发明名称 COMPRESSOR WITH CAPACITY MODULATION AND VARIABLE VOLUME RATIO
摘要 A compressor is provided and may include a shell assembly defining a suction pressure region and a discharge pressure region. A first scroll member may include a first discharge port and a first modulation port. A second scroll member may include a first variable volume ratio port. A capacity modulation valve assembly may be in fluid communication with the first modulation port and may be displaceable between open and closed positions to selectively provide communication between a first intermediate compression pocket and the suction pressure region via the first modulation port. A variable volume ratio valve assembly may be in fluid communication with the first variable volume ratio port. The variable volume ratio valve assembly may be displaceable between open and closed positions to selectively provide communication between a second intermediate compression pocket and the discharge pressure region via the first variable volume ratio port.

主权项 1. A compressor comprising: a shell assembly defining a suction pressure region and a discharge pressure region; a first scroll member disposed within said shell assembly, said first scroll member including a first end plate defining a first discharge port and a first modulation port and having a first spiral wrap extending from a first side thereof; a second scroll member disposed within said shell assembly and including a second end plate defining a first variable volume ratio port and having a second spiral wrap extending therefrom and meshingly engaged with said first spiral wrap to form a suction pocket in fluid communication with said suction pressure region, intermediate compression pockets, and a discharge pocket in fluid communication with said discharge pressure region, a first of said intermediate compression pockets being in fluid communication with said first modulation port and a second of said intermediate compression pockets being in fluid communication with said first variable volume ratio port; a capacity modulation valve assembly located within said shell assembly and in fluid communication with said first modulation port, said capacity modulation valve assembly displaceable between open and closed positions to selectively provide communication between said first intermediate compression pocket and said suction pressure region via said first modulation port; and a variable volume ratio valve assembly located within said shell assembly and in fluid communication with said first variable volume ratio port, said variable volume ratio valve assembly displaceable between open and closed positions to selectively provide communication between said second intermediate compression pocket and said discharge pressure region via said first variable volume ratio port.
