    摘要: A vane compressor includes a cylinder, a rotor portion, vanes, and a first discharge port allowing a refrigerant in a compression chamber to be discharged therethrough. The vanes are disposed inside the rotor portion and held rotatably about the center of a cylinder inner circumferential surface, partition a space between the cylinder inner circumferential surface and the rotor portion, and form the compression chamber. A second discharge port is disposed at a location having a phase angle smaller than that at the first discharge port, being open to the cylinder inner circumferential surface, and communicating with the compression chamber. The second discharge port includes an opening portion to the compression chamber, the opening portion having a width in the circumferential direction, the width being equal to or smaller than the width of the tip of each of the vanes.

    摘要: In a vane rotary compressor, a discharge valve on a discharge flow channel communicates an operating chamber in a compression element with a discharge hole. The discharge valve is pushed from an opening portion of a discharge valve groove to an outer circumferential surface of a roller by a high-pressure refrigerant when pressure in an operating chamber is lower than the pressure of the high-pressure refrigerant. The discharge valve is pushed back into the discharge valve groove by the refrigerant pressure in the operating chamber when the pressure in the operating chamber is higher than the pressure of the high-pressure refrigerant. The discharge flow channel is closed by the outer circumferential surface of the discharge valve pushed out from the opening portion of the discharge valve groove and the outer circumferential surface of the roller, and opens when the discharge valve is pushed back into the discharge valve groove.

    摘要: There is provided a vane compressor with a plurality of vanes having a structure in which a rotor portion and a rotary shaft are unitarily formed so as to reduce bearing sliding loss of the rotary shaft and reduce gas leakage loss by narrowing a space formed between the rotor portion and the inner peripheral surface of a cylinder. In the vane compressor with the plurality of vanes according to the present invention, an angle α of a circular arc constituting the partial ring shape of each vane aligner satisfies a relationship of [ Equation   9 ]  α

    摘要: A scroll compressor has an electric motor portion, a compression mechanism portion connected to the electric motor portion, and an oil sump for lubricating oil in a sealed container and compresses a refrigerant in the compression mechanism portion. A used refrigerant is a halogenated hydrocarbon or a hydrocarbon having a carbon double bond in the composition or is a mixture containing one of the same. A sliding surface of at least one of two components constituting a sliding portion having a relation of sliding to each other in a sealed container is structured in such a way that an iron metal or an aluminum metal is not directly exposed.
