(54) Fluidic oscillator with bistable jet-type amplifier


(57) Subject of this invention is a new version of fluidic oscillators with a bistable amplifier (10) of jet-type, used in particular for control of fluid flow on the surface of a body exposed to fluid floe, where in place of the so far known feedback channels the oscillation generation is based on employing propagation and reflection of compression and expansion waves in a resonance channel (1) connected to the control nozzle (11) of the jet-type bistable amplifier (10).
