ABSTRACT:
A rotary compressor includes a compression section disposed in a case. The compression section has a cylinder and first and second bearings fixed on both sides of the cylinder to define a compression chamber together with the cylinder. A first discharge mechanism for discharging a fluid compressed in the compression chamber into the outside of the chamber is provided at the first bearing. A second discharge mechanism for discharging a fluid compressed in the compression chamber into the outside of the chamber is provided at the second bearing. The first mechanism has a first discharge port formed in the first bearing and a first discharge valve for opening and closing the first port. The second mechanism has a second discharge port formed in the second bearing and a second discharge valve for opening and closing the second port with a different frequency from that of the first valve.
