These pistons are connected to the vicinity of the periphery of the swing plate 19 by rods. The connection between the rod n and the rocking plate 19 and the connection between the rod 4 and the piston are achieved by connecting the cylinder head 31 to the bolt 32 through a valve plate (9) having a ball joint with a gasket 4 and 4'. Fixed by The cylinder head 31 has a suction chamber 33 near the outer periphery and a discharge chamber M in the center. The valve plate 30 has a suction port that connects the cylinder 26 to the suction chamber, and a discharge port that connects each of the cylinders to the discharge room temperature, and is integrally fixed to the cylinder block 11 with a fixing bolt 32. has been done.
前記薄板状ガスケット２９・四′はシリンダ部（吸入口
及び吐出口）に開口部を有しており。The thin plate gasket 29/4' has an opening in the cylinder portion (intake port and discharge port).

全く関係１ないデッドクリアランスＤを形成することに
なシ圧縮機の圧縮効率を低下させる原因になってりた。For this reason, especially during compression (when the suction port is closed), the area between the suction valves is completely affected by the volume change due to the reciprocating movement of the screws and screws between the valve plate I and the piston rear, as shown in Figure 10. This results in the formation of a dead clearance D that is not equal to 1, which causes a reduction in the compression efficiency of the compressor.
