INK SUPPLY VALVE OF WET ELECTRO-PHOTOGRAPHIC PRINTER

摘要

PURPOSE: An ink supply valve of a wet electro-photographic printer is provided to quantitatively supply ink by spacing a valve lift from an ink passage. CONSTITUTION: An ink supply valve includes a valve body(410), a rod assembly(420), a lift unit(430) and a corrugated tube(440). The valve body has a selectively opened pipeline(400) for communicating a condensed ink tank(140) with a developer tank(100). The lift unit moves the rod assembly within a specific stroke distance. The corrugated tube avoids the intrusion of ink into a lift unit operating chamber(400b) by dividing the pipeline into an ink passage(400a) and the lift unit operating chamber. Herein, the lift unit operates smoothly regardless of the sticking of ink. Therefore, quantitative ink supply is possible.
