An apparatus for controllably focusing ultrasonic acoustical energy to a desired position within a liquid stream by manipulation of the shape of a wave generator used to propagate acoustic energy as well as by the selection of the shape of a chamber within which the acoustic energy is applied to the liquid. When the ultrasonic acoustical wave generator is excited, it applies ultrasonic energy to the pressurized liquid contained within the chamber as the liquid passes through the housing without mechanically vibrating the exit orifice. |
