摘要： A rotary compressor having a piston provided integrally with a blade is contained in a hermetic vessel which is operated at a suction pressure of the rotary compressor and not to discharge pressure. The rotary compressor includes a compression mechanism portion having a cylinder which includes a suction port formed in a cylinder chamber, a piston which eccentrically revolves in the cylinder, a blade which is integrally formed with the piston and partitions the cylinder chamber into a high pressure chamber and a low pressure chamber, and a driving shaft for revolving the piston. The rotary compressor also includes an electric motor portion for rotating the driving shaft, a hermetic vessel which houses the compression mechanism portion and the electric motor portion and is in communication with the suction port thereby to maintain an interior of the hermetic vessel at a suction pressure atmosphere, and a discharge port formed in the cylinder chamber and in direct communication with an exterior of the hermetic vessel, whereby starting is smoothly performed, a motor having a large starting torque is not required, components such check valves can be avoided, and lubricating oils with stable viscosity can be used such that the compressor operates with environmentally-friendly refrigerants.

摘要： The invention concerns a scroll compressor which is low in noise caused by water hammering of a refrigerant gas just after a discharge valve is closed. The scroll compressor includes a discharge member (45) having a discharge port (8) opposed to a discharge port (5) of a fixed scroll (2) and a discharge valve (9) opposed to the discharge port (8) of the discharge member (45) and opened/closed depending on a difference between flow passage pressure of a refrigerant gas and pressure in a high pressure space (27) in a sealed vessel (1). At least either of the fixed scroll (2) and the discharge member (45) is formed with a muffler chamber communicated with the discharge port (5, 8) and having a diameter larger than a diameter of the discharge port (5) of the fixed scroll (2) for suppressing occurrence of an impulse wave caused by water hammering when the discharge valve (9) is closed. Noise caused by a pressure ripple of the discharge port lessens, quieting the operation of the scroll compressor.
