Abstract
This scroll compressor includes a first fixed scroll member, an orbiting scroll arrangement including a first orbiting scroll member, a first Oldham coupling provided between the first orbiting scroll member and the first fixed scroll member and configured to prevent rotation of the first orbiting scroll member with respect to the first fixed scroll member, a fixed element opposite to the first fixed scroll member with respect to the orbiting scroll arrangement, and a second Oldham coupling provided between the orbiting scroll arrangement and the fixed element and configured to prevent rotation of the orbiting scroll arrangement with respect to the fixed element. The first Oldham coupling is slidable with respect to the first fixed scroll member along a first displacement direction, and the second Oldham coupling is slidable with respect to the fixed element along a second displacement direction transverse to the first displacement direction.
