摘要： A printing system includes a liquid drop ejector, a fluid flow device, and a fluid flow source. The liquid drop ejector is operable to eject liquid drops having a plurality of volumes along a first path. The fluid flow device includes a first section comprising a plurality of sub-channels created by a partition and a second section comprising a plurality of sub-channels created by a partition. Each partition has a height as viewed from a wall of the fluid flow device. The height of the partition of the second section is less than the height of the partition of the first section. The fluid flow source is operable to produce a fluid flow through the fluid flow device. The fluid flow interacts with the liquid drops to cause liquids drops having one of the plurality of volumes to begin moving along a second path.

摘要： A continuous drop emitter comprising a liquid supply chamber containing a liquid held at a positive pressure; first and second nozzles in fluid communication with the liquid supply chamber nozzles emitting first and second continuous streams of a liquid; first and second stream break-up transducers adapted to independently synchronize the break up of the first and second continuous streams of the liquid into first and second streams of drops of predetermined volumes, respectively; and an acoustic damping material located adjacent to or within the liquid supply chamber for damping sound waves generated within the liquid chamber by the first and second stream break-up transducer. The continuous drop emitter may also configured with a Helmholtz resonant chamber tuned to a critical stimulation frequency having an acoustic damping material therein for absorbing acoustic stimulation energy. The Helmholtz resonant chamber may serve as a portion of the common liquid supply for the first and second jets in which case the acoustic damping material may be porous to allow the liquid to pass through. The acoustic damping materials may acoustically lossy materials that transmute energy into heat via molecular motions. The acoustic damping materials may be porous materials that absorb acoustic energy by forcing the liquid through small passages causing viscous flow energy losses. In addition the acoustic damping materials may include components that cause the disruption of acoustic waves by reflection from materials that are impedance mismatched to the liquid, either very dense materials or gas filled voids.

摘要： A drop generator operable to selectively form a drop having a first size and a drop having a second size from liquid emitted through a nozzle associated with the drop generator. The drop having the first size and the drop having the second size travel along a drop trajectory with the first size being larger than the second size when compared to each other. Each of the drops has a drop velocity. A gas flow deflection system includes a gas flow that is directed at a deflection zone that comprises at least a portion of the drop trajectory. The gas flow in the deflection zone includes a velocity vector having a parallel velocity component and a perpendicular velocity component with the parallel velocity component and the perpendicular velocity component being defined relative to the drop trajectory.
