A droplet generator for a continuous stream ink jet print head comprising: an elongate cavity (13) for containing the ink; nozzle orifices (15) in a wall of said cavity for passing ink from the cavity to form jets, said nozzle orifices extending along the length of said cavity; and actuator means for vibrating the ink in said cavity such that each said jet breaks up into ink droplets at the same predetermined distance from said wall of the cavity, said actuator means being disposed on the opposite side of said cavity to said wall and comprising vibration means which is divided up along the length of said cavity at least partially into at least two parts, characterised in that said actuator means further comprises a backing member (21) disposed further from said cavity than said vibration means and secured to and bridging said parts into which said vibration means is at least partially divided, said vibration means being interposed in line between said backing member and said cavity.

La présente invention concerne un générateur de gouttelettes pour tête d'impression à jet d'encre continu comprenant: une cavité allongée (13) contenant l'encre; des nez de buse (15) placés dans une paroi de cette cavité pour projeter l'encre contenue dans la cavité sous forme de jets, lesquels nez de buse s'étendent sur la longueur de la cavité; et un moyen d'actionnement permettant de faire vibrer l'encre dans la cavité de manière que chaque jet se divise en gouttelettes d'encre à une même distance prédéterminée de la paroi de la cavité. Le moyen d'actionnement est placé du côté de ladite cavité qui est opposé à ladite paroi, il comprend un système de vibration divisé au moins partiellement dans le sens de la longueur de la cavité en au moins deux parties, et il se caractérise en ce qu'il comprend en outre un élément de renfort (21) placé plus loin de la cavité que le moyen de vibration, lequel élément de renfort est attaché aux parties et relie entre elles les parties qui composent le moyen de vibration au moins partiellement divisé, ledit moyen de vibration étant placé longitudinalement entre l'élément de renfort et la cavité.
