    • PROBLEM TO BE SOLVED: To suppress pressure variation and flow rate variation of fluid supplied from a pump in selectively changing over a spray nozzle for spraying the fluid, in a fluid spray device for supplying fluid to a plurality of spray nozzles from the same pump.SOLUTION: This fluid spray device includes: a plurality of dummy spray nozzles 120 arranged by respectively corresponding to a plurality of spray nozzles 20 and each performing fluid spraying equivalent to that of each spray nozzle 20; and fluid spray path changeover devices (three-way valves 50) each starting fluid spraying in the dummy spray nozzle 120 performing fluid spraying equivalent to that of an optional spray nozzle 20 in response to stop of the fluid spraying in the optional spray nozzle 20.
    • 要解决的问题:为了抑制从用于喷射流体的喷嘴选择性地切换从泵供给的流体的压力变化和流量变化,用于从流体喷射装置向多个喷嘴供应流体 相同的泵。 该流体喷射装置包括:多个虚拟喷嘴120,其分别对应于多个喷嘴20并且各自执行与每个喷嘴20相同的流体喷射; 以及在虚拟喷嘴120中开始流体喷射的流体喷射路径切换装置(三通阀50),其响应于在可选的喷嘴20中的流体喷射的停止而执行与可选的喷嘴20相当的流体喷射。 版权所有(C)2013,JPO&INPIT
