A nozzle arrangement for an inkjet printhead, the nozzle arrangement includes a substrate defining a nozzle chamber bounded by walls and a roof, the roof defining an ink ejection port; an ink-ejecting member positioned in the nozzle chamber, the ink-ejecting member displaceable towards the ink ejection port to eject ink from the ink ejection port; a work-transmitting structure displaceable with respect to the substrate, the work-transmitting structure connected to the ink-ejecting member; an actuator connected to the work-transmitting structure, the actuator for displacing the work transmitting structure upon receipt of an electrical drive signal; and a covering formation defining an air chamber. The actuator is positioned within the air chamber. The roof, the work transmitting structure and the covering formation together defining a protective structure for the nozzle arrangement.
