<p>According to the invention, the swirl chamber (7) in a liquid spray nozzle communicates with the outside by means of a coaxial outlet hole (10) and communicates with a coaxial circular channel (11) by means of numerous oblique first transfer channels (12-15). Each first transfer channel (14) is delimited by an external face (21) having a generally rectilinear profile which connects tangentially to the peripheral wall (8) of the swirl chamber (7), while the internal face is provided with a concave profile (L1) over most of the length thereof. In this way, the fineness of the droplets sprayed from the nozzle is improved, particularly when the liquid has a viscosity greater than that of water.</p> |
