    摘要: An ink jet printhead assembly for a pressure controlled ink jet printhead. The assembly includes an ink reservoir made of a first material having a first melting point and having an open top cavity defined by sidewalls, a bottom wall and a peripheral edge. A pressure control structure made of a polymeric material having a second melting point lower than the first melting point is included. The pressure control structure has a first surface, a second surface opposite the first surface, a side surface, and an aperture therein. A sealing structure for forming a liquid tight seal is provided between the sidewalls of the ink reservoir and the side surface of the pressure control structure. A pressure regulating film is attached over the aperture to the first surface of the pressure control structure. A cover is attached to the ink reservoir.

    摘要: A regulator adapted to regulate the throughput of an ink between an ink source and a print head includes: (a) a pressurized chamber including an ink inlet in fluid communication with the ink source, an ink outlet in fluid communication with the print head, and at least one flexible wall; and (b) a lever including a flexible arm extending along a portion of the flexible wall and an opposing arm operatively coupled to a seal biased to close the ink inlet when the lever is in a first position and to open the ink inlet to allow fluid communication between the ink inlet and the pressurized chamber when the lever is pivoted to a second position; where a lower pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm, pivoting the lever to the first position (inlet closed), where a higher pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm to pivot the lever to the second position (inlet open), and where a pressure change from the lower pressure differential to the higher pressure differential across the flexible wall causes the flexible wall to actuate and flex the flexible arm without causing the lever to pivot.
