Abstract (en)

[origin: WO9621512A1] A spray nozzle mountable on the outlet (3) of a fluid dispensing device for dividing a fluid into fine droplets. The nozzle includes a core (11) and an atomiser (2) together defining a vortex chamber (14, 24) communicating with the outside via a spray port (21) in said atomiser (2), and a number of vortex channels (15, 16) opening non-radially into the vortex chamber (14, 24). The atomiser (2) has an oblong shape with a longitudinal major axis lying in a horizontal plane. Said vortex channels (15, 16) preferably communicate with the outlet (3) of the spray device via two symmetrical feed ducts (12, 13) extending on either side of the core (11) and lying in a horizontal plane.
