Ultrasonic spray nozzle and method

Abstract From the Canadian patent

Michael Soth and, James R. Klemm, Abstract Of The Disclosure An ultrasonic spray nozzle includes a, piezoelectric transducer which develops mechanical vibrations in response to an applied periodic electrical potential. The vibrations are mechanically amplified and propagate to an atomizing surface over which fluid to be atomized is discharged by an internal fluid passage. Maximum vibrational amplitude of the atomizing surface is achieved when the frequency of the applied electrical potential equals the natural resonant frequency of the nozzle. A parameter of the applied electrical potential such as, fequency, is periodically varied such that the vibrational amplitude of the atomizing …
