Title (EN) STACKED DROP GENERATORS FOR PULSED INK JET PRINTING
(FR) GENERATEURS DE GOUTTES EMPILES D"IMPRESSION A JET D"ENCRE PULSE
Abstract: front page image
(EN)A stacked drop generator apparatus (20) for ink jet printing includes a stackable housing (22) of electrically nonconductive material having a cavity (24) containing fluid. A pressure wave is produced in the fluid by a device (26) which is deformed in response to electrical pulses. Each cavity (24) is flooded with fluid and has a nozzle (40) integral with the housing. The nozzle has an intake end (41) in the fluid cavity, an exit port (42) through which fluid is expelled from the housing. The cavity of the housing adjacent the nozzle has a tapered shape to concentrate the effect of the pressure wave on the fluid.
(FR)Un appareil a generateurs de gouttes empiles (20) pour l"impression par jet comprend un logement empilable (22) d"un materiau electriquement non conducteur ayant une cavite (24) contenant un fluide. Une onde de pression est produite dans le fluide par un dispositif (26) qui est deforme en reponse a des impulsions electriques. Chaque cavite (24) est inondee de fluide et possede un ajutage (40) solidaire du logement. L"ajutage possede une extremite d"admission (41) dans la cavite du fluide, un orifice de sortie (42) au travers duquel le fluide est expulse de l"enceinte. La cavite de l"enceinte adjacente a l"ajutage possede une forme conique pour concentrer l"effet de l"onde de pression sur le fluide.
