KSS-TYPE NOZZLE Russian patent published in 2015 - IPC B05B1/34 

FIELD: process engineering.

SUBSTANCE: invention relates to sprayers. Claimed nozzle comprises the casing, union and swirling insert aligned therewith and having the outer helical knurling and inside diverging conical opening. Axially symmetric opening communicated with diffuser is made in the union. Nozzle is arranged at the casing lower part a axial symmetry. The nozzle is provided with two-step diffuser aligned with said swirling insert. Note here that the diffuser first step makes the extension of said diverging conical bore inside the swirling insert and is made of wear-proof material. Diffuser second step makes the extension of its first step. Note also that helical knurling is made on its inner conical surface. Said conical surface with helical knurling of the diffuser second step is perforated.

EFFECT: higher quality of spraying and efficiency.
