PURPOSE:To obtain satisfactory mixing accuracy by providing a second fluid passage opening at the upstream side of a tapered part in a first fluid passage and a floating body movable in the tapered part. CONSTITUTION:An almost vertically attached tapered pipe 2 with its end of smaller diameter facing downward is provided on the fluid passage of the first fluid, and a floating body 3 movable freely in the tapered region is provided to the tapered pipe. Further, an inlet of the second fluid 4 to be mixed is provided to the upstream side of the tapered pipe. The first fluid 1 and the second fluid 4 are supplied respectively to the pipe. While the floating body 3 is brought into stand still in the tapered pipe 2, vortex 6 is formed behind the floating body 3; thus the first fluid is mixed with the second fluid 4. |
