Abstract
Liquid is finely atomized and is ejected through apertures in a disc by virtue of high frequency vibration of the disc at controlled amplitudes. To insure an adequate supply of liquid to the disc while avoiding overflow and droplet leakage through the apertures, an injector meters supply liquid to the disc and simultaneously extracts excess liquid from the disc with a siphon action.
