METHOD OF OSCILLATIONS GENERATION OF LIQUID FLOW AND GENERATOR OF FLOW OSCILLATIONS Russian patent published in 2015 - IPC F15B21/12 B06B1/20 

FIELD: machine building.

SUBSTANCE: under method of oscillations generation of the liquid flow the liquid from main line (6) is divided to flows, supplied to swirling channels (4) and (5), and is swirled in vortex chamber (2) in opposite directions. At that near channels (4) and (5) in sections plane of the chamber (2) the pressure at axis of liquid rotation is minimum, and in zone of active mixing of the opposite swirled flows it is maximum. The swirled flow from channels (4) having high tangential component of speed is discharged with minimum flowrate through output nozzle (3). Pressure in chamber (2) abruptly rises and acts on the partition (11). As result of resilient interaction with volume of medium filled elastic cavity via the partition (11), reverse pressure pulse reduces intensity of rotation of the opposite swirled flows. Tangential speed reduces, opposite swirled flows stop, and liquid flowrate through nozzle (3) abruptly increases.

EFFECT: increased power of oscillations generation due to reduced hydraulic losses and increased weight of interacting flows, and reduced dimensions, simplified design and extension of application conditions.
