Claim 0:
1. Spray nozzle of the type comprising a body (1), which has a fluid inlet region and a fluid outlet orifice, the body (1) housing:
a core (2), internally defining a passage, of increasing cross-section, in communication with the outside substantially at the point of the core's smallest cross-section, resulting in a Venturi effect, said smallest cross-section starting adjacent the fluid inlet region,
an insert (3), provided with an outlet slot (31) forming the fluid outlet orifice (16) of the nozzle and defining the opening angle thereof,, the core (2) and the insert (3) being at a distance from one another and forming between them a working chamber (23) in the body (1),, wherein the nozzle further comprises an additional part (7) called a splitter, housed in the working chamber (23), arranged to form an obstacle to a flow of a fluid, said splitter comprising two axial through-orifices (71, 72), each forming a fluid passage, on either side of a radial plane (73), and, at the outlet, a substantially flat blade (75), in the central plane such that the two streams passing through the two axial through-orifices (71, 72) of the splitter, flow along the substantially flat blade and follow a surface thereof before combining and then impinging the surface of the outlet slot (31) of the insert, ultimately generating a flat jet.
