摘要： According to one embodiment, a sealed compressor is configured to suction a working fluid to a rotary compression mechanism section through a suction pipe extending into an accumulator. The sealed compressor has a relation of Aac/Acy≦4, Vac/Vcy≧20, and As/Acy≧0.12 when an inner diameter cross-sectional area of the accumulator is denoted by Aac (mm2), an inner diameter cross-sectional area of a cylinder chamber is denoted by Acy (mm2), an liquid retaining capacity to an upper end of the suction pipe inside the accumulator is denoted by Vac (cc), a total displacement volume of the rotary compression mechanism section is denoted by Vcy (cc), and a total inner diameter cross-sectional area of an extension portion inside the accumulator of the suction pipe is denoted by As (mm2).

摘要： A compression mechanism units include cylinder chambers into which a low-pressure gas is introduced, vanes contained in a vane groove, and a spring body that always causes compression operation in the cylinder chambers by providing an elastic force to a rear-end portion of one of the vanes, includes a pressure switching mechanism that switches to perform compression operation by guiding a high-pressure gas/not to perform the compression operation by guiding a low-pressure gas, is provided with a lubricating oil communication path communicatively connecting a oiling groove and a oil stagnant portion, and opposing the oiling groove to a portion other than the lubricating oil communication path when the vanes are in a top dead center position.
