Claim 0:
1. A method of fluid ejection, comprising:
ejecting fluid from a nozzle of a fluid ejector, including flowing the fluid along a first portion of a flow path between a pumping chamber of the fluid ejector and the nozzle; and
refilling the nozzle with fluid from a second portion of the flow path between a return channel and the nozzle,
wherein flow of fluid along the second portion of the flow path causes deflection of a membrane formed across and in the interior of the second portion of the flow path, and wherein the deflection of the membrane provides the second portion of the flow path with a first impedance when fluid is being ejected from the nozzle and a second impedance when fluid is not being ejected from the nozzle, and wherein the first impedance is greater than the second impedance.
