Inkjet nozzle comprising a motion-transmitting structure

1. An inkjet nozzle comprising:

a displaceable actuator arm;

a paddle for ejecting ink through an aperture defined in a roof of the nozzle; and

a motion-transmitting structure interconnecting the actuator arm and the paddle, wherein the motion-transmitting structure comprises:

an effort formation;

a lever arm formation; and

a load formation,

wherein the lever arm formation is interposed between the effort formation and the load formation.

2. The inkjet nozzle of claim 1 , wherein the effort formation extends from a working end of the actuator arm.

3. The inkjet nozzle of claim 2 , whereby upon reciprocal movement of the working end of the actuator arm, the lever arm formation pivots.

4. The inkjet nozzle of claim 3 , whereby the pivotal movement of the lever arm formation results in angular displacement of the paddle.

5. The inkjet nozzle of claim 1 , wherein the load formation extends from an end portion of the paddle.

6. The inkjet nozzle of claim 1 , wherein the lever arm formation is pivotally connected by connectors to the nozzle arrangement.

7. The inkjet nozzle of claim 6 , wherein the connectors are opposed flexural connectors.

8. The inkjet nozzle of claim 7 , wherein the flexural connectors are torsionally distorted upon pivotal movement of the lever arm formation.

9. The inkjet nozzle of claim 1 , wherein the load formation forms part of an end wall of the nozzle.

10. The inkjet nozzle of claim 1 , wherein the load formation and the effort formation are composite formations with a primary layer and secondary layer.

11. The inkjet nozzle of claim 10 , wherein the primary layer is formed from TiAIN and the secondary layer is formed from titanium.

12. The inkjet nozzle of claim 1 , wherein the paddle is fixed to the load formation.

13. The inkjet nozzle of claim 1 , wherein the paddle extends towards a distal end wall.

14. The inkjet nozzle of claim 1 , wherein at least a portion of the paddle has corrugations.
