<p>PROBLEM TO BE SOLVED: To improve structure causing the lowering of airtightness and increase in the cost in a conventional fluid compressor. SOLUTION: The fluid compressor is so formed that a fluid channel 4 is formed of inner members 9, 10, and 20 in the inside of a casing having a cylinder shell plate 21, and the casing has a horizontally split type welding structure formed by joining a semicylindrical top half casing and a bottom half casing with flanges 22 for horizontal joining welded thereto respectively by bolt fastening via the flanges 22. The end closing inner member 22 used for closing the left/right side ends of the channel out of the inner members is brought in contact with the inner circumferential face of the shell plate 21 of the casing and an O ring 23 for sealing is interposed between the side of the end closing inner member and the internal circumference of the casing.</p> |
