<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> |
