An ultrasonic apparatus and method for increasing the flow rate of a pressurized liquid through an orifice by applying ultrasonic energy to a portion of the pressurized liquid. The apparatus includes a die housing which defines a chamber adapted to receive a pressurized liquid and a means for applying ultrasonic energy to a portion of the pressurized liquid. The die housing further includes an inlet adapted to supply the chamber with the pressurized liquid, and an exit orifice defined by the walls of a die tip. The exit orifice is adapted to receive the pressurized liquid from the chamber and pass the liquid out of the die housing. When the means for applying ultrasonic energy is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip. The method involves supplying a pressurized liquid to the foregoing apparatus, applying ultrasonic energy to the pressurized liquid but not the die tip while the exit orifice receives pressurized liquid from the chamber, and passing the pressurized liquid out of the exit orifice in the die tip.

[ What is claimed is:] [1.] An apparatus for increasing the flow rate of pressurized liquid through an orifice, the apparatus comprising:a die housing defining:a chamber adapted to receive a pressurized liquid;an inlet in communication with said chamber and adapted to supply the chamber with the pressurized liquid; andan exit orifice in communication with said chamber and defined by the walls of a die tip, the exit orifice being adapted to receive the pressurized liquid from the chamber and pass the liquid out of the die housing; anda means for applying ultrasonic energy to a portion of the pressurized liquid within the chamber without applying ultrasonic energy to the die tip, wherein the means for applying ultrasonic energy is located within the chamber, wherein the flow rate of the pressurized liquid is at least about 25 percent greater than the flow rate of an identical pressurized liquid out of an identical die housing through an identical exit orifice in the absence of excitation by ultrasonic energy.
