Abstract
A fluid interconnect for a fluid ejection system includes a fluid port having a fluid passage formed therethrough, and a filter provided at an end of the fluid port such that fluid passing through the fluid port passes through the filter to the fluid passage, wherein the filter is secured to an end surface and a peripheral surface of the fluid port.
Claims17
A fluid interconnect for a fluid ejection system, comprising:
- a fluid port having a fluid passage formed therethrough;
- and
- a filter provided at an end of the fluid port such that fluid passing through the fluid port passes through the filter to the fluid passage,
- wherein the filter is secured to an end surface and a peripheral surface of the fluid port, and includes a central portion extended over the fluid passage and a peripheral portion extended along a side of the fluid port,
- wherein a step is provided in the side of the fluid port, and the peripheral portion of the filter is fit within the step.
