CONSTITUTION:An input signal is applied to a piezoelectric vibrator 19 to propagate an internal pressure of an injection chamber 11 to a capacity chamber 14. A back pressure, generated in a jet nozzle aperture part 10, increases the internal pressure in the capacity chamber 14, and an ink current is jetted through the jet nozzle aperture 10 with the pressure. The increase in the internal pressure in the capacity chamber 14 enables ink to backflow to an ink chamber 13 through an ink feed hole 15 to rapidly reduce the internal pressure in the capacity chamber 14. An ink liquid pressure oscillation is partially absorbed in the capacity chamber 14, which results in preventing an influence from being exercised directly upon the jet nozzle aperture 10.,下面是Injecting head专利的具体信息内容。
