An example apparatus includes a housing including a first chamber and a second chamber, the housing defining a first port to fluidly couple the first chamber to a printer, the housing including a second port to fluidly couple the first chamber and the second chamber; a bladder disposed in the first chamber, the bladder being inflatable to increase a pressure within the first chamber; and a regulator to regulate fluid flow from the second chamber to the first chamber and to deter fluid flow from the first chamber to the second chamber.

Fluid containers

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.

Fluid container having plurality of chambers and valves

A fluid container includes a housing unit including a free-fluid chamber, a regulated chamber, and a plurality of valves. The free-fluid chamber is configured to store fluid. The regulated chamber includes an air bag assembly, an outlet, and a plurality of states. The air bag assembly is configured to regulate respective fluid therein and includes at least one air bag including an internal chamber having a volume capacity. The outlet is configured to transport the respective fluid from the regulated chamber. At least one of the plurality of 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.
