ANNULAR JET OSCILLATOR Russian patent published in 2024 - IPC F15C1/22 F04F5/00 G01P5/14 

FIELD: machine building.

SUBSTANCE: invention relates to automation and is proposed for use in measuring speed parameters and control in systems subjected to radiation effects and operating in explosive conditions, as well as in aircraft instruments of aircraft. Technical result is achieved by the fact that the jet annular self-contained oscillator consists of three jet amplifiers, in series in the layers connected by signals into a ring, wherein the third amplifier in the third layer is made on an enlarged scale from 1.2 to 2.5:1 to the other two, made with the same geometry of the flow part of the chamber, wherein its output feedback channels are of shorter length with the input of the third amplifier directly above the output of the second amplifier and the output of the third amplifier above the input of the first amplifier.

EFFECT: shortened feedback lines of the jet ring self-contained oscillator to expand the frequency range of measurement.
