PROBLEM TO BE SOLVED: To achieve a method for controlling a fluid jet device capable of switching between pulse flow jet and continuous flow jet.SOLUTION: In a method for controlling a fluid jet device that includes: a pulsating flow generation part having a fluid chamber and volume change means for changing volume of the fluid chamber for jetting fluid from a fluid jet opening as pulse flow or continuous flow fluid supply means for supplying the fluid at a predetermined pressure to the pulsating flow generation part and jet command switching means for selectively switching between pulse flow jet and continuous flow jet, the pulse flow jet and the continuous flow jet are selectively switched by the jet command switching means. In the pulse flow jet, the volume change means is driven to convert the fluid into pulsating flow to jet the fluid in a pulse form. In the continuous flow jet, the volume change means is stopped, and fluid supply pressure from the fluid supply means is increased higher than that in the pulse flow jet to jet the fluid as a continuous flow.COPYRIGHT: (C)2015,JPO&INPIT【課題】パルス流噴射と連続流噴射とを切替え可能な流体噴射装置の制御方法を実現する。【解決手段】流体噴射装置の制御方法は、流体室と前記流体室の容積を変更する容積変更手段とを有し、流体噴射開口部から流体をパルス流または連続流として噴射させる脈流発生部と、前記脈流発生部に所定の圧力で流体を供給する流体供給手段と、パルス流噴射と連続流噴射とを選択的に切り替える噴射指令切替え手段と、が備えられる流体噴射装置の制御方法であって、前記容積変更手段を駆動し流体を脈流に変換してパルス状に噴射させるパルス流噴射と、前記容積変更手段を停止し、パルス流噴射の場合よりも前記流体供給手段からの流体供給圧力を高めて流体を連続流として噴射させる連続流噴射と、に前記噴射指令切替え手段により選択的に切替える。【選択図】図5
