Patent ID: 7959421

Claim:
A compressor comprising: a shell including a suction pressure region and a discharge chamber having a discharge outlet; a compression mechanism supported within said suction pressure region of said shell and including a discharge outlet in communication with said discharge chamber; a drive member engaged with said compression mechanism to provide a pressurized fluid flow from said compression mechanism to said discharge chamber when said compression mechanism is in an operating state; and a discharge valve assembly including a valve member, a valve stop including an opening therethrough, and a communication member defining a fluid passage and extending into said discharge chamber from said valve stop toward said discharge outlet in said discharge chamber to provide fluid communication between said opening in said valve stop and a location downstream of said valve stop, said valve stop being fixed relative to said shell to limit travel of said valve member between a first position providing fluid communication between said discharge outlet in said compression mechanism and said discharge chamber and a second position restricting fluid communication therebetween, said valve member abutting said valve stop and overlying said opening when in said first position.
