FLUID FLAY JET NOZZLE WITH CONTROLLED DROP SIZE WITH INVARIABLE OR VARIABLE STRAY ANGLE Russian patent published in 2014 - IPC B05B1/04 

FIELD: process engineering.

SUBSTANCE: invention relates to fluid sprayers and can be used for irrigation, fire fighting, dyes spraying and production of artificial ice. Proposed nozzle comprises lower plate with bottom pusher surface. Besides, it comprises at least one fluid inlet at inner end of said pusher surface and inlet lower edge of outlet located along lower pusher surface outer end. Besides, it comprises upper plate with upper pusher surface and outlet to edge arranged along upper pusher surface outer end. It includes squeezable seal to seal nozzle lower plate with nozzle upper plate. Note here that pusher upper and lower surface are opposed to make fluid channel between said surfaces. Said fluid channel can direct fluid at pressure from at least one inlet to slotted outlet. The latter is formed between opposite outlet upper and lower edges. Besides, this nozzle comprises fluid drop size adjustment mechanism to be attached to said upper and lower plates to adjust drops of fluid forced from slotted outlet by selective contraction of squeezable seal. Besides, this nozzle can comprise multiple separate fluid inlets and separate chambers.

EFFECT: controlled fluid flow rate, drop size, stray angle and shape.
