<P>PROBLEM TO BE SOLVED: To realize a control method for a fluid injection device capable of switching between pulse flow injection and continuous flow injection. <P>SOLUTION: The control method is for a fluid injection device comprising a fluid chamber, a volume changing means for changing the volume of the fluid chamber, a pulse flow generating part for injecting a fluid from a fluid injection opening part as a pulse flow or a continuous flow, a fluid supplying means for supplying a fluid to the pulse flow generating part by a predetermined pressure, and an injection command switching means for switching selectively between the pulse flow injection and the continuous flow injection. The injection command switching means selectively switches between the pulse flow injection of driving the volume changing means for converting a fluid into a pulse flow so as to be injected intermittently, and the continuous flow injection of stopping the volume changing means for making higher the fluid supply pressure from the fluid supplying means than in the case of the pulse flow injection for injecting the fluid as a continuous flow. <P>COPYRIGHT: (C)2011,JPO&INPIT |
