<p>A compressor has a hermetic shell defining a compression chamber for compressing a fluid such as refrigerant gas supplied therein. The compressed gas is discharged from the compression chamber through a discharge port. A valve arrangement is provided at the discharge port for permitting the flow of the gas only in one direction from the inside to the outside of the compression chamber. The valve arrangement comprises first and second resilient elongated plates each having first and second ends. The first ends of the first and second elongated plates are rigidly connected to the hermetic shell and the second ends are placed one on top of the other over the discharge port. The second end of the first elongated plate on the discharged port is formed with at least one opening so that the pressurized gas discharged from the discharge port hits partly on the first plate and partly on the second plate through the opening. Accordingly, the vibration of discharge valves caused by the rapid change of amount of flow of refrigerant gas produced from the discharge port can be suppressed, resulting in a quiet running of compressor.</p> |
