Title (EN) FLUID EJECTION DEVICE WITH CIRCULATION PUMP
(FR) DISPOSITIF D'ÉJECTION DE FLUIDE COMPRENANT UNE POMPE DE CIRCULATION
Abstract: front page image
(EN)A fluid ejection device includes a fluid recirculation channel, and a drop generator disposed within the channel. A fluid slot is in fluid communication with each end of the channel, and a piezoelectric fluid actuator is located asymmetrically within the recirculation channel to cause fluid flow from the fluid slot, through the recirculation channel and drop generator, and back to the fluid slot.
(FR)La présente invention se rapporte à un dispositif d'éjection de fluide qui comprend un canal de recirculation de fluide et un générateur de gouttes disposé à l'intérieur du canal. Une fente d'alimentation en fluide est en communication fluidique avec chaque extrémité du canal, et un actionneur de fluide piézoélectrique est placé de façon asymétrique à l'intérieur du canal de recirculation pour amener le fluide à s'écouler depuis la fente d'alimentation en fluide, à passer à travers le canal de recirculation et le générateur de gouttes et à revenir vers la fente d'alimentation en fluide.
