    Abstract: Systems and related methods are described for circulating and printing fluid onto a printer media. In one example, a system can include an air isolation chamber to pool printing fluid circulated within the system. The air isolation chamber can be fluidly connected to a printhead assembly to eject a portion of the printing fluid onto the printer media. The system can further include a pump to pump printing fluid from the air isolation chamber to the printhead assembly. The system can further include a pressure control valve along a return line between the air isolation chamber and the printhead assembly to regulate the flow of unejected printing fluid to the air isolation chamber to control printing fluid pressure over the printhead assembly.

    Abstract: A fluid container usable with an image forming apparatus is disclosed. The fluid container includes a housing unit, a free-fluid chamber disposed in the housing unit and configured to store fluid, and a regulated chamber disposed in the housing unit. The regulated chamber includes a regulator unit, an outlet and a plurality of states. The regulator unit is configured to regulate respective fluid therein. The outlet is configured to transport the respective fluid from the regulated chamber. The fluid container also includes a plurality of valves disposed in the housing unit. At least one of the valves is configured to selectively stop fluid communication between the regulated chamber and the free-fluid chamber based on the respective state of the regulated chamber.

    Abstract: An integrated multifunctional valve device includes a surface member having a first port and a second port formed therein, a flexible disk member having a central portion and a surrounding portion, a first seat member extending outward from the surface member and coupled to the surrounding portion of the flexible disk member, a second seat member extending outward from the surface member and surrounded by the first seat member. The central portion is movable between an open port position to establish fluid communication between the respective ports and a close port position to stop the fluid communication between the respective ports. The second seat member is configured to selectively receive the central portion of the flexible disk member corresponding to the close port position. The integrated multifunctional valve device also includes an actuator member configured to selectively move the central portion of the flexible disk member into the open port position and the close port position.

    Abstract: An ink supply (24) for a push-primed inkjet printer (20) including an ink reservoir (52), a housing (56), and a pair of valves (66, 68). The housing (56) may enclose the ink reservoir (52) and define an opening (84) that provides fluid communication between the ink reservoir (52) and outside the housing (56). The pair of valves (66, 68) may be coupled to the housing (56), arranged in series, and configured to control the fluid communication.
