Ink regulator tank for use with degassed inks

摘要

An ink tank for an ink delivery system includes: a first ink chamber having an ink inlet port and an ink outlet port; a second ink chamber positioned above the first ink chamber and having a roof defining a tortuous vent pathway open to atmosphere via a gas port; and a diffusion tube interconnecting the first and second ink chambers. The first ink chamber has a smaller volume than the second ink chamber and the diffusion tube minimizes diffusion of air from the second chamber to the first chamber.
