Wideband ink drop generator

摘要

A wideband ink jet drop generator for breaking up one or more capillary ink streams emanating from the generator, into a regular succession of drops. The drops are of uniform size and uniformly spaced. The generator includes an orifice support plate with a cavity on one surface. A nozzle wafer with one or more orifice is mounted on the opposite surface of the plate. The orifices are in fluidic communication with the cavity. A pair of elongated crystals are disposed on the cavity surface of the support plate. The crystals are configured in spaced relation with the orifices of the nozzle wafer positioned between the crystals along a line whereat pressure waves emanating from the crystal are reinforced.
