Abstract
An inkjet ejector has been developed that enables the ejector to be operated at a frequency greater than 80 kHz. The inkjet ejector includes a body layer in which a pressure chamber is configured with an outlet having a volume that is less than a predetermined volumetric threshold, a flexible diaphragm plate disposed on the pressure chamber to form a wall of the pressure chamber, a piezoelectric transducer having a bottom surface attached to the diaphragm plate, and an inlet layer in which an inlet channel is configured to connect the pressure chamber to a source of liquid ink, a cross-sectional area of the inlet channel at the pressure chamber divided by a length of the inlet channel being greater than a predetermined linear threshold.
