FLUID FLOW SWIRLER Russian patent published in 2015 - IPC F15D1/04 

FIELD: machine building.

SUBSTANCE: swirler contains cylindrical casing, inside it concentrically three blades of triangular shape are installed. The blades are secured along larger leg on the rod located on casing axis, and are secured in the base. The base is made in form of the ring with jumpers. The base is installed at the casing output. On the rod the fairing with ribs is secured, and casing at the fairing side is made cone. The side surface of cone and fairing ribs are parallel. Between the fairing and base the cone spiral is installed concentrically with axis. Each blade along the large leg at the small leg is bent along radius and is secured on the base jumper bent along the same radius. Bends of blades and inclinations of the spiral turns to the axis are directed to opposite sides.

EFFECT: increased efficiency of agitation of the fluid flow, upon decreasing of the hydraulic resistance and increased balance of flow speeds along the pipeline cross-section.
