ABSTRACT:
A full wave fluidic rectifier which produces a direct fluidic output signal having an amplitude which increases from a very low level as the amplitude of an alternating fluidic input signal increases. In includes a nozzle for directing a fluid stream along the rectifier axis into a null venting outlet, two signal outlets which are symmetrically disposed in opposite sides of the null outlet, and two control signal inlets for applying the alternating input signal to the stream, deflecting the stream alternately toward the two signal outlets in proportion to the amplitude of the alternating input signal. The two signal outlets are connected by respective channels of equal fluid resistance to a common channel which serves as the rectifier output.
