Patent ID: 8672463

Claim:
A fluid ejection device, comprising: a fluid manifold comprising a fluid supply chamber and a fluid return chamber; a substrate coupled to the fluid manifold, the substrate defining a flow path comprising a flow path inlet for receiving fluid, a nozzle for ejecting fluid droplets, and a flow path outlet for channeling away un-ejected fluid; and a fluid distribution structure disposed between the fluid manifold and the substrate, the fluid distribution structure comprising: a fluid supply channel comprising a supply inlet fluidically coupled to the fluid supply chamber and a supply outlet fluidically coupled to the flow path; and a fluid bypass channel comprising 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 comprising a convergent-divergent throat section.
