillation chamber to the outlet region, whereby the jet rhythmically sweeps in end pulses to each side of the island and forms a sheet at the exit aperture. The sheet is rhythmically waved or swept in the ambient air to form the uniform droplets. A transverse slot defines the lateral boundary of the sweeping sheet.

Abstract: A fluid oscillator for issuing a sweeping jet of air has a continuous inertance loop which has a section passing through the power nozzle of the fluidic oscillator. The continuous inertance loop is essentially coplanar with the plane of the fluidic oscillator so the basic oscillator element can be two identical molded parts which snap fit together.

Abstract: An air distribution system, particularly for automobiles, in which the depth of the unit is relatively short and in which control over the direction of air flow can be achieved by movement of an element in a plane orthogonal to the direction of air flow. A main air flow outlet is formed in a wall member and a parallel flow path is formed adjacent the outlet and has diverging walls which are relatively short so that there is no wall attachment or coanda effects per se. Flow of fluid through the adjacent parallel flow path or passageway exits through an opening that directs the air in a direction generally parallel to the short wall direction of the adjacent flow path. By controlling the entry of air into the parallel flow path, the main air flow vector is deflected and the direction of flow is thereby controlled. The deflection is greater when an obstacle slightly intrudes the side of the outlet opposite the parallel flow path. With a rectangular outlet opening, four adjacent parallel paths with short, straight or curved walls and adjacent parallel passages and obstacle intruders, the flow can be controlled in four directions or can be caused to diffuse generally in a forward direction. The element for control is basically a plate element movable in the plane transverse to the direction of the main air flow so that relatively short depth is required for installation of the device in an automobile system. By adding a control flap, the angular sweep can be greatly enlarged. By adding fixed control louvers, the maximum angles of directivity can be increased. The control plate can be positioned by a solenoid or driven by a motor to cause oscillatory sweep of the air issuing into the ambient.

Abstract: In an automobile air flow system, air is forced through an air outlet element or nozzle (13, 21, 24) in a sweeping air stream pattern by an oscillating reed or vane member (42) supported solely at the downstream end (43) for air initiated oscillatory movement in the flow path of the air from the source; a weight (41) is on the free, upstream end of the vane and is of a size such that the rate of oscillation is determined by the spring constant of a spring in the vane member and the weight. The oscillating vane (42) is proportioned with respect to the cross-sectional size of the outlet such that at any extreme of its oscillatory movement it does not physically contact any other structural member.

Abstract: A conformal, cup-shaped fluidic nozzle engineered to generate an oscillating spray is configured as a (e.g., 100, 400, 600 or 700). Preferably, the fluidic circuit's oscillation inducing geometry 710 is molded directly into the cup's interior wall surfaces and the one-piece fluidic cup may then fitted into an actuator (e.g., 340). The fluidic cup (e.g., 100, 400, 600 or 700) conforms to the actuator stem used in typical aerosol sprayers and trigger sprayers and so replaces the prior art “swirl cup” 70 that goes over the actuator stem (e.g., 320), With the fluidic cup (e.g., 100, 400, 600 or 700) and method of the present invention, vendors of liquid products and fluids sold in commercial aerosol sprayers 20 and trigger sprayers 800 can now provide very specifically tailored or customized sprays.
