FLUID EJECTION DEVICE Russian patent published in 2016 - IPC B41J2/175 

FIELD: machine building.

SUBSTANCE: disclosed liquid ejection device capable of supplying liquid stably and continuously through feeding liquid tube, which is subjected to consecutive deformation in accordance with movement of carriages with liquid-ejecting head, with simultaneous achievement of compactness of main housing of device. Fluid ejection device includes ejection fluid head to eject liquid in target; carriage to perform reciprocating movement in shell of main housing with liquid-ejecting head, and transitional device capable of supplying ink in ejection fluid head; and fluid feeding tube, which is subjected to consecutive deformation in shell of main housing in accordance with reciprocating movement of carriage in drawing back and forth for ink supply from tank for ink on upper side, located outside zone of movement carriage adapter on downstream side. At that, adapter is installed so that connecting part with supply liquid tube is separated from end part of carriage, which is side, opposite to side, on which there is fluid tank, in direction of movement of the carriage.

EFFECT: feed of fluid stably and continuously.
