摘要： A fluidic oscillator adapted for use in a showerhead or nozzle assembly includes an eddy filter structure which reduces the adverse effects of fluid supply turbulence on the fluidic oscillator's spraying performance. A nozzle or rain can style showerhead assembly includes a water chamber or manifold which receives water via a central inlet fitting. Water entering the water chamber or manifold flows turbulently into and through the manifold and is expelled under pressure through a plurality of nozzles which are configured as specially adapted fluidic inserts.

摘要： 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.

摘要： A fluidic oscillator suitable for use at colder temperatures for generating an exhaust flow in the form of an oscillating spray of fluid droplets has an inlet for pressurized fluid, a pair of power nozzles configured to accelerate the movement of the pressurized fluid, a fluid pathway that connects and allows for the flow of pressurized fluid between its inlet and the power nozzles, an interaction chamber which is attached to the nozzles and receives the flow from the nozzles, a fluid outlet from which the spray exhausts from the interaction chamber, and a means for increasing the instability of the flow from the power nozzles, with this means being situated in a location chosen from the group consisting of a location within the fluid pathway or proximate the power nozzles. In a first preferred embodiment, the flow instability generating means comprises a protrusion that extends inward from each side of the fluid pathway so as to cause a flow separation region downstream of the protrusions. In a second preferred embodiment, the flow instability generating means comprises a step in the height elevation of the floor of the power nozzles with respect to that of the interaction chamber.

摘要： A fluid spraying or nozzle system adapted for use with cold fluids, viscous fluids or fluids under light pressure includes a fluidic oscillator having a power nozzle and an oscillation chamber coupled to the power nozzle for issuing a jet of fluid into the oscillation chamber and an outlet aperture spraying a jet of fluid into ambient space. The oscillator's walls define an oscillation inducing interaction region causing the jet of fluid to rhythmically sweep back and forth between the sidewalls in the oscillation chamber. The oscillation inducing interaction region defines an outlet throat width which is adapted to work with the power nozzle's width and an a bell-shaped feed that spreads the fluid jet as it leaves the power nozzle, so that the interaction region and feedback channels are quickly filled with fluid at a low pressure and the fluidic oscillator is activated to generate a desired fan pattern of fluid spray.
