ABSTRACT:
An inkjet pen is disclosed having an interior chamber containing a pressure regulator. A filter within the interior chamber substantially surrounds the pressure regulator, providing a large filter surface area, and hence a low resistance to ink flow. The filter may be formed of a pleated filter material; the filter material may be retained by a rigid ink passage flange and a filter cap.
