PURPOSE:To secure the optimum suction timing by obtaining a plurality of divided valve pieces with a fixed edge side in common and forming the rate of the width between the fixed edge part and the movable edge part of the valve piece different. CONSTITUTION:In a reed valve 22, three valve pieces 22d-22f are integrally formed by two slit-shaped cut parts, and said valve pieces are opposed to the respective valve holes 21d-21f. The width of the root 22e1 of the valve piece 22e at the center is formed narrower than that of the movable edge, and each width of the roots 22d1 and 22f1 of the valve pieces 22d and 22f on the both sides is formed larger than that of the movable edge. Therefore, the spring constant of the valve piece 22e is made smaller than each spring constant of the valve pieces 22d and 22f, and the valve opening pressure of the valve piece 22e is reduced than each valve opening pressure of the valve pieces 22d and 22f. |
