SPRAYER Russian patent published in 2014 - IPC B05B1/34 

FIELD: process engineering.

SUBSTANCE: invention relates to sprayers. Proposed nozzle comprises case, union and swirler aligned with both. Axially symmetric opening communicated with diffuser Case bottom part accommodates axially symmetric nozzle with confuser and outlet cylindrical orifice. Note here that diffuser and confuser are coaxially connected with the case cylindrical chamber. Said chamber accommodates cylindrical swirler with outer helical rifles. Swirler inside has diverging conical channel to feed fluid from cylindrical orifice made in union. Note here that said swirler is fixed at case bottom by spacer with at least three helical through grooves made at sleeve cylindrical shell. Note also that said spacer is arranged between swirler bottom edge and confuser top edge to make cylindrical mixing chamber aligned with the case.

EFFECT: higher quality of spraying and efficiency.
