Abstract
An ultrasonic fluid spraying device including an electroacoustic converter; optionally at least one coupling rod element; a spraying device provided as a radial collar projecting outwards from an axial element with which it is integral, and tuned to the frequency of the converter; and devices for supplying the fluid to the immediate vicinity of an operative area of the spraying device.
Claims25
A device for the ultrasonic spraying of at least one liquid, comprising:
- an electroacoustic converter delivering an axial vibration of given wavelength,
- at least one coupling rod element,
- a radial sprayer constructed in the shape of a radial collar having a side surface which projects outwards with respect to the coupling rod element with which it is integral and which is constructed at a node of a half-wavelength of the axial vibration, said sprayer being tuned to the wavelength of the vibration of said converter, and
- means for introducing said at least one liquid to be sprayed into the immediate vicinity of said side surface of the sprayer, said entire side surface vibrating with a substantially uniform amplitude thereby providing spraying with a compressed spectrum.

A device for the ultrasonic spraying of at least one liquid, comprising:
- an electroacoustic converter delivering an axial vibration of given wavelength,
- at least one coupling rod element,
- a radial sprayer constructed in the shape of a radial collar having a side surface which projects outwards with respect to the coupling rod element with which it is integral, said coupling rod element having a tip, said radial sprayer being constructed axially spaced from said tip at a node of a half-wavelength of the axial vibration, said sprayer being tuned to the wavelength of the vibration of the converter, and
- means for introducing said at least one liquid to be sprayed into the immediate vicinity of said side surface of the sprayer, said side surface being cylindrical and having an axis parallel to an axis of the axial vibration, all of said side surface vibrating with a substantially uniform amplitude thereby providing spraying with a compressed spectrum.
