Abstract (en)
[origin: US2021268522A1] The spray nozzle includes a body, which has a fluid inlet region and a fluid outlet orifice, and which houses:a core, internally defining a passage, of increasing cross-section, in communication with the outside substantially at the point of its smallest cross-section, resulting in a Venturi effect,an insert, provided with an outlet slot defining the opening angle of the nozzle, the core and the insert being at a distance from one another and forming therebetween a working chamber.The nozzle further includes a splitter, housed in the working chamber, arranged to form an obstacle to the flow of the fluid, the splitter having two axial orifices, each forming a fluid passage, on either side of a radial plane, such that the two streams passing through the orifices of the splitter combine and then impinge the surface of the outlet slot of the insert, ultimately generating a flat jet.
