ABSTRACT:
A fluidic amplification device having an input, a fluid supply, a fluid sly nozzle for creating a laminar jet of fluid, an output chamber for receiving the laminar jet, control nozzles to control fluid flow through the amplification device from the fluid supply nozzle to the output chamber, wherein the control nozzle acts directly on the fluid to proportionally control the fluid output, vents disposed between the control nozzle and the output chamber, a DC flow output communicating with the output chamber, and pressure signal output ports communicating with the output chamber. By providing outputs for both DC flow and the pressure signal, the DC flow in the pressure signal output channels of the device is reduced and the problems of interstage flow noise, null off-set, parasitic capacitance and inductance in the input and output channels is also reduced.
