Patent abstract
A fluid ejection device that can be used for inkjet heads is described. A large actuator with a small stroke in combination with hydraulic pressure transfer by means of essentially relatively incompressible fluid is used in order to generate a large stroke of a small membrane. Further the ink is ejected during the actuation phase of the actuator enabling a better control of the droplet dynamics.
