Abstract

Atomiseur vibrant destiné à pulvériser un liquide le liquide Cet appareil comprend un ajutage qui éjecte le liquide pulvérisé et un corps qu'un dispositif fait vibrer et auquel est assujetti un tube qui y amène le liquide à pulvériser. La longueur de ce tube est égale à un multiple de la demi-longueur d'onde correspondant à la vitesse du son dans ce tube, de sorte que l'énergie qui rayonne dans ce dernier est renvoyée en phase vers l'arrière dans le corps de l'appareil en service. Application notamment à la pulvérisation d'un combustible liquide dans un moteur ou dans une chaudière à échangeur de chaleur.
