Fluid spray apparatus

A method of providing a fluid spray at a flow rate in the range of approximately 1.2-1.9 gpm that yields massaging, tactile sensations, as the droplets of said spray impact upon the skin of one in the line of flight of said spray, which are comparable to those produced by non-fluidic generated sprays operating in the range of approximately 2.0-2.5 gpm, said method comprising the steps of:

• using a fluidic oscillator to generate said spray,
• wherein said fluidic oscillator configured so as to provide a spray which exhibits an oscillation frequency in the range of 10-60 cps.

• using a fluidic oscillator to generate said spray,
• wherein said fluidic oscillator configured so as to provide a spray which exhibits an oscillation frequency in the range of 10-60 cps.

A method of providing a fluid spray at a specified flow rate that feels, as the droplets of said spray impact upon the skin of a bather in the line of flight of said spray, to a bather using said spray that said spray is being delivered at a higher flow rate than said specified flow rate at which said spray is being operated, said method comprising the steps of:

• using a fluidic oscillator to generate said spray,
• wherein said fluidic oscillator configured so as to provide a spray which exhibits an oscillation frequency of greater than 60 cps.

A method of providing a multi-functional spray head, said method comprising the steps of:

• stacking a plurality of fluidic oscillators one on top of the other, each oscillator having a body member with top, bottom, side, front and rear outer surfaces, each oscillator having a fluidic circuit embedded in said top surface, said circuit forming a path in which a fluid may flow through said oscillator, each said fluidic circuit having a fluid inlet, a power nozzle, an interaction chamber and an outlet having a prescribed fan angle in said front surface from which a fluid may exit said oscillator,
• configuring said body members of said oscillator stack such that the flow of fluid from adjoining oscillators in said stack have a specified angle of divergence between the centerlines of the planes defined by the flows from the outlets of said adjoining oscillators,
• surrounding said stack of fluidic oscillators with a plurality of orifices that emit fluid sprays formed by other than the use of fluidic oscillators.
