Ink jet filtered-chamber print head |
摘要 |
In a piezoelectrically-driven printing head for a dot-matrix ink printer, the ink canals (11) have a funnel-shaped enlargement (19) connected through a filter (18) to a common ink reservoir (16). The enlargements (19) increase the ink current cross-section in the area of the filter (18) and thereby increase the ink flow rate.
