PROBLEM TO BE SOLVED: To greatly improve pressure leakage from an atmosphere side to a negative pressure chamber to enhance an ejector effect.SOLUTION: In an atmosphere open two-liquid mixer, a partial weir equivalent to the area of an intermediate opening part 11 is provided in a large opening part 10 opened to atmosphere and to a distance by K from the exit of the intermediate opening part 11. As concrete means, a pin 13 is arranged, in a diameter direction, in the large opening part 10 and to the distance by K from the exit of the intermediate opening part 11, and the pin 13 is configured as the weir. Consequently, there is provided a mixer having a high ejector effect, compact in a longitudinal direction and easy to perform handling. |
