US Patent 7874654 Fluid manifold for fluid ejection device

A fluid manifold for a fluid ejection device including a plurality of fluid feed slots includes a first layer and a second layer adjacent the first layer, and a first fluid routing and a second fluid routing 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 of the first fluid routing and the second fluid routing through the first layer is greater than a pitch of the fluid feed slots, and the first fluid routing and the second fluid routing each include a first channel oriented substantially parallel with the fluid feed slots and a second channel oriented substantially perpendicular to the fluid feed slots.
