Valved discharge mechanism of a refrigerant compressor
 The present invention is directed to an improved valved discharge mechanism of a refrigerant compressor. The compressor includes a compressor housing having at least one chamber in which successive strokes of sucking, compressing, and discharging a refrigerant gas is repeatedly performed. The chamber is linked to an outside chamber through a conduit formed in the compressor housing. A valved discharge mechanism is disposed at one end opening of the conduit which opens to the outside chamber. The valved discharge mechanism includes a discharge reed valve which by means of a bending movement blocks and opens the one end opening of the conduit. The discharge reed valve has a predetermined value of elastic modulus which allows the discharge reed valve to keep blocking the one end opening of the conduit until the pressure in the chamber reaches a predetermined value. A stopper member is disposed in the outside chamber to limit the bending movement of the discharge reed valve toward the direction in which the refrigerant gas leaves from the one end opening of the conduit. An auxiliary discharge reed valve having a small curvature is proximately disposed on the discharge reed valve opposite to the one end opening of the conduit so as to enhance the value of the elastic modulus of the discharge reed valve while the discharge reed valve is bent in the direction in which the refrigerant gas leaves from the one end opening of the conduit.
