Abstract:
A fluid ejection chip for a fluid ejection device, the fluid ejection chip comprisinga substrate; and a plurality of nozzle arrangements that are positioned on the substrate, each nozzle arrangement comprising a nozzle chamber defining structure positioned on the substrate to define a nozzle chamber; an active fluid-ejecting structure that is operatively positioned with respect to the nozzle chamber and is displaceable with respect to the substrate to eject fluid from the nozzle chamber; and at least two actuators that are operatively arranged with respect to the active fluid-ejecting structure to displace the active fluid-ejecting structure towards and away from the substrate, the actuators being configured and connected to the active fluid-ejecting structure to impart substantially rectilinear movement to the active fluid-ejecting structure.
