A one valve is disposed in the ink chamber of an ink cartridge and includes a foot support portion, a wall support portion projecting at an angle from the interior side of foot support portion, a shoulder support portion bending towards the interior side of wall support portion, and a head support portion projecting from shoulder support portion with a through hole. A valve sealing assembly being maintained selectively in contact with the head support portion through hole by a pressure difference. A sealing assembly integrally formed with a block portion is disposed at ink outlet port. The cartridge is very sensitive to pressure changes, which enhances printing quality. At the same time, the sealing assembly of the cartridge has an enhanced sealing function in non-usage status and usage status as well.
