PURPOSE:To shorten a mixing time as compared with that when an injection is performed by each disperser, and to improve mixing efficiency, by putting plural dispensers in simultaneous operation by single-time injecting operation. CONSTITUTION:Dispensers 1-1, 1-2... having three-way solenoid valves 3-1, 3-2... interposed in the middles of respective supplying pipes 2-1, 2-2... consists of cylinders 1-1a, 1-2a... and pistons 1-1b, 1-2b.... The valves 3-1, 3-2... consist of normally open ports NO to pipes 2-1, 2-2... to a feed liquid tank, common ports COM to the dispensers 1-1... and pipes 2-1... to a receptacle 5, and normally open ports NC. Electromagnetic attracting devices 6-1, 6-2... move forth and back together with a driving arm 7 and cooperate with magnets 1-1c... of pistons 1-1b. A dispensation driving device 8 is equipped with a reversible driving motor and a transmission mechanism which moves forth or back a driving rod 9 according to its rotational direction. |
