1. A scroll compressor, comprising:
- 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;
a motor shaft that interfaces the Oldham ring;
wherein one of the motor shaft and the orbiting scroll has an imbalance weight portion;
wherein the imbalance weight portion;
has a weighted force profile that is about 175°
to about 185°
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.

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.

8. A scroll compressor, comprising:
-
a fixed scroll; an orbiting scroll having a base portion, wherein the orbiting scroll interfaces the fixed scroll; an Oldham ring that interfaces the orbiting scroll and has a pre-unbalanced force profile in the form of a sine wave; a motor shaft having a plate portion, wherein the motor shaft interfaces the Oldham ring; wherein the plate portion of the motor shaft and the base portion of the orbiting scroll define boundaries of an imbalance weight area; wherein the imbalance weight area includes an imbalance weight portion having a mass characterization that is equal to about 45% to about 55% of a mass of the Oldham ring; wherein the imbalance weight area converts the Oldham ring pre-unbalanced force profile to an Oldham ring post-unbalanced force profile that is in the form of a substantially flat line. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A scroll compressor, comprising:
-
a motor shaft having a plate portion; a fixed scroll that interfaces the shaft; an orbiting scroll having a base portion, wherein the orbiting scroll interfaces the fixed scroll; an Oldham ring that interfaces the orbiting scroll and has a pre-unbalanced force profile in the form of a sine wave; wherein the plate portion of the motor shaft and the base portion of the orbiting scroll define boundaries of an imbalance weight area; wherein the imbalance weight area has a mass moment profile in the form of a sine wave that is about 175°
to about 185°
opposite of the sine wave of the pre-unbalanced force profile;wherein the imbalance weight area reduces an amplitude of the sine wave of the pre-unbalanced force profile by about 45% to about 55%. - View Dependent Claims (18, 19, 20)
