    • A fluid manifold (120) for a fluid ejection device (130) including a plurality of fluid feed slots (132) includes a first layer (140) and a second layer (150) adjacent the first layer, and a first fluid routing (160) and a second fluid routing (170) each provided through the first layer and the second layer. The fluid ejection device is supported by the second layer, and the first fluid routing is communicated with one of the fluid feed slots, and the second fluid routing is communicated with an adjacent one of the fluid feed slots. A pitch (D3) of the first fluid routing and the second fluid routing through the first layer is greater than a pitch (D1) of the fluid feed slots, and the first fluid routing and the second fluid routing each include a first channel (162/172) oriented substantially parallel with the fluid feed slots and a second channel (166/176) oriented substantially perpendicular to the fluid feed slots.
    • 用于包括多个流体供给槽(132)的流体喷射装置(130)的流体歧管(120)包括邻近第一层的第一层(140)和第二层(150),以及第一流体路线(160 )和每个通过第一层和第二层提供的第二流体路线(170)。 流体喷射装置由第二层支撑,并且第一流体路线与流体供给槽中的一个连通,并且第二流体路线与相邻的一个流体供给槽连通。 第一流体路线的间距(D3)和穿过第一层的第二流体路线大于流体供给槽的间距(D1),并且第一流体路线和第二流体路径各自包括第一通道(162) / 172)基本上平行于流体供给槽和基本上垂直于流体供给槽定向的第二通道(166/176)。
