摘要：
PROBLEM TO BE SOLVED: To achieve a liquid ejection method where an excision force and an excision speed can be adjusted independently.SOLUTION: The liquid ejection method related to a liquid ejection apparatus 1 includes: a pulse generation part 20 for ejecting a liquid so that the liquid is made to be pulsed from a liquid ejection inlet 96 by changing capacity in a pressure chamber 80 using a piezoelectric element 30 and a diaphragm 40 and a pump 10 for supplying the liquid into the pulse generation part 20. The method changes an amount of a liquid supplied from the pump 10 and a frequency (equivalent to a drive frequency of the piezoelectric element 30) of capacity change of the pressure chamber 80 in a relative relation. A capacity change amount (excluded volume) of the pressure chamber 80 changes the excision force, and product of the excluded volume and the drive frequency change the excision speed. Thus, the excision force can be adjusted independent from the excision speed.COPYRIGHT: (C)2012,JPO&INPIT【課題】切除力と切除速度を独立して調整可能な流体噴射方法を実現する。【解決手段】流体噴射装置1に係る流体噴射方法は、圧力室80の容積を圧電素子30及びダイアフラム40により変化させて流体噴射開口部96から流体をパルス状に噴射する脈流発生部20と、脈流発生部20に流体を供給するポンプ10と、が備えられ、ポンプ10から供給される流体供給流量と、圧力室80の容積変化の周波数(圧電素子30の駆動周波数に相当)と、を比例の関係で変化させる。圧力室80の容積変化量(排除体積)は切除力を変化させ、排除体積と駆動周波数の積は切除速度を変化させることから、切除力と切除速度を独立して調整できる。【選択図】図6
