摘要： PURPOSE:To obtain stable performance by eliminating the variations in the jetting efficiency with time, particularly the lowering of the jetting efficiency at high temperatures, by a method in which a vibrating part is connected through a vibration absorber to an ink jet head in such a way as to provide no or extremely damped resonance characteristics to the frequency characteristics of the ink jet head. CONSTITUTION:Ink liquid is jetted into air in the form of fine jet stream through an ink liquid chamber 2 and a nozzle orifice 4. On the other hand, when a voltage is applied to a piezo-vibrating element 7 from the outside power source 10, a flexing (bending) vibration occurs in the vibrating plate 6, and the vibration is transmitted to ink liquid to form a standing wave in the ink chamber. Although the ink jet head comes to have the resonance characteristics of frequency which are determined by the dimension (mainly length) of the ink chamber and acoustic wave in the ink, since the structure has a vibration absorptive sheet 8, the resonance characteristics become damped ones.
摘要翻译：目的：为了获得稳定的性能，通过消除喷射效率随时间的变化，特别是降低高温喷射效率，通过振动部分通过减振器连接到喷墨头的方法以便为喷墨头的频率特性提供没有或极其阻尼的共振特性。构成：油墨液体通过墨液室2和喷嘴孔4以细喷射流的形式喷射到空气中。另一方面，当从外部电源10向压电振动元件7施加电压时在振动板6中发生弯曲（弯曲）振动，并且振动被传送到墨液体，以在墨室中形成驻波。虽然喷墨头具有由油墨室的尺寸（主要是长度）和油墨中的声波确定的频率的共振特性，但是由于该结构具有吸振片8，所以共振特性变得阻尼。
