METHOD AND DEVICE FOR GENERATING OSCILLATION OF FLUID FLOW Russian patent published in 2007 - IPC F15B21/12 B06B1/18 

FIELD: mechanical engineering.

SUBSTANCE: method comprises swirling fluid under pressure and generating at least two oppositely rotating vortices. The swirled fluid flows are separated by the nozzle of the centrifugal nozzle. One of the flows is directed to the space with controlled flexibility, and the other one is connected with the outlet nozzle. The hydrodynamic generator has housing with vortex chamber, swirling passages, outlet nozzle, pressure pipeline connected with swirling passages, and central body mounted in the vortex chamber with a spaced relation to the side and space of controlled flexibility. The space is connected with the intermediate nozzle of the centrifugal nozzle provided with swirling passages of opposite directions through the passages of the outlet nozzle and connected with the space of controlled flexibility.

EFFECT: expanded functional capabilities.
