Abstract
This invention relates to an ink cartridge for ink-jet printer, comprising mainly an ink storage chamber with two individually assembled parts: an ink supply adjusting valve and an air intake adjusting valve. Ink supply adjusting valve comprises a valve body, front and rear films and a filter mesh and in the valve body at least two ink chambers communicated by means of one or more ink channels are partitioned. The ink inlet of the ink supply adjusting valve is located at the lowest recessed portion of the ink chamber, while the ink outlet is connected to the ink supply port of the ink cartridge. The air intake adjusting valve, constructed of a valve core, a valve base and a valve cover, is connected to the inlet air vent of the ink storage chamber. The working pressure of the valve is adjusted by the resilient valve core.
