Abstract
A nozzle arrangement for an inkjet printhead. The nozzle arrangement comprises a substrate incorporating drive circuitry and defining an ink inlet channel; side walls extending from the substrate; a roof fast with the side walls and defining an ink ejection port in fluid communication with an ink chamber defined by the roof, the side walls, and the substrate, the ink chamber being in fluid communication with the ink inlet channel; an ink ejection member interposed between the ink inlet channel and the ink ejection port such that reciprocal movement of the ink ejection member causes ejection of ink from the ink ejection port; an actuator connected to the drive circuitry at a fixed end and having a free end reciprocally displaceable with respect to the substrate on receipt of an electrical signal from the drive circuitry; and a motion transmitting structure interposed between the free end of the actuator and the ink ejection member. The motion transmitting structure has an effort formation, a lever arm formation, and a load formation interconnecting the effort formation and the lever arm formation. The effort formation is adapted to engage with the free end of the actuator arm, and t…
