<p>PURPOSE:To improve the noise reducing effect of the titled enricher by providing >=4 bends to each of the atmosphere inlet passage and the atmosphere outlet passage of a soundproof box and furnishing a sound absorbing material at the bend on the inside of the atmosphere passages. CONSTITUTION:The atmosphere D flows in from an atmosphere intake 34, and flows through the bent atmosphere inlet passage from (1) (2) (3) (4), since the chamber is provided with a partition plate 40. The atmosphere passes through an opening part 35, flows through the bent passage from (5) (6) (7) (8), flows through a sound absorbing box 32, flows through the bent passage from (9) (10), flows into the soundproof box E to cool a compressor, etc., in the box, then goes out from an atmosphere outlet opening part 37, passes through the bent atmosphere outlet passage from (1) (2) (3) (4) (5) separated by the partition plates 42 and 43, and is discharged as (G) from the atmosphere discharge part 39 to the outside of the device. Since the sound absorbing material is provided at each bend of the passage, the exhaust sound is reduced. Besides, the atmosphere is sucked from another port, and enriched O2 is generated by pressure swing adsorption.</p> |
