Abstract (en)
An apparatus for producing a plurality of streams of liquid droplets comprises a first chamber (1) having an inlet (2). The apparatus also has a second chamber (4) having a plurality of outlets (5). The first chamber also has a channel (10) for conveying liquid from the inlet (2) to an acoustic device (11) for producing vibrations within the liquid. The acoustic device (11) is located within the first chamber (1). The second chamber (4) has a frustoconical internal wall narrowing towards the outlets (5). A generally conical protrusion (9) has a base adjacent the outlets (5) and an apex pointing towards the acoustic device (11). <IMAGE>
