<P>PROBLEM TO BE SOLVED: To provide a fluid injecting apparatus which can be driven by a compact pump. <P>SOLUTION: The fluid injecting apparatus 100 includes: a pulsation generator 30 for changing the volume of a fluid room to inject a pulsation flow; a fluid supplier 10 for supplying the pulsation generator 30 with a fluid; a drive controller 50 for inputting each of them with a driving signal; and a work instruction inputting center 40, wherein both a fluid supply driving signal for driving the fluid supplier 10 to supply the pulsation generator 30 with the fluid and a pulsation flow driving signal for driving a volume changing means to inject the fluid as a pulsation flow are input to interconnect with the input of a work instruction. Briefly, the injection and termination of the fluid, the generation and termination of the pulsation flow, and the supply of water into a pump can be interconnected with each other. Consequently, the fluid supply driving signal and the pulsation flow driving signal can be interconnected with each other to limit continuous injection within a necessary and sufficient extent, allowing to keep so small the volume of the fluid in the fluid supplier that even a compact pump can provide a necessary and sufficient continuous injection. <P>COPYRIGHT: (C)2012,JPO&INPIT |
