COMPRESSOR

PROBLEM TO BE SOLVED: To provide a compressor in which the power loss can be more decreased. SOLUTION: In the compressor, the port 23b communicating a first chamber 5b with a second chamber 24 is penetrately provided to the partitions 25, 27, and the port 23b is opened and closed by the reed valve 29a. The reed valve 29a comprises a fixed part 291a fixed to a first surface 27f of the partitions 25, 27; a root 292a extending from the fixed part 291a in a first direction D1 to lift; and the valve 293a extending from the root 292a in the first direction D1 to open and close the port 23b. To the first surface 27f, a first groove 27a which surrounds the port 23b at least outside in the first direction D1, and extends to the area that overlaps with the root 292a is provided. When plan-viewing the valve 293a in the condition of the port 23b being closed, the outer edge 293e which is directed to the outside in the first direction D1 in the valve part 293a is matched with the inner edge 27e which is directed to the inside in the first direction D1 of the first groove 27a, or positioned in the inside in the first direction D1 from the inner edge 27e.
