Abstract
A closed compressor includes a closed case in which a plurality of compression mechanism sections are accommodated, the compression mechanism section having a cylinder including a cylinder chamber eccentrically rotatably accommodating a roller, the compression mechanism section including a blade having a leading edge to divide the cylinder chamber into two parts along a direction in which the roller rotates, the compressor including a high-pressure refrigerant introducing mechanism guiding a high-pressure refrigerant into the cylinder chamber and separating the blade from the roller, the compressor being configured to switch between a high-capacity operation in which all the compression mechanism sections perform a compression operation and a low-capacity operation in which the blade in the compression mechanism section is separated from the roller and thus prevented from performing the compression operation, the high-pressure refrigerant introducing mechanism including a high-pressure refrigerant storage section storing the high-pressure refrigerant.
