  • Patent number: 10731650
    Abstract: A rotary compressor includes: a shell defining an internal space; a driving motor arranged in the internal space of the shell; and a compression mechanism unit to receive power of the driving motor and compress refrigerant, wherein the compression mechanism unit includes: a cylinder defining a chamber in which the refrigerant is compressed; a rotary shaft connected to the driving motor; a roller located in the chamber and connected to the rotary shaft to compress the refrigerant in the chamber while being rotated; a bearing coupled to the cylinder and having a discharge port through which the refrigerant compressed in the chamber passes; a muffler coupled to the bearing and into which the refrigerant passing through the discharge port is introduced; and a noise reducing unit fixed to the muffler to define a noise reducing chamber together with the muffler.
