Abstract
An orifice plate is vibrated up and down at high frequency while liquid is delivered to its lower surface so that the liquid is ejected up from the plate in the form of very small diameter droplets. The upper surface of the plate is constructed to resist wetting and buildup of a liquid film thereby to form smaller diameter liquid droplets which are ejected to greater heights. The upper surface of the plate may be treated with a surfactant such as a flurosurfactant.
