Abstract:
At least one bypass opening is formed in a base of a scroll member, and communicates with at least one compression chamber. The bypass opening communicates with a passage leading to a suction pressure chamber within a compressor shell. A valve includes an element electrically powered to move between a first position at which it blocks flow of refrigerant from the bypass port to the passage leading to the suction pressure chamber, and a second position at which it allows flow of refrigerant between the bypass port and the passage leading to the suction pressure chamber. A portion of the valve, which is electrically powered, is mounted outside of the compressor shell.
