PURPOSE:To reduce a top clearance in a discharge opening part as well as to keep off any drop in compressive efficiency due to reexpansion, by interposing a sheet discharge plate having the discharge opening, between a cylinder and a bearing end plate at the discharge side, and installing a discharge valve on this discharge plate. CONSTITUTION:A sheet discharge plate 14 having a discharge opening 16 is interposed between a cylinder 13 and a bearing end plate 4a at the discharge side. On this discharge plate 14, there is provided with a discharge valve 7 by a bolt 9 piercing through this discharge plate 14 and being screwed in the cylinder 13. Since thickness of the discharge plate 14 is thin, a top clearance in the discharge opening 6 part becomes smaller, thus any drop in compressive efficiency due to reexpansion is prevented from occurring. |
