摘要：
PROBLEM TO BE SOLVED: To provide a fuel injection method capable of independently adjusting a cutting force and a cutting speed.SOLUTION: The fuel injection method relating to a fuel injection apparatus 1 includes a pulsating flow generation part 20 for injecting a fluid in a pulse shape from a fluid injection opening 96 while changing capacity of a pressure chamber 80 through a piezoelectric element 30 and a diaphragm 40 and a pump 10 for supplying the fluid to the pulsating flow generation part 20, and proportionally changes a fluid supply flow rate supplied from the pump 10 and a frequency of a capacity change of the pressure chamber 80 (corresponding to a drive frequency of the piezoelectric element 30). A capacity change amount (exclusion capacity) of the pressure chamber 80 changes a cutting force and a product of the exclusion capacity and the drive frequency changes a cutting speed, such that the cutting force and the cutting speed can be adjusted independently.COPYRIGHT: (C)2015,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
