Title (EN) FLUID EJECTION DEVICE
(FR) DISPOSITIF D'ÉJECTION DE FLUIDE
Abstract: front page image
(EN) A fluid ejection device includes a fluid ejection chamber having a drop ejecting element therein, a first fluid channel to communicate a first fluid with the fluid ejection chamber, a second fluid channel to communicate a second fluid different than the first fluid with the fluid ejection chamber, and a fluid pump communicated with one of the first fluid channel and the second fluid channel. As such, the fluid ejection chamber is to selectively eject drops of the first fluid, the second fluid, and a combination of the first fluid and the second fluid therefrom.
(FR) L'invention concerne un dispositif d'éjection de fluide comprenant une chambre d'éjection de fluide pourvue d'un élément d'éjection de gouttes, un premier canal de fluide pour transmettre un premier fluide dans la chambre d'éjection de fluide, un second canal de fluide pour transmettre un second fluide différent du premier fluide dans la chambre d'éjection de fluide, et une pompe à fluide en communication avec le premier canal de fluide ou le second canal de fluide. Ainsi, la chambre d'éjection de fluide est conçue pour éjecter sélectivement des gouttes du premier fluide, du second fluide, et une combinaison du premier fluide et du second fluide.
