Patent ID: 7568897

Claim:
A compressor comprising: a housing including a partition separating a suction pressure region operating at a suction pressure from a discharge pressure region operating at a discharge pressure and defining a housing discharge passage in communication with the discharge pressure region; a compression mechanism supported within said housing and including first and second scroll members meshingly engaged with one another to form a series of compression pockets, said first scroll member including a scroll discharge passage in communication with said housing discharge passage; and a seal assembly that is sealingly engaged with said partition and said compression mechanism and defining a sealed discharge region from said scroll discharge passage to said housing discharge passage, said seal assembly and said compression mechanism defining a chamber in communication with one of said compression pockets, said seal assembly including a seal member engaged with said compression mechanism and including a leg having an opening therein, said leg being displaceable between a first position and a second position different than the first position during compressor operation, said leg isolating said chamber from said sealed discharge region when in the first position and said leg providing communication between said chamber and said sealed discharge region through said opening when in the second position.
