PROBLEM TO BE SOLVED: To provide a method for controlling a liquid injection device capable of switching pulse flow injection and continuous flow injection.SOLUTION: The method for controlling the liquid injection device includes: a liquid chamber a pulsating flow generation part having a volume changing means for changing a volume of the liquid chamber and injects the liquid from the liquid injection opening part as a pulse flow or a continuous flow a liquid supply means for supplying the liquid to the pulsating flow generation part at specific pressure and an injection command switch means for selectively switching the pulse flow injection and the continuous flow injection. The injection command switch means selectively switches the pulse flow injection where the volume changing means is driven so that the liquid is converted into the pulsating flow for pulsing injection, and the continuous flow injection where the volume changing means is stopped so that the liquid is injected as the continuous flow by increasing liquid supply pressure from the liquid supply means compared to in the pulse flow injection.COPYRIGHT: (C)2013,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
