Claim Text:
1. A compressor comprising: a valve base plate located between a suction chamber and a compression chamber, wherein a circular suction port that connects the suction chamber and the compression chamber with each other is formed in the valve base plate; a suction reed valve, which is elastically deformable and selectively opens and closes the suction port, wherein the suction reed valve is formed by: a fixed portion that is fixed to a fixing surface, the fixing surface being a surface of the valve base plate that faces the compression chamber; a base portion, which extends in a longitudinal direction of the suction reed valve from the fixed portion, wherein the base portion can be flexed; and a valve flap, which extends from the base portion toward a distal end in the longitudinal direction, wherein the valve flap selectively opens and closes the suction port, the width of the base portion is shorter than the width of the valve flap, the valve base plate has a support portion that supports a central area of the valve flap at the center of the suction port, and the suction port is formed through the valve base plate, wherein the valve base plate has a receiving portion that receives a distal area of the valve flap, and a dimension of the receiving portion in a width direction, which is perpendicular to the longitudinal direction, is greater than that of the support portion, a recessed groove is formed in the fixing surface, the recessed groove being located outside the suction port, and a sealing surface between the recessed groove and the suction port, wherein the recessed groove has a C-shape to circumferentially surround the suction port, except for a part close to the distal end in the longitudinal direction.
