Реферат: A method for ejecting fluid from a fluid ejector includes actuating a piezoelectric actuator to cause deformation of a membrane defining a wall at a first end of an elongated channel of the fluid ejector, the deformation of the membrane causing ejection of a droplet of fluid from a nozzle disposed at a second end of the channel. The elongated channel fluidically connects a first channel to the nozzle, the first channel disposed at the first end of the elongated channel, and wherein an impedance of the first channel is at least ten times greater than an impedance of the elongated channel. Deformation of the membrane induces fluid flow along the elongated channel, and wherein at least 60% of the fluid flow induced by the deformation of the membrane is in a direction extending from the first end of the elongated channel to the second end of the elongated channel.
