SCROLL COMPRESSOR HAVING FIRST AND SECOND OLDHAM COUPLINGS

摘要

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.

主权项

1. A scroll compressor comprising:
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, wherein the first and second displacement directions of the first and second Oldham couplings are substantially orthogonal with respect to each other.
