Abstract (en)
[origin: CA3023570A1] A spraying nozzle (34) for spraying a product, the nozzle (34) defining a passage (60) for the circulation of the product through the nozzle (34), wherein the passage (60) opens through a wide connection orifice (62) to the outside at an upstream end (56) of the nozzle (34) and through a narrow spraying orifice (64) at a downstream end (58) of the nozzle (34) in order to spray the product. The passage (60) has, between the connection orifice (62) and the spraying orifice (64), at least one pre-atomization narrowing (66) capable of atomizing the product, followed by a broadening (68) downstream of the pre-atomization narrowing (66).
