Abstract

A nozzle arrangement for a printhead integrated circuit is provided having a fluid chamber having a fluid ejection port, a fluid ejecting member displaceable within the chamber to eject fluid from the ejection port, an actuator for causing displacement of the ejecting member from outside the chamber, and a resiliently deformable seal on the chamber for fluidically sealing the chamber about the ejecting member.

Claims

1. A nozzle arrangement for a printhead integrated circuit, the arrangement comprising:

a fluid chamber having a fluid ejection port;

a fluid ejecting member displaceable within the chamber to eject fluid from the ejection port;

an actuator for causing displacement of the ejecting member from outside the chamber; and

a resiliently deformable seal on the chamber for fluidically sealing the chamber about the ejecting member.

2. A nozzle arrangement as claimed in claim 1, wherein the chamber has a fluid inlet channel aligned with the ejection port with the ejecting member therebetween.

3. A nozzle arrangement as claimed in claim 1, wherein the ejecting member is corrugated.

4. A nozzle arrangement as claimed in claim 1, wherein chamber comprises a distal end wall, a proximal end wall and a pair of opposed sidewalls to define a rectangular chamber, a roof defining a rim about the ejection port and a recess positioned about the rim.
