Spray nozzle

Liquid passes from annular orifice 45 on to surface 47. High pressure air from passage 414 and orifice 410 forms the liquid into a film and drives it towards acute-angled edge 47A. Under the influence of this air, and also further high pressure air from orifice 417, the liquid leaver the edge 47A as a spray. The two air currents meet just downstream of the edge and set up high frequency oscillations, thus further breaking up the droplets of liquid. In other embodiments, more than one flow of liquid may be used, for example, one on each of two surfaces which meet to form an acute angle.
