-1- Abstract: A compressor has a hermetic shell defining a compression chamber for compressing a fluid, such as refrigerant gas, the compressed gas being discharged from the compression chamber through a discharge port. A valve arrangement is provided at the discharge port for permitting flow of the gas in only one direction, i.e. from inside to outside of the compression chamber. This valve arrangement comprises first and second resilient elongated plates, each having first and second ends. The first ends are rigidly connected to the hermetic shell and the second ends are located in layers over the discharge port. The second end of the first plate, which is located directly over the discharged port, has at least one opening, so that the pressure gas discharged from the discharge port strikes partly on the first plate and partly on the second plate through the opening. In this way, the vibrations of these plates caused by any rapid change in the amount of flow of gas from the discharge port can be suppressed, resulting in a more quiet running compressor than has been available in the past.
