摘要： A replaceable pump module for an ink-jet printer is configured to receive a replaceable ink supply including a reservoir having a fluid outlet. The replaceable pump module includes a variable volume chamber having a fluid inlet adapted to form a fluid connection with the fluid outlet of the ink supply reservoir. The variable volume chamber has a check valve which allows the flow of ink from the reservoir to the chamber and limits the flow of ink from the chamber to the reservoir. The replaceable pump module chamber also includes a fluid outlet. When the replaceable pump module is installed in a printer, the pump module fluid outlet establishes a fluid connection between the chamber and a fluid inlet of the printer. The chamber is part of a pump provided with the replaceable pump module that can be actuated to supply ink from the reservoir to the printer.

摘要： The present invention relates to free-ink type ink-jet pens and, more particularly, to a method and apparatus for purging air from an on-axis ink accumulator. A biased regulator mechanism is provided within the pen to allow ink from a pressurized ink reservoir to be fed to the pen while maintaining a predetermined set point back-pressure at the printhead as needed for appropriate pen operation. A mechanism in communication with the ambient atmosphere is used in conjunction with a substantially constant force biasing mechanism to maintain the balance between the countervailing forces. Back-pressure is maintained substantially constant regardless of the ink flow rate from the ink reservoir into the accumulator. By application of a positive pressure to the ambient atmosphere mechanism, the biased regulator mechanism is forced open and any gas bubbles trapped within the accumulator is forced out through the reservoir ink feed.

摘要： A fail-safe, stop valve for an ink-jet print head in a pressurized ink delivery system. The stop valve is actuated by a back pressure regulator if the operating pressure of the print head approaches atmospheric pressure during operation.
