Abstract:
An apparatus for ultrasonically self-cleaning an orifice, the apparatus comprising:a die housing defining:a chamber having a first cross-sectional area adapted to receive a pressurized liquid;an inlet adapted to supply the chamber with the pressurized liquid; anda die tip, the walls of the die tip defining at least one vestibular portion having a second cross-sectional area smaller than the first cross-sectional area terminating in at least one exit orifice having a third still smaller cross-sectional area, the vestibular portion adapted to receive the pressurized liquid from the chamber and pass the liquid to the exit orifice and out of the die housing; anda means for applying ultrasonic energy to a portion of the pressurized liquid without applying ultrasonic energy to the die tip, wherein the means for applying ultrasonic energy is affixed at a nodal point to the die housing and is further located within the chamber and terminates in close proximity to the vestibular portion and the exit orifice is adapted to be self-cleaning when the means for applying ultrasonic energy is excited with ultrasonic energy while the exit orifice receives pressurized liquid from the chamber and passes the liquid out of the die housing.
