Abstract (en)
In order to generate the droplets, the liquid E is passed to the nozzles (1), a pressure wave being able to reach all the nozzles and being such that the pressure wave surface (11) forms a substantial angle alpha with the line of nozzles. Thus the pressure wave passes successively through each nozzle at different times, creating the successive formation of the drops. The invention applies to ink jet printers. <IMAGE>
Abstract (fr)
Pour engendrer les gouttelettes on envoie dans le liquide E vers les buses (1), une onde de pression pouvant atteindre l'ensemble des buses et telle que la surface d'onde de pression (11) fasse un angle notable α avec la ligne de buses. Ainsi l'onde de pression passe successivement par chaque buse à des instants différents provoquant la formation successive des gouttes. L'invention s'applique aux imprimantes à jet d'encre.
