Abstract: A fluidic oscillator which is free of feedback passages has an oscillation chamber having a length greater than its width, a pair of mutually facing and complementary-shaped sidewalls (13, 14), planar top and bottom walls (141, 142), and first and second end walls (15). An input power nozzle (17) is formed in said first end wall (15) having a width W and a depth D, for issuing a stream of fluid into the oscillation chamber, and forms alternately pulsating, cavitation-free vortices in said oscillation chamber on each side of the stream. An interconnect passage or channel (107) proximate the downstream end wall (103) enlarges the sweep angle and improves periodicity of the oscillations. The outlet wall (148) is hingedly connected to a chamber wall and the chamber is such that it can be molded with the outlet wall hingedly connected thereto in one molding and forms one side of the inteconnect passage or channel.

Abstract: A gas burner comprising a gas manifold feeding an array of fluidic oscillators (49). Each fluidic oscillator has a power nozzle (42) connected to the gas manifold and an outlet for issuing a sweeping jet of gas to ambient. Each fluidic oscillator is spaced a predetermined distance from its neighboring fluidic oscillators and a baffle plate (30) controls air flow to the sweeping jet of gas from each fluidic oscillator.

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 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: Procédé et appareil de maximisation du transfert d'énergie thermique vers ou à partir d'un jet d'air oscillant ou balayé (10) propagé sur un pare-brise (21). Le jet d'air ambiant est projeté sur de courtes distances à partir d'un ajutage (11) correctement orienté vers ledit pare-brise. On fait en sorte que la longueur d'onde lambda du jet oscillant ou balayé soit supérieure à la distance de l'ajutage à partir du pare-brise et inférieure à la longueur du pare-brise dans le sens de la propagation du jet d'air sur ce dernier, de manière qu'il y ait moins de perte ou un gain d'énergie thermique à partir dudit jet d'air dans l'espace situé entre ledit ajutage et ledit pare-brise, ainsi qu'un transfert maximum d'énergie thermique entre le pare-brise et le jet d'air par réduction de l'épaisseur de n'importe quelle couche limite isolante.
