Device for rotating a fluid inside a spray nozzle, assembly comprising such a device and coating device

A spraying nozzle, intended for spraying a product, defines a passage for the circulation of the product through the nozzle, wherein the passage opens through a wide connection orifice to the outside of the nozzle at an upstream end thereof, and through a narrow spraying orifice at a downstream end of the nozzle in order to spray the product; the passage has, between the connection orifice and the spraying orifice, at least one pre-atomization narrowing capable of atomizing the product, followed by a broadening downstream of the pre-atomization narrowing.
