INK PUMP WITH FLUID AND PARTICULATE RETURN FLOW PATH |
摘要 |
A bidirectional sealless ink pumping system used in an inkjet printing device includes a liquid ink reservoir and a pump. The pump moves ink from the reservoir through a pumping chamber to supply ink to printheads in the printer, and moves ink from a recirculation receptacle through the pumping chamber to the reservoir. A portion of the ink in the pumping chamber is drawn out of the pumping chamber to lubricate the moving member and is filtered before returning to the pumping chamber. |
