Abstract
A scroll compressor includes a fixed scroll; an orbiting scroll that interfaces the fixed scroll; an Oldham ring that interfaces the orbiting scroll and has a pre-unbalanced force profile; and a motor shaft that interfaces the Oldham ring. The Oldham ring pre-unbalanced force profile is in the form of a sine wave. One of the shaft and the orbiting scroll has an imbalance weight portion; wherein the imbalance weight portion provides a weighted force profile that is 180° opposite of the pre-unbalanced force profile of the Oldham ring and produces in the Oldham ring a post-unbalanced force profile that is substantially a flat line.
