METHOD AND APPARATUS FOR MAINTAINING CONTROL OF LIQUID FLOW IN A VIBRATORY ATOMIZING DEVICE

摘要

Liquid to be atomized is supplied from a wick (32) to the underside of a vibrating orifice plate (14) which pumps the liquid up through atomizing orifices (20) in the plate and ejects the liquid from its 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 (22) in a lower region of the plate. The liquid also flows back ont o the wick which places the liquid in capillary communication along the underside of the plate with the atomizing orifices for repumping and ejectio n.
