Patent ID: 6927786

Claim:
A nozzle arrangement for an inkjet printhead, the nozzle arrangement including: (a) a nozzle chamber for holding ink; (b) a dynamic structure having: a lever arm; and an operative portion in fluid communication with the nozzle chamber, the dynamic structure being mounted for rotational movement about a pivot axis with respect to the nozzle chamber upon actuation; (c) a fluid ejection port in fluid communication with the nozzle chamber for allowing ejection of ink upon movement of the dynamic structure relative to the nozzle chamber during actuation; (d) an actuator extending between the lever arm and an anchor point, and having a predetermined length in a quiescent state prior to actuation; the nozzle arrangement being configured such that, upon actuation, the length of the actuator changes such that the actuator applies a force between the lever arm and the anchor to cause rotational movement of the dynamic structure, which in turn causes ejection of the ink from the fluid ejection port.
