摘要： A fluidic oscillator having independent frequency and amplitude control includes a fluidic-oscillator main flow channel having a main flow inlet, a main flow outlet, and first and second control ports disposed at opposing sides thereof. A fluidic-oscillator controller has an inlet and outlet. A volume defined by the main flow channel is greater than the volume defined by the controller. A flow diverter coupled to the outlet of the controller defines a first fluid flow path from the controller's outlet to the first control port and defines a second fluid flow path from the controller's outlet to the second control port.

摘要： A device for vibrating tubing as it is inserted into a wellbore is disclosed. The device has a fluidic switch that has no moving parts. The fluidic switch is connected to a piston that oscillates back and forth in a cylinder. The piston is the only moving part. As the piston oscillates, it blocks and unblocks openings in the cylinder or other components. The movement of the piston controls the timing of the oscillation, and also generates an impulse or vibration. The vibration may reduce the friction between the tubing and the wellbore.

摘要： A fluidic device (10) has an input (8) and at least two alternative outputs (1,2), wherein flow to at least a first of said outputs is to a pressure accumulator (12,30) resulting in increasing pressure in said first output until a first high pressure threshold is reached. The device then switches flow to a second of said outputs, the flow therefrom including said supply flow and at least a proportion of said original flow. This pertains until a second low pressure threshold is reached in said first output, whereupon the cycle is repeated. Flow from at least said second output is employed in a system, such as a display fountain.

摘要： A fountain (50) comprises a supply of water under pressure, a primary fluidic diverter (10) having an input (12) for said supply, and first and second outputs (16a, b) diverging from said input. Two control ports (20a, b) are provided with control flow to direct input flow to one or other of the two outputs that lead to the two inputs of a vortex amplifier (40). This comprises a vortex chamber (54), a radial port (50), a vortex inducing port (60) and an axial output port (58). One (16a) of the diverter outputs is connected to the vortex inducing port, the other (16b) to the radial port, so that supply to said axial output port is modulated by formation of a vortex in the chamber when flow is to the vortex inducing port. The axial port leads to a nozzle whereby a vortex spray or axial jet is produced, depending on which diverter output (16a, b) is active. A wind detector (100) has a vertical jet (102) and a catcher (104) which fails to catch water from the jet in high wind conditions. The catcher feeds the control port (20a) of a diverter 101, or such other pressure or flow detector as may be convenient. A fountain array of elements may comprise a number of diverters, the outputs of which have branches supplying the control ports of others in the array, whereby internal control is provided.

The one or more water nozzles each comprises a housing having an inlet for receiving a flow of water under pressure, a fluidic oscillator having an oscillation chamber and at least one power nozzle coupled to the inlet and the oscillation chamber for projecting at least one jet of water into the oscillation chamber in one or more outlets from said oscillation chamber for issuing one or more pulsating jets of water into the spa tub below the waterline. An air passage in the outlet entrains ambient air in water passing through the outlet. The fluidic oscillator is a low frequency reversing chamber oscillator wherein the oscillation chamber has a reversing wall. The power nozzle is centrally located for issuing a jet of water toward the reversing wall, and a pair of liquid passages leads from the reversing chamber on each side of the power nozzle, respectively, for alternating carrying periodic pulses of water and wherein the outlet passages are smoothly extended to intersect at a common outlet to ambient and water from the passages merge to form a low-frequency swept jet of water, and the passages are dimensioned and angulated relative to each other to control a fan angle of liquid jet which is periodically swept into said common outlet to ambient water in said tub.
