Summary: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 theshape 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. Cette invention concerne un dispositif permettant de focaliser une énergie acoustique ultrasonique sur un point donné au sein d'un courant liquide, ceci en manipulant la forme d'un générateur d'ondes pour propager l'énergie acoustique et en sélectionnant la forme d'une chambre dans laquelle l'énergie acoustique est appliquée à un liquide. Lorsqu'il est excité, le générateur d'onde applique une énergie ultrasonique sur le liquide sous pression contenu dans la chambre lorsqu'il traverse le boîtier, sans soumettre l'orifice de sortie à des vibrations mécaniques.
