Scroll machine with seal

A compressor comprising:

• a housing including a suction pressure region operating at a suction pressure and a first discharge passage in communication with a discharge pressure region operating at a discharge pressure;
• 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 second discharge passage in communication with said first discharge passage;
• and
• a seal assembly that is sealingly engaged with said housing and said compression mechanism that provides sealed communication between said first and second discharge passages, 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 a notch in a first end thereof that is in communication with said discharge pressure region and isolated from said chamber when said leg is in a first position, said leg being displaceable to a second position where said notch is in communication with said discharge pressure region and said chamber.

A compressor comprising:

• a housing including a first pressure region operating at a first pressure and a first discharge passage in communication with a discharge pressure region operating at a discharge pressure;
• a compression mechanism supported within said housing and including non-orbiting and orbiting scroll members meshingly engaged with one another to form a series of compression pockets, said non-orbiting scroll member including a second discharge passage in communication with said first discharge passage;
• and
• a seal assembly that is sealingly engaged with said housing and said non-orbiting scroll member that provides sealed communication between said first and second discharge passages, said seal assembly including a seal member engaged with said non-orbiting scroll member and including a leg having an opening therein, said leg providing sealed communication between said first and second discharge passages when in a first position and said leg providing communication between said first pressure region and said discharge pressure region through said opening when in a second position different than the first position.
