Patent ID: 7607902

Claim:
A closed compressor comprising a closed case, an electric motor section accommodated in the closed case, a first compression mechanism section coupled to the electric motor section, and a second compression mechanism section coupled to the electric motor section, wherein: each of the first and second compression mechanism sections comprises a cylinder comprising a cylinder chamber eccentrically rotatably accommodating a roller and a blade provided in the cylinder and having a leading end pressed and biased so as to abut against a peripheral surface of the roller to divide the cylinder chamber into two parts in a direction in which the roller rotates; the second compression mechanism is provided with a high-pressure refrigerant introducing mechanism for guiding a high-pressure refrigerant into the cylinder chamber and separating the blade from the roller in the second compression mechanism section, and the compressor is 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 second compression mechanism section is separated from the roller and thus prevented from performing the compression operation, depending on a difference in load, and the high-pressure refrigerant introducing mechanism comprises a high-pressure refrigerant storage section storing the high-pressure refrigerant.
