Claim:
1. A compressor, comprising: a housing; a compression chamber defined in the housing, wherein refrigerant is compressed in the compression chamber; a suction chamber defined in the housing, wherein the refrigerant is drawn into the compression chamber through the suction chamber; a valve base plate located between the compression chamber and the suction chamber; a suction valve plate provided over the valve base plate; a plurality of suction ports formed in the valve base plate to extend through the valve base plate, wherein the plurality of suction ports is capable of connecting the compression chamber and the suction chamber with each other; and a plurality of suction reed valves for selectively opening and closing the plurality of suction ports, the plurality of suction reed valves being defined by apertures penetrating the suction valve plate to form spaces in the suction valve plate and define outer profiles of the plurality of suction reed valves, wherein each of the plurality of suction reed valves has an elongated shape with a distal end and is elastically deformable, each of the suction reed valves including: a fixation portion fixed to the valve base plate, a basal portion that extends from the fixation portion in the longitudinal direction of the suction reed valve and is separable from the valve base plate, and a valve flap that extends from the basal portion toward the distal end in the longitudinal direction of the suction reed valve to selectively open and close the suction port, the valve base plate has a fixation surface that faces the compression chamber, wherein the fixation portion is fixed to the fixation surface, a corresponding one of the suction ports having a shape elongated in a width direction, which is orthogonal to the longitudinal direction of a corresponding one of the suction reed valves, the width of a corresponding one of the basal portions is set to be greater than the measurement of the corresponding one of the suction ports in the width direction, the valve flap includes an opening-closing portion that faces the suction port, a pair of stoppers projecting from the opening-closing portion at both ends in the width direction of the corresponding one of the suction ports, wherein the stoppers protrude in opposite directions from each other, and an outermost side of each of the pair of stoppers is arcuate, and a pair of side edges, which encompasses the outermost side of each of the pair of stoppers, the pair of side edges extending continuously from the outermost side of the pair of stoppers to the corresponding one of the basal portions, wherein the pair of side edges approach each other in a direction from the distal end of the corresponding one of the suction reed valves toward the corresponding one of the basal portions so as to define a minimum width of the corresponding one of the basal portions, wherein the outermost side of each of the pair of stoppers entirely diverge from each other in a direction towards a free end of the valve flap to define a maximum width of the valve flap, the spaces being provided so as to extend along each of the pair of side edges, the housing has a pair of retainers, wherein each stopper contacts one of the retainers, and wherein refrigerant in the suction chamber is configured to be drawn into the compression chamber through the spaces.
