Abstract : A fluidic pulsing device is disclosed which comprises at least one fluid amplifier and several vortex valve restrictors. One or more amplifiers direct fluid flow to the several vortex valves, which are arranged in parallel fashion. Such an arrangement allows for optimization of design geometries, and therefore, optimization of performance, despite the fact that the physical dimensions of the apparatus may be severely restricted.
