Ink jet printhead having a moving nozzle with an externally arranged actuator

摘要

A nozzle assembly 10 for an ink jet print head includes a substrate 16. At least one nozzle 22, defining a nozzle opening 24, is arranged on the substrate 16. The nozzle opening 24 is in communication with a nozzle chamber 34. The nozzle 22 is displace able relative to the substrate 16 for effecting ink ejection from the nozzle chamber 34 through the nozzle opening 24 on demand. An actuator 28 is arranged externally of the nozzle 22 and is connected to the nozzle 22 for controlling displacement of the nozzle 22.
