Liquid to be atomized is supplied from a wick to the underside of a vibrating orifice plate which pumps the liquid up through atomizing orifices in the plate and ejects the liquid from is upper side; and liquid which is pumped up through the orifices in an elevated region of the plate, but which has not been ejected, is directed back down through larger openings in a lower region of the plate. The liquid also flows back onto the wick which places the liquid in capillary communication along the underside of the plate with the atomizing orifices for reputing and ejection.
