A nozzle arrangement is provided for an inkjet printhead. The nozzle arrangement includes a substrate assembly defining an ink inlet channel and an endless static wall located about the ink inlet channel. A roof structure defines an endless movable wall arranged to move along said static wall and, together with the substrate assembly, defines a nozzle chamber in fluid communication with the ink inlet channel. The roof structure further defines an ink ejection port in fluid communication with said nozzle chamber. One or more oppositely disposed pairs of actuator assemblies are mounted to the substrate assembly and extend inwardly to couple to the roof structure so that, upon actuation, the actuator assemblies can move the roof structure in a substantially rectilinear manner to vary the volume of the nozzle chamber and eject ink therein through the ink ejection port.
