  • Patent number: 7736138
    Abstract: A compressor comprises: a cylinder with a compression space; a suction port and a discharge port which communicate with the compression space in the cylinder; a support member which closes an opening of the cylinder; a rotary shaft which is rotatably supported on the support member; 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 rotated and compresses a fluid to discharge the fluid via the discharge port; and a vane which is disposed between a suction port and the discharge port, abuts on one surface of the compression member and partitions the compression space in the cylinder into high and low pressure chambers.
    Type: Grant

  • Patent number: 7581937
    Abstract: A compressor having a sealed container; 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 support member which closes an opening of the cylinder; a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member; 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; a vane which is disposed between the suction port and the discharge port to abut on one surface side of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber. A pressure of the compression member on the other surface side of the compression member is set to a value which is lower than tat of a pressure in the sealed container.

  • Patent number: 7481635
    Abstract: A compressor having a compression element with 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 support member which closes an opening on the cylinder and a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member. A compression member, whose one surface crosses an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and is disposed in the cylinder to be rotated by the rotary shaft, compresses a fluid sucked from the suction port to discharge the fluid via the discharge port. A vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member partitions the compression space in the cylinder into a low pressure chamber and high pressure chamber.

  • Patent number: 7458461
    Abstract: A compressor packaging apparatus for fixing plural compressors each of which has dish-shaped end caps at both the upper and lower end portions of a cylindrical compressor body, including an upper plate and a lower plate between which the compressors are sandwiched and fixed, the lower plate being equipped with a plurality of stepped fitting portions in which the lower end caps of the compressors are fitted, and first paper pipes fitted to the stepped fitting portions. Furthermore, an intermediate plate having plural insertion holes in which the compressor bodies are inserted is provided, and second paper pipes fitted to the end caps at the upper portions of the compressors and third paper pipes may be provided between the upper plate and the intermediate plate.
