The discharge end of fluidic oscillator 14 is mounted in hole 24 of oscillator mounting section 20.
To control the operation of fluidic feedback oscillator 14 and thus enable the transmission of information by the system a hydraulically operated feedback valve is placed in each of the feedback passages 92 and 94.
For example, it will be recognized that fluidic feedback oscillator 14 would have the same effect if it were designed to have little or no hysteresis and the valves in feedback passages 92 and 94 were designed to fully close.
