<p>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.</p> |
