Abstract: Ameliorations aux deflecteurs d'oscillations utilises en particulier pour generer une configuration d'un ecoulement d'air de balayage ou d'oscillations. Les deflecteurs d'oscillations de cette invention sont constitues par une pluralite de baguettes elastiques espacees entre elles (12-1, 12-2 et 12-3) qui, de preference, sont fabriquees avec des fibres de graphite liees ensemble par une matrice de resine epoxyde renforcee par un canevas leger de fibre de verre. Pour reduire au minimum l'effet de torsion et/ou les forces qui peuvent deformer les baguettes et par consequent creer du bruit, une pluralite d'ondulations (30) sont formees dans la bande de graphite Ainsi, le deflecteur d'oscillations (10) selon la presente invention offre les quatre principaux avantages suivants: (1) reduction du bruit du a la deformation, (2) modulation de l'amplitude, cad insensibilite de l'amplitude d'oscillation dans des plages etendues de debits, (3) debut facilite de l'oscillation, et (4) resistance a la fatigue amelioree.

Abstract: A fluid flow control element is constituted by a fluidic amplifier having an interaction region shaped to provide side walls leading to a pair of fluid flow outlets. The fluid flow inlet for the fluidic amplifier has positioned adjacent thereto at least one control fluid passageway, and the flow of fluid to the outlet passages is controlled by at least one pivoted valve or flap element pivoted between two positions for controlling flow fluid from the fluid inlet to a selected one of a pair of fluid flow passageways or outlets. In the preferred embodiment the fluid flow inlet and outlet and the interaction chamber are such that the fluid pressure in the chamber is always above any pressure in the load passageways and fluid from the fluid flow inlet flows out from the chamber through the control passage. The pivoted valve or flap element, in the preferred embodiment is flat so that it is balanced relative to gravity as well as aerodynamically, so that it will not change position due to back pressures as when outlet passages or receivers are partially or completely blocked and does not cause any torque on the valve element about said pivot and hence will remain in the control position despite severe back loading. The invention is described in relation to a low pressure system, such as automobile air flow systems wherein a number of the unique aspects of the invention are utilized.

Abstract: Un systeme de vaporisation en eventail d'un liquide pour devier cycliquement un jet de liquide entre des positions extremes definies par une paire de parois extremes (31, 32) peut fonctionner par temps froid par expansion du jet de liquide. Dans le mode de realisation, prefere une paroi limite (40) de l'oscillateur fait un angle d'environ 5o avec l'ajutage (21) sur la gorge de sortie (30), et la sortie ou gorge possede sensiblement la meme section pour une oscillation donnee en fermant les extremites laterales de la gorge de sortie. Ceci permet le fonctionnement par temps froid lorsque le liquide possede une tension superficielle et une viscosite plus grandes tout en conservant essentiellement le meme angle de dispersion du jet devie cycliquement. Le dispositif est particulierement utile pour les systemes de lavage de pare-brise d'automobiles par tous les temps.

Abstract: A full coverage fluidic oscillator (2) includes a fluidic circuit member preferably having an oscillation inducing internal chamber, at least one inlet (8) or source of fluid under pressure, at least a pair of output nozzles (14, 16) connected to the source of fluid for projecting at least first and second impinging fluid jets into free space, where the first and second impinging jets collide or impinge upon one another at a selected jet angle to generate a substantially omni-directional sheet jet having selected thickness. The first and second jets are aimed at a pre-selected intersection point in free space where impingement is to occur. The sheet jet's thickness Δy is determined by the time-varying path or oscillation of each of the first and second impinging jets. The first and second impinging jets can be made to oscillate or pulsate by use of vortex generating amplifier structures (68, 70, 72, 149) within the internal chamber's fluid flow paths.
