AIR-DISTRIBUTION DEVICE Russian patent published in 2008 - IPC F24F13/06 

FIELD: ventilation equipment, particularly air-distribution means.

SUBSTANCE: air-distribution device comprises connection pipe, jet-splitting central body installed under the connection pipe and attached thereto. The central body is hollow. Central body interior is communicated with control medium source through pipeline. Central axial orifice is created in central body from side facing connection pipe. Deflector linked to central body is installed over the orifice so that gap is created between deflector and central body. Annular fan-like control medium jet impinges upon incoming jet, which results in volumetric incoming jet turbulization and jet attenuation degree increase.

EFFECT: increased jet attenuation degree.
