FIELD: machine building.
SUBSTANCE: invention relates to fluid medium spraying devices (spraying nozzles) and, especially, to nozzles, used for water flow acceleration. Spraying nozzle for fluid medium comprises elongated housing with inlet end and outlet end and forms passing in it channel, wherein channel includes inlet channel and outlet channel having outlet diameter, which is smaller, than inlet diameter. Channel also forms tapered channel, passing from inlet channel to outlet channel with plurality of blades or grooves, arranged along conical channel circumference to increase flow rate, wherein reducing outlet flow turbulence and deviation.
EFFECT: invention provides high flow rates, reducing flow turbulence and deviation.
