Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce a pressure loss, while securing sealability of a reed valve. SOLUTION: The reed valve 41 of a delivery port 29 has a valve plate part 41a and a valve projection part 41b formed on the tip side of the valve plate part 41a and going in and out of the delivery port 29. While forming the delivery port 29 in a tapered shape of expanding toward an outlet 29b from an inlet 29a, the valve projection part 41b is formed in a tapering-off shape having clearance with an inner surface 2a of the delivery port 29. In addition, a sheet part 22b contacting with the valve plate part 41a is formed in an outer edge part of the outlet 29b of the delivery port 29. COPYRIGHT: (C)2005,JPO&NCIPI
