NOZZLE ARRANGEMENT WITH AN ACTUATOR HAVING IRIS VANES |
摘要 |
A nozzle arrangement for an inkjet printhead includes a substrate defining an ink inlet; a plurality of posts extending from the substrate; a roof portion defining an ejection port, the roof portion supported by the plurality of posts; a plurality of vanes extending from the substrate and arranged to form a wall of a chamber around the ink inlet; and a plurality of thermal bend actuators respectively positioned at a base of each vane, each thermal bend actuator having a fixed end in the vicinity of one of the plurality of posts and a displaceable end opposite the fixed end. The plurality of thermal bend actuator are adapted to bend said vanes inwards with respect to the chamber in an iris-type manner to reduce a volume of the chamber, whereby ink is ejected from the chamber via the ejection port.
