ROTARY NOZZLE FOR THE HIGH PRESSURE WASHING UNIT Russian patent published in 2018 - IPC B05B3/04 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to the high pressure washing unit rotary nozzle. Application describes rotary nozzle (10) for the high-pressure washing unit comprising housing (12) having at least one tangentially passing into it inlet (18) and located in the housing (12) end wall (24) outlet (22). At the outlet (22) a cup-shaped recess (30) is located having through hole at the center. Nozzle also comprises located in the housing (12) and having through passage (72) nozzle slider (62), which is by the ball-shaped end (64) rests against the cup-shaped recess (30). Recess (30) longitudinal axis (70) is obliquely passing relative to the housing (12) longitudinal axis (26). Moving through the housing (12) spherical end is driven by the liquid into the rotary motion, at which it rests against the supporting surface (40). Downstream the supporting surface (40) after the nozzle on the housing (12) wall, along the liquid flow several hydraulic resisting elements are arranged, each of which has reflective surface (52; 120). Immediately before each reflecting surface (52; 120), guide surface (54; 122) is located in the direction of fluid movement, to which the reflective surface (52; 120) is smoothly adjacent. Guide surface (54; 122) is oriented obliquely to the radial plane, in which the housing (12) longitudinal axis (26; 124) is located.

EFFECT: enabling the possibility of the nozzle slider (62) speed effective limitation without significant reduction of its spinning.
