ABSTRACT:
Provided is a nozzle arrangement for an inkjet printhead. The nozzle arrangement includes a substrate with side walls and a roof portion together forming an ink chamber, the substrate defining an ink supply channel leading to the ink chamber, with one side wall defining an aperture. The arrangement also includes an elongate actuator extending through said aperture into the ink chamber, as well as a dynamic structure cantilevered from the side wall below the aperture. Further included is a static structure cantilevered from the side wall below the dynamic structure. The actuator is connected to the dynamic and static structures at a point distal from the aperture such that thermal expansion of the dynamic structure moves the actuator upwards in the chamber to eject ink from the chamber via a port defined in the roof portion.
