PROBLEM TO BE SOLVED: To reduce discharge pressure loss and prevent a discharge valve from being damaged. SOLUTION: Chamfering 13A fitted at the lower edge of a discharge part 13 is a elliptic shape and a straight line X of the elliptic shape along to a long side of the discharge valve 17 is formed a large diameter and a line Y vertically crossing the discharge valve 17 is formed as a small diameter; and then, as the length of the outer circuit of a discharge hole increases, the cross section area of the discharge port 13 and a discharge area set at product calculated by the head height of the discharge valve 17 and the length of the outer circuit of the hole of the edge surface head diameter of the discharge port is increased and enables to reduce discharge pressure loss. Accordingly, efficiency as a refrigerant compressor is improved.
