ABSTRACT:
A nozzle device is provided for an inkjet printer. The nozzle device includes a support structure defining an ink inlet chamber connected to a source of ink. An elongate actuating arm is cantilevered relative to the support structure. A nozzle chamber structure defines a nozzle chamber for receiving ink from the ink inlet chamber. The nozzle chamber structure includes a static portion extending from the support structure and defines a nozzle opening through which ink in the nozzle chamber can be ejected. The nozzle chamber structure further includes a movable wall portion mounted to the actuating arm, between its ends, so that the actuating arm terminates in a free end within the nozzle chamber. Upon actuation of the actuating arm, the free end of the actuating arm moves within the nozzle chamber and ejects ink therein through the nozzle opening.
