    Abstract: A fluidic flow meter comprising a fluidic oscillator having an oscillation chamber, a power nozzle for issuing a jet of fluid into the oscillation chamber, an outlet for issuing fluid from the oscillation chamber. A bendable fiber optic wave guide loop has a section adapted to lose light, as a result of flexing or bending, is mounted in a flow path in the oscillation chamber and subjected to oscillatory flow of the fluid. Light is injected into one end of the fiber optic wave guide and a detector senses the oscillatory loss of light in the fiber optic wave guide as a measure of fluid flow through the fluidic oscillator.

    Abstract: Fluidic transducers of electrical signals from an electronic computer to accurately switch flow of a liquid to a utilization device. A liquid filled hollow channel (166 and 166') is accelerated along the flow axis thereof to produce a fluid control signal for a bistable fluidic switch element (112) with a cross-over type interaction channel (42) and a common outlet (45) to a pair of output passageways (147 and 148). In a preferred embodiment, electrical signals from an electronic computer (220) are supplied to a coil (170) centered by a spring (190 and 191) in a magnetic field, first in one direction of current flow and then in the opposite direction, to introduce bidirectional movement of the coil (170) and the hollow channel means (166 and 166') coupled thereto. The signals are preferably frequency modulated (205) (but may be pulse width modulated).

    Abstract: 17 vide partiel produit dans le passage d'admission d'une chambre à tourbillon est utilisé pour déplacer le liquide d'un compartiment à un autre afin de maintenir le niveau de liquide dans au moins l'un des compartiments en deçà d'un niveau prédéterminé du liquide dans l'autre compartiment. Dans un mode de réalisation, l'unité de tourbillon (14) ou un autre organe d'aspiration développe un vide partiel à la hauteur maximale d'un tube de syphon (8) s'étendant entre les deux chambres, le vide aspirant le fluide des deux ou au moins de l'une des deux chambres vers le sommet du tube (8) amorçant ainsi l'effet de syphon. Une pompe de mines (6) possédant une pression négative insuffisante pour faire monter le liquide à la hauteur maximale du tube de syphon (8) est utilisée pour amener le liquide à une charge et, de concert avec l'unité de tourbillon (14), pour établir le vide partiel requis par l'amorçage de l'effet de syphon. L'unité de tourbillon (50) peut également être logée dans le tube de syphon (52, 54) et peut être utilisée comme pompe pour amener le liquide d'un compartiment seulement à un autre ou, dans un autre mode de réalisation, comme syphon pour déplacer le liquide dans les deux directions pour maintenir les niveaux du liquide dans les deux récipients à une différence de hauteur prédéterminée l'un par rapport à l'autre.

    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 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.
