1. An ink jet nozzle arrangement comprising:
- a nozzle chamber which includes a wall defining an ink ejection port; and
an ink ejection means operatively arranged relative to the nozzle chamber, the ink ejection means being displaceable, upon activation on demand, in a direction away from a direction of ink ejection to increase a pressure in the chamber and to cause ink to be ejected from the ink ejection port.

Abstract
A nozzle arrangement for an ink jet printhead includes a wafer substrate having a nozzle chamber defined therein. The nozzle arrangement has a nozzle chamber wall that defines an ink ejection port and a rim about the ink ejection port. A series of radially positioned actuators are connected to the wafer substrate and extend radially inwardly towards the rim. Each actuator is configured so that a radially inner edge of each actuator is displaceable, with respect to the nozzle rim, into the chamber, upon actuation of the actuator and so that, upon such displacement, a pressure within the nozzle chamber is increased, resulting in the ejection of ink from the ejection port.
