PROBLEM TO BE SOLVED: To prevent discharge of impurities from an exhaust part.SOLUTION: A filter 12 has a cylindrical body 24 and a pressure mitigation material 25 and is arranged in an in-tank space 22 of a tank body 11. A partition plate 13 is arranged below the filter 12 in the in-tank space 22, and partitions the in-tank space 22 into an in-tank upper space 49 and an in-tank lower space 50. A flow force of a mixture flowing into an in-filter space 30 from an inflow part is mitigated by the pressure mitigation material 25, and the mixture is separated into a gas and impurities, and flows out from through-holes 29. The impurities separated from the mixture are stored at a bottom part 46 of the in-tank lower space 50, and the gas separated from the mixture is exhausted to the outside from an exhaust part. The partition plate 13 does not have a hole for communicating the in-tank upper space 49 and the in-tank lower space 50, and a gap 51 for communicating the in-tank upper space 49 and the in-tank lower space 50 is formed between the partition plate 13 and an inner surface of the tank body 11.SELECTED DRAWING: Figure 6 |
