FLUIDIC OSCILLATOR AND DISPLAY FOUNTAIN
First Claim
1. A fluidic device having an input and at least two alternative outputs, wherein flow to at least a first of said outputs is to a pressure accumulator resulting in increasing pressure in said first output until a first high pressure threshold is reached at which point the device switches flow to a second of said outputs, the flow therefrom including said supply flow and at least a proportion of said original flow into said accumulator and until a second low pressure threshold is reached in said first output, whereupon the cycle is repeated, and employing flow from said second output in a system.

Abstract
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.
