FLUIDIC SELF-EXCITED OSCILLATOR Russian patent published in 1998 - IPC

FIELD: automation and computer engineering. SUBSTANCE: fluidic self-excited oscillator includes jet-type discrete element containing working chamber bounded by two side walls, two control nozzles, two receiving channels, divider with concave deflector, two drain channels and two feedback channels connecting the receiving channels with control nozzles. Each side wall of working chamber is provided with shoulder at distance of d≥(1-1,5)B from deflector edges along axis of self-excited oscillator in way of supply nozzle having width of b≥(0,5-1)B, where B is width of deflector. EFFECT: enhanced reliability. 2 dwg
