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 onto the wick which places the liquid in capillary communication along the underside of the plate with the atomizing orifices for repumping and ejection.
Selon l'invention, un liquide à pulvériser est acheminé d'une mèche (32) vers la face inférieure d'une plaque à orifices vibrante (14), laquelle pompe le liquide vers le haut à travers les orifices de pulvérisation (20) ménagées dans la plaque, et l'éjecte de sa face supérieure. Le liquide pompé vers le haut à travers les orifices dans une zone élevée de la plaque, mais qui n'a pas été éjecté, est refoulé vers le bas à travers des orifices plus grands (22) dans une zone inférieure de la plaque. Le liquide reflue également sur la mèche, ce qui lui permet de communiquer par capillarité, le long de la face inférieure de la plaque, avec les orifices de pulvérisation pour repompage et éjection.
