Patent ID: 8840384

Claim:
A scroll compressor comprising: a compressor shell having first and second scroll members, said first scroll member having a base and a generally spiral wrap extending from its base; said second scroll member having a base and a generally spiral wrap extending from its base, said generally spiral wraps of said first and second scroll members interfitting to define compression chambers; a shaft for causing said second scroll member to orbit relative to said first scroll member; at least one bypass port formed in said base of said first scroll member, and communicating with at least one of said compression chambers, and said at least one bypass port communicating with a passage leading to a suction pressure chamber within said compressor shell, and said passage being within said compressor shell; a valve, including an element electrically powered to move between a first position at which it blocks flow of refrigerant from said bypass port to said passage leading to said suction pressure chamber, and a second position at which it allows flow of refrigerant between said bypass port, and said passage leading to said suction pressure chamber and a portion of said valve which is electrically powered being mounted outside of said compressor shell and on an outer surface of said compressor shell; said compressor shell housing said suction pressure chamber, said first and second scroll members, said shaft, and a discharge pressure chamber which is downstream of said compression chambers; and said valve is mounted on said outer surface of said compressor shell, and said element moveable within said compressor shell at a location intermediate said suction and discharge pressure chambers.
