Nozzle arrangement for an inkjet printer with multiple actuator devices
First Claim
1. A nozzle arrangement for an inkjet printer, the nozzle arrangement comprising:
- a wafer defining an ink supply channel, and a nozzle chamber in fluid communication with the ink supply channel;
a drive circuitry layer positioned on the wafer;
a plurality of actuator devices positioned on the wafer and the drive circuitry layer to cover the nozzle chamber; and
an ink ejection port defining means for defining an ink ejection port in fluid communication with the nozzle chamber, the plurality of thermal actuator devices being radially positioned around the ink ejection port and being electrically coupled to the drive circuitry layer so that, upon actuation, the actuator devices bend into the nozzle chamber to cause ink therein to pass through the ink ejection port.

Abstract
A nozzle arrangement for an inkjet printer includes a wafer that defines an ink supply channel and a nozzle chamber in fluid communication with the ink supply channel. A drive circuitry layer is positioned on the wafer. A plurality of actuator devices is positioned on the wafer and the drive circuitry layer to cover the nozzle chamber. An ink ejection port defining means defines an ink ejection port in fluid communication with the nozzle chamber. The plurality of thermal actuator devices is radially positioned around the ink ejection port and is electrically coupled to the drive circuitry layer so that, upon actuation, the actuator devices bend into the nozzle chamber to cause ink therein to pass through the ink ejection port.
