ABSTRACT:
The present invention provides any ink jet pen an apparatus for storing and printing ink, wherein a valve is connected between the ink reservoir and the ink chamber for controlling the ink flow between the ink reservoir and the ink chamber and adjusting the air pressure in the ink chamber to keep the pressure in the ink chamber within the allowed range as the ink gradually gets depleted or the environmental pressure changes. The valve having a plunger and a plunger chamber, wherein the plunger chamber is connected to the atmosphere via an atmospheric opening and connected to the ink chamber via a feedback opening which adjusts the pressure in the ink chamber to move the plunger. When a difference between the atmospheric pressure and inner pressure of the ink chamber develops, the plunger will be pushed by the pressure of the atmosphere or the ink chamber to determine whether the ink reservoir is connected to the ink chamber and to adjust the ink chamber inner pressure. Therefore, the cartridge can provide a proper ink supply and thorough ink usage and leakage prevention.
