MENISKDEMPANDE DROPPGENERATOR, SERSKILT FOR BLECKSTRALESKRIVARE

摘要

A first pressure increase is effected in liquid in a pressure chamber to express liquid droplets therefrom. A time-delayed second pressure increase is effected in liquid in the same pressure chamber to effect a pressure front timed to arrive within an effective meniscus dampening vicinity of a droplet orifice at substantially the same instant that the droplet leaves the orifice to dampen substantially the full period of meniscus vibration.
