Fluid ejection device including recirculation system

摘要

A fluid ejection device including, at least, one recirculation system is disclosed. Such recirculation system contains, at least, one drop generator, recirculation channels that include an inlet channel, an outlet channel and a connection channel and a fluid feedhole that communicates with the drop generator via the inlet channel and the outlet channel of the recirculation channel. The recirculation channels can be asymmetrical with reference to the drop generator.

1. A fluid ejection device comprising at least one recirculation system, said recirculation system comprising:
a drop generator; a recirculation channel including an inlet channel to direct fluid in a first direction, an outlet channel to direct fluid in a second direction opposite the first direction, and a connection channel between the inlet channel and the outlet channel; and a fluid feedhole that communicates with the drop generator via the inlet channel and the outlet channel, wherein the recirculation channel is asymmetrical with reference to the drop generator such that a length of the inlet channel between the drop generator and the fluid feedhole is different than a length of the outlet channel between the drop generator and the fluid feedhole.
