Integrated multifunctional valve device

A fluid container usable with an image forming apparatus, the fluid container comprising:

• a housing unit including a free-fluid chamber and a regulated chamber to store fluid and separated by a common wall, the regulated chamber including a regulator unit to regulate the respective fluid therein;
• and
• an integrated multifunctional valve device disposed on the common wall of the housing unit, the device comprising:
• a port member having a first port and a second port formed therein;
• a flexible disk member having a central portion and a surrounding portion, the central portion 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;
• a first seat member extending in a first direction from a surface of the port member and coupled to the surrounding portion of the flexible disk member;
• a second seat member extending in the first direction from the surface of the port member and surrounded by the first seat member, the second seat member extending to a lesser extent from the surface of the port member relative to the first seat member, the second seat member to selectively receive the central portion of the flexible disk member corresponding to the close port position;
• and
• an actuator member to selectively move the central portion of the flexible disk member between the open port position and the close port position, the actuator member comprising:
• an actuator ball;
• and
• a lever member movable between a plurality of positions, the lever member to move the actuator ball relative to the second seat member based at least on the respective position of the lever member.

• a first seat member extending in a first direction from a surface of the port member a first distance, the first seat member to support the surrounding portion of the flexible disk member;
• a second seat member extending in the first direction from the surface of the port member a second distance less than the first distance and surrounded by the first seat member, the second seat member to selectively receive the central portion of the flexible disk member corresponding to the close port position;
• and
• an actuator member to selectively move the central portion of the flexible disk member between the open port position and the close port position.
