A foam control device includes a first member coupled to an oil reservoir of a compressor and a second member to prevent foam from flowing into an interior section of the compressor. when a shaft of the compressor rotates. The second member controls a position of the first member based on at least one condition which, for example, may include an amount of oil in the reservoir, an environmental condition, or the type of oil or refrigerant used. According to one embodiment, the first member includes a plate containing one or more apertures that allow oil, suctioned from the reservoir, to pass back into the reservoir when the compressor shaft rotates.

What is claimed is: 1. A foam control device for a compressor, comprising: a first member coupled to an oil reservoir; and a second member coupled to the first member, at least the first member provided to prevent foam from flowing into an interior section of the compressor when a shaft of the compressor rotates, the second member controlling a position of the first member based on at least one condition, wherein the second member is coupled between the first member and a sub-frame member and wherein the sub-frame member is coupled to and located within the reservoir. 2. The foam control device of claim 1, wherein the at least one condition is an amount of oil in the reservoir. 3. The foam control device of claim 1, wherein the at least one condition is an environmental condition. 4. The foam control device of claim 1, wherein the at least one condition is a type of oil or refrigerant in the compressor. 5. The foam control device of claim 1, wherein the first member includes a plate having one or more apertures to allow oil suctioned from the reservoir to pass back into the reservoir. 6. The foam control device of claim 5, wherein said one or more apertures are arcuate in shape. 7. The foam control device of claim 6, wherein the one or more arcuate apertures are concentrically disposed at one or more predetermined angles. 8. The foam control device of claim 6, wherein a first arcuate aperture is larger than a second arcuate aperture aligned at a predetermined angle relative to a center of the first member. 9. The foam control device of claim 1, wherein the second member includes a spring. 10. The foam control device of claim 1, wherein the second member is formed from a stack of sheets coupled between two arms of the sub-frame member proximate the reservoir. 11. The foam control device of claim 1, wherein the first member is coupled to the shaft. 12. The foam control device of claim 1, wherein the compressor is a scroll compressor. 13. The foam control device of claim 1, wherein the sub-frame member includes a plurality of arm members symmetrically oriented relative to and projecting radially from the shaft, and wherein a plurality of second members are coupled between the first member and respective ones of the arm members within the reservoir. 14. The foam control device of claim 13, wherein each of the second members includes a spring. 15. The foam control device of claim 14, wherein a first end of the spring contacts a first protrusion extending from a surface of the first member and a second end of the spring is contacts a second protrusion extending from a surface of a corresponding one of the arm members. 16. The foam control device of claim 15, wherein the spring is held in place between the first and second protrusions solely as a result of compression forces generated by the spring. 17. The foam control device of claim 16, wherein the first end of the spring surrounds the first protrusion and the second end of the spring surrounds the second protrusion. 18. The foam control device of claim 14, wherein a compression force generated by the spring controls a distance between the first member and a respective one of the arm members. 19. The foam control device of claim 13, wherein each arm member has a distal end that includes an upper member spaced a predetermined distance from a lower member, and wherein the second member is located between the upper member and the first member. 20. The foam control device of claim 1, wherein the second member controls a separation distance between the first member and the frame member within the reservoir. 21. The foam control device of claim 1, wherein a separation distance between the first member and oil in the reservoir is varied by at least the second member based on the at least one condition. 22. The foam control device of claim 21, wherein the separation distance between the first member and the oil in the reservoir is varied by the second member based on a type of the oil in the reservoir. 23. The foam control device of claim 21, wherein the separation distance between the first member and the oil in the reservoir is varied by the second member based on an amount of the oil.
