An outlet opening formed in the downstream end wall and axially aligned with the power nozzle and has a width and depth such that internal pressure in the oscillation chamber is greater than ambient. The outlet wall 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.

摘要： A fluidic oscillator capable of generating free fluid jets having distinctive, controllable and industrially/commercially useful flow patterns has a switching chamber having an inlet port that allows a pressurized fluid to enter and flow through the oscillator, an exhaust passage having a sidewall that forms one boundary wall of the switching chamber, a container passage having a sidewall that forms the second boundary wall of the switching chamber, a compliance member connected to the distal end of the container passage, and an expansion chamber connected to the distal end of the exhaust passage, with the expansion chamber having an exhaust orifice that allows fluid to flow from the oscillator. In operation, such an oscillator yields a contained fluid jet that issues from the inlet port into the swishing chamber and alternately switches its flow direction between the container and exhaust passages. This switching action serves to generate controllable pressure waves in the exhaust passage and expansion chamber which act to control the pattern of the free fluid jet that flows from the orifice.

摘要： Air is detected 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 impinge 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.

摘要： There is disclosed an oscillating reed particularly for use in generating a sweeping or oscillating air flow pattern which is rendered clickless by limiting directions of bending of the reed element to an axis transverse to the direction of air flow. This significantly silences the oscillations and, in conjunction with polishing of the edges of the reed and rounding the corners of the mounting bar in which the downstream end of the reed is secured, cracking and breakage of the reed element has been substantially eliminated thereby lengthening significantly the life of the oscillating element.
摘要翻译：公开了一种特别用于产生扫掠或振荡空气流动模式的振荡簧片，其通过将簧片元件的弯曲方向限制在横向于空气流动方向的轴线上而使其无缝化。这显着地使振荡沉默，并且结合对簧片边缘的抛光以及使固定杆的下游端固定的安装杆的角部四舍五入，基本上消除了簧片元件的破裂和断裂，从而显着地延长了振荡元件的寿命。

摘要： A dual pattern nozzle comprises a fluid oscillator of the type which utilizes an obstacle or island in the path of liquid flow to produce a vortex street downstream of the island. A flow splitter is disposed downstream of and sufficiently close to the island to prevent the flow 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.

摘要： A leak detection system and method for fluid operated device includes a backloaded fluidic oscillator having an interaction chamber, a power nozzle at its upstream end coupled to a source of fluid under pressure and an exit throat at its downstream end. The interaction chamber first diverges from the power nozzle and then converges towards the exit throat. A pair of outlet passages are connected to the exit throat; one of the outlet passages is connected to the fluid operated device and the other of the outlet passages is connected to a fixed volume and a vent whereby the backloaded fluidic oscillator oscillates at a rate which is a function of the leakage of the fluid operated device.

摘要： 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.
