Definitions

  • Patent document 1 discloses a rotary compressor which reliably prevents a vane from jumping.
  • This rotary compressor includes a cylinder whose both end openings are closed, a piston which rotates in the cylinder, a vane which forms a compression space together with the piston and the cylinder and which partitions the space into a high pressure side and a low pressure side, and connecting means for swingably connecting the piston and the vane to each other.
  • the rotary compressor 200 includes a drive shaft 201, the upper piston 2021, the lower piston 2022, the upper cylinder 2031, the lower cylinder 2032, an upper bearing 204, a lower bearing 205, upper and lower vanes, the upper intake hole 2071a, the lower intake hole 2072a and a partition plate 221.
  • Upper and lower compression elements are configured in the axial direction.
  • the partition plate 221 is provided between the upper and lower compression elements.
  • An upper bearing 204 and the lower bearing 205 support the drive shaft 201.
  • the upper intake hole 2071a is provided in the upper bearing 204
  • the lower intake hole 2072a is provided in the lower bearing 205.
  • a rotary compressor 300 of the third embodiment is different from the rotary compressor 200 of the second embodiment at least in that a partition plate 321 is provided with an intake hole 307a instead of an upper bearing 304 and a lower bearing 305.
  • the rotary compressor 100 of one cylinder and the rotary compressors 200 and 300 of two cylinders are described as one examples of the rotary compressor. It is only necessary that the rotary compressor compresses gas. Therefore, the rotary compressor is not limited to the rotary compressor 100 of one cylinder or the rotary compressors 200 and 300 of two cylinders. However, if the rotary compressor 100 of one cylinder or the rotary compressors 200 and 300 of two cylinders are used, there are merits that balance between costs, efficiency and reliability is kept and volume production can be made. As the rotary compressor, a two-stage compressor may be used.
  • one cylinder may include a plurality of vanes and compression chambers. If this is used, torque variation can be reduced by carrying out the compression action which is substantially the same as that of the two-cylinder type in the configuration of the rotary compressor 100 of the one cylinder, and a pressure difference can be reduced if the two-stage compression configuration is employed. Therefore it is possible to realize a rotary compressor capable of carrying out low vibration and high pressure ratio operation with the small number of parts.
  • vane 106 having the engaging portion 106a which is swingably fitted into and connected to the engaging groove 102a formed in the piston 102 was described as one example of the vane.
  • the vane partitions the intake chamber and the compression chamber from each other, the vane is always operated integrally with the piston, and a spring is unnecessary on the back surface of the vane. Therefore, the vane is not limited to the vane 106 including the engaging portion 106a which is swingably fitted into and connected to the engaging groove 102a formed in the piston 102.
