課題を有していた。Problems to be Solved by the Invention However, in the configuration as described in 1, the air cylinders 2A, 2B
If the roundness of the parallel air holes 13 is poor, or due to dimensional errors in the spacer 11 or the convex portion of the air cylinder 2B, the gaps between the parallel air holes 14 may become uneven, and the air flowing into the parallel air chamber 12 from the parallel pneumatic rectifier hole 13 may become uneven. Since the air is biased by the spacer 11 and the convex portion of the air cylinder 2B, the parallel air ejected from the parallel air holes 14 is non-uniform. Therefore, air cylinder 2A, throttle cylinder 1
Since parallel air does not flow uniformly over the surface of 7, soot adheres and grows in places where there is little parallel air, and the temperature of the iris tube 17 rises, causing thermal deformation and high-temperature corrosion of the iris tube 17. I had an issue.
