NOZZLE ARRANGEMENT INCLUDING ACTIVE AND STATIC INK EJECTING MEMBERS DEFINING VARIABLE-VOLUME CHAMBER |
摘要 |
A nozzle arrangement for an inkjet printhead includes an ink inlet; a static ink ejecting member bounding the ink inlet; an active ink ejecting member having a roof defining an ink ejection port and sidewalls depending from the roof, the active ink ejecting member and the static ink ejecting member together defining a nozzle chamber; and an actuator arrangement for reciprocating the active ink ejection member relative to the static ink ejecting member. The static ink ejecting member includes a sealing structure defined along an edge thereof, the sealing structure shaped to form a fluidic seal between the active and the static ink ejecting members by surface tension of a fluid in the nozzle chamber. |
