Abstract: A compressor valve structure permits improvement in durability and volumetric efficiency of a compressor and limits power losses. The width of the base portion of each suction reed valve is shorter than the width of the valve flap. The valve base plate has support portions, receiving portions, main coupling portions, and auxiliary coupling portions. Each support portion receives a central area of corresponding one of the valve flaps. The receiving portion receives a distal area of the valve flap. The main coupling portion extends from the support portion and couples the support portion to the receiving portion. The auxiliary coupling portion extends from the support portion. The suction ports are formed through the valve base plate, while leaving the support portions, the receiving portions, the main coupling portions, and the auxiliary coupling portions.
