Ink cartridge for inkjet printer, has low pressure generating mechanism which selectively closes/opens fluid path by using elastically deformable valve

摘要

A low pressure generating mechanism (30) selectively opens/closes fluid flow path between ink storage chamber (17) and supply port (5). An elastically deformable valve (20) having a through hole (200), contacts/separates from the opening (7) of the fluid flow path. Independent claims are included for the following: (1) fluid flow controller for recording head; and (2) method of regulating ink flow.
