Definitions

  • the present invention relates to a co-rotating scroll compressor.
  • the co-rotating scroll compressor includes a driving-side scroll and a driven-side scroll that rotates together with and in synchronization with the driving-side scroll.
  • the co-rotating scroll compressor rotates the driving shaft and the driven shaft in the same direction at the same angular velocity by offsetting a driven shaft that supports the rotation of the driven-side scroll from a driving shaft that rotates the driving-side scroll by the turning radius.
  • the present invention has been made in view of the situation as above, and an object thereof is to provide a co-rotating scroll compressor that can be downsized.
  • a co-rotating scroll compressor of the present invention employs the following solutions.
