Abstract
A nozzle device for an inkjet printer includes a support structure defining an ink inlet chamber connected to a source of ink; an elongate actuating arm cantilevered relative to the support structure; and a nozzle chamber structure defining a nozzle chamber for receiving ink from the ink inlet chamber, the nozzle chamber structure comprising a static portion extending from the support structure, and further comprising a movable wall portion mounted to the actuating arm between the ends of the elongate actuating arm. The elongate actuating arm terminates in a free end within the nozzle chamber, the free end adapted to move within the nozzle chamber to eject ink therefrom. The elongate actuating arm is positioned to divide the nozzle chamber from the ink inlet chamber.
