Abstract:
1. A nozzle arrangement for a printhead integrated circuit, the arrangement having walls defining a chamber and a roof with an ink ejection port positioned on a substrate that incorporates drive circuitry, said arrangement comprising: a motion transmitting structure formed on the substrate and having an effort formation, a lever arm formation and a load formation, the lever arm formation interposed between the effort formation and the load formation; a resiliently deformable sealing structure interposed between the substrate and the lever arm formation to permit pivotal movement of the lever arm formation with respect to the substrate; a thermal bend actuator connected to the drive circuitry and being reciprocally displaceable with respect to the substrate on receipt of a signal from said drive circuitry, the actuator being connected to the effort formation; and an ink ejecting member connected to the load formation so that said reciprocal displacement of the actuator towards and away from the substrate is converted into reciprocal angular displacement of the ejecting member via the motion-transmitting structure, to eject ink in the chamber from the ink ejection port.
