A valve plate assembly of a compressor of the present invention comprises: a valve plate in which a suction port is formed; and a suction reed which opens and closes the suction port. The suction port comprises a first suction port at an inlet and a second first suction port at an outlet, wherein the area of the second first suction port is wider than that of the first suction port. Accordingly, the suction port consisting of the first and second suction ports has a wide area thereof, thereby preventing the flow rate of sucked refrigerants from increasing and minimizing the drop of pressure of the sucked refrigerants.
