SHORT-JET DEFLECTOR NOZZLE Russian patent published in 2021 - IPC B05B1/18 A01G25/09 

FIELD: irrigation devices.

SUBSTANCE: nozzle contains a case including a lower part with an external thread for screwing it into the pipe of the water supply belt of the sprinkler machine, a longitudinal passage channel with a diameter of d₁=4…8 mm and a length of l₁=(3…4)·d₁, radial holes with a diameter of d₂=0.2·d₁, made at a distance of l₂=(0.5…1.0)·d₁ from the sharp edge of the inlet hole of the longitudinal passage channel, and the upper part with a deflector made in concert with the case. The case is made in the form of a polyhedron, and the deflector is made in the form of a curved surface with radius R₁=10·d₁, width b₂=(3…5)·d1 and depth h₂=3.5…5.0 mm, it is located at an angle α=40…60° relatively to the flat area. The case and the deflector are made by casting as a single part. At the end of the longitudinal passage channel, an internal thread is made, into which a replaceable nozzle is screwed, and the difference in its diameters is determined by the ratio 7/12. On the deflector, there is a vertical divider of the flow part, made in the form of a wedge, the sharp part of which is directed towards the flow and has an angle of 15…17°. The angle between the sides of the wedge and the deflector plane is 90°, the heights of the sides of the wedge are equal, they form a surface parallel to the longitudinal passage channel, and its height corresponds to the center of the circumference of the longitudinal passage channel.

EFFECT: invention provides improved manufacturability, increased spray evenness, the range of raindrops and the area of rain capture.
