Scroll compressor having first and second oldham couplings

A method of operating a scroll compressor, comprising the steps of:

• providing the scroll compressor with:
• a first fixed scroll member comprising a first fixed end plate and a first fixed spiral wrap provided on one face of the first fixed end plate,
• an orbiting scroll arrangement including at least a first orbiting scroll member comprising a first orbiting end plate and a first orbiting spiral wrap provided on one face of the first orbiting end plate, the first fixed spiral wrap and the first orbiting spiral wrap forming a plurality of first compression chambers,
• 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, the first Oldham coupling being slidable with respect to the first fixed scroll member along a first displacement direction
• a second Oldham coupling configured to prevent rotation of the orbiting scroll arrangement with respect to the first fixed scroll member, the second Oldham coupling being slidable with respect to the first fixed scroll member along a second displacement direction, the second displacement direction of the second Oldham coupling being substantially orthogonal to the first displacement direction of the first Oldham coupling, and
• displacing the orbiting scroll arrangement along an orbital movement so as to displace the first and second Oldham couplings respectively along the first and second displacement directions.
