Patent ID: 7896478

Claim:
A fluid path unit for a fluid ejection device, comprising: first pressure chambers arrayed in a first pressure chamber row; second pressure chambers arrayed in a second pressure chamber row adjacent to the first pressure chamber row; first outlet paths, through which the first pressure chambers respectively communicate with first nozzles, the first outlet paths arrayed in a first outlet path row; second outlet paths, through which the second pressure chambers respectively communicate with second nozzles, the second outlet paths arrayed in a second outlet path row; a common fluid reservoir; first connection paths, though which the first pressure chambers communicate with the common fluid reservoir; and second connection paths, through which the second pressure chambers communicate with the common fluid reservoir, wherein the second pressure chambers overlap with the common fluid reservoir as viewed in a direction in which the second pressure chambers are deformable; wherein each of the first connection paths extends across the second outlet path row; and wherein the first pressure chambers do not overlap with the common fluid reservoir as viewed in a direction in which the first pressure chambers are deformable.
