More Information
Summary:A nozzle assembly that produces a cone-shaped spray pattern of entrained liquid droplets is disclosed. The nozzle includes an ultrasonic atomizer for atomizing a liquid on an atomizing surface located at the end of an atomizing stem. The nozzle assembly is supplied pressurized air that is directed to the atomizing surface by intercommunicating ports, chambers and/or channels. To provide the cone-shaped spray pattern, the ports, chambers and/or channels cause or direct the pressurized gas to rotate about the atomizing stem. When the rotating pressurized gas exits the nozzle assembly via proximate the atomizing surface, atomized liquid droplets become entrained in the gas. The rotating pressurized gas propels the droplets forward and moves at least some droplets circumferentially outward in the cone-shaped spray pattern. In various embodiments, the pressure of the gas can be adjusted to control the size and shape of the cone-shaped pattern and the distribution of droplets.
