METHOD TO GENERATE OSCILLATIONS OF LIQUID FLOW AND HYDRODYNAMIC GENERATOR OF OSCILLATIONS FOR ITS REALISATION Russian patent published in 2014 - IPC F15B21/12 B06B1/18 

FIELD: machine building.

SUBSTANCE: liquid from a discharge manifold (5) is divided into two flows - main and additional ones. The value of flow rate in the main flow is maintained as more or equal to the value of the flow rate of the additional flow. The main flow is swirled with the help of swirling channels (3) in a flow chamber (2) with an outlet nozzle (4). A part of the main flow is released via a nozzle (4), and the other part is sent to an axial channel (8) made in the central body (7). The outlet (10) of the channel (8) is closed with an elastic partition (11). From the discharge manifold (5) via a distribution channel (13) the liquid is sent into an additional manifold (12). The manifold (12) is connected with a nozzle (4) via a gap (6) and with a channel (8) via a partition (11), with the help of which they provide for separation and elastic interaction of flows from the manifold (12) and the channel (8). As a result of which in the additional flow at first pressure growth is delayed, and then additional pulse action is provided due to forces of elasticity, with the help of which the main swirled flow in the chamber (2) is damaged, and short-term, pulse increase of liquid flow via the nozzle (4) is ensured.

EFFECT: invention makes it possible to expand functional and operational capabilities of an oscillation generator.
