<p>A fluid ejection device includes a fluid manifold, a substrate coupled to the fluid manifold, and a fluid distribution structure disposed between the fluid manifold and the substrate. The fluid manifold includes a fluid supply chamber and a fluid return chamber. The substrate defines a flow path including a flow path inlet for receiving fluid, a nozzle for ejecting fluid droplets, and a flow path outlet for channeling away un-ejected fluid. The fluid distribution structure includes a fluid supply channel including a supply inlet fluidically coupled to the fluid supply chamber and a supply outlet fluidically coupled to the flow path. The fluid distribution structure also includes a fluid bypass channel including a bypass inlet fluidically coupled to the fluid supply chamber, a bypass outlet fluidically coupled to the fluid return chamber, and a flow inhibitor between the bypass inlet and the bypass outlet providing a supplemental flow resistance to the fluid bypass channel. The flow inhibitor includes a convergent-divergent throat section.</p> |
