摘要： An object is to inhibit a refrigerant leakage and enhance a performance of a compressor. The compressor comprises a driving element stored in a sealed container of the compressor, and a compression element driven by a rotary shaft of the driving element. This compression element comprises a cylinder in which a compression space is constituted; a suction port and a discharge port which communicate with the compression space in the cylinder; a compression member whose one surface crossing an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is rotatably disposed in the cylinder and which compresses a fluid (refrigerant) sucked from the suction port to discharge the fluid via the discharge port; and a vane which is disposed between the suction port and the discharge port to abut on an upper surface as one surface of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber, and one surface of the compression member is disposed on a side opposite to the driving element.

摘要： An object of the present invention is to promote oil separation in a sealed container, thereby decreasing the amount of oil discharged to the outside of a compressor. The compressor comprises discharge hole provided at position facing the end surface of a rotor and through which a compressed refrigerant from first and second rotary compression elements is discharged into the sealed container; and a refrigerant flow path which is extended from a space surrounded with a coil end of a stator projecting from the end surface of the rotor to a rotary compression mechanism side to a space of an air gap between the rotor and the stator, to guide the compressed refrigerant discharged through the discharge hole to an electromotive element opposite to the rotary compression mechanism side. The outlet of this refrigerant flow path opposite to the rotary compression mechanism side faces the inner wall surface of the sealed container, and the volume of a space between the inner wall surface of the sealed container and the electromotive element is 1.5 times or more and 15 times or less that of a space between the rotary compression element and the electromotive element.

摘要： A compressor includes two rotary compressing elements in a vessel. One of the compressing elements operates while the other element is in a non-operating mode. In the non-operating mode, inflow of refrigerant gas into the cylinder of the rotary compressing element is blocked and a suction side pressure of the rotary compressing element is applied as a back pressure to a vane. A compressing system includes the compressor and a controller and operates in first and second operation modes. In the first operation mode, refrigerant gas flows into a cylinder and an intermediate pressure, a result of flow of the refrigerant gas from between a vane and a guide groove into a back pressure portion, between a suction side pressure and a discharge side pressure, is applied as a back pressure to bias the vane against a roller.
