Abstract

La présente invention concerne la génération de goutte­ lettes à la demande. The present invention relates to the generation of gout lettes on request.

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. The device according to the invention comprises at least one nozzle 16 supplied with liquid by a conduit connected to a tank and associated with a pressure transducer 9 engen drant pulsations on the liquid; the transducer pressure has an internal cavity of very small volume 17 with an inlet and an outlet for the liquid, which is directly in contact with the wall of the material of the pressure transducer, said inlet being connected to the reser see liquid and said outlet supplying the nozzle.

Application aux imprimantes à projection d'encre. Application to ink jet printers.
