1. a kind of fluid actuator (1), its fluid for flowing through the fluid actuator (1) by injection influences to flow along flow surfaceDynamic, the fluid actuator includes:

  • At least two in passing away (21,22 of the respective end provided with outlet;

    121、

    122、

    123), wherein in the end of the passing away (121,122,123), the width of the passing away (B121, B122,B123) increase and depth reduction, so that the area of section of each bar passing away (121,122,123) is logical relative to the dischargeEach area of section of the outlet (141,142,143) in road (121,122,123) is held essentially constant, wherein, the dischargeThe degree of lip-rounding turns into slot type, and the depth with 0.2cm~0.8cm and 20cm~100cm width;

    Be connected to the dischargePassage (21,22;

    121st, 122,123) and for supplying the feed path (31 of fluid under feed pressure;

    131);

    Flow direction deflectionDevice (50), the feed path (31;

    131) it is bound to and described flows to arrangement for deflecting and the passing away (21,22;

    121、

    122nd,

         123) from it is described flow to arrangement for deflecting in reveal;

    With actuation means (60;

    160), the actuation means are connected to instituteState flow to arrangement for deflecting (50) for encourage it is described flow to arrangement for deflecting, it is described flow to arrangement for deflecting be suitable to make the fluid withCyclic sequence is continuously guided to passing away every described (21,22;

    121、

    122、

    123).
