Abstract
La présente invention concerne la génération de goutte
lettes à la demande.
Le dispositif selon l'invention comporte au moins une
buse 16 alimeniée en liquide par un conduit relié à un
réservoir et associé à un transducteur de pression 9 engen
drant des pulsations sur le liquide; le transducteur de
pression présente une cavité interne de volume très petit 17
avec une entrée et une sortie pour le liquide, lequel se trouve
directement en contact avec la paroi du matériau du
tranducteur de pression, ladite entrée étant reliée au réser
voir de liquide et ladite sortie alimentant la buse.
Application aux imprimantes à projection d'encre.
