Abstract
A scroll compressor includes a discharge valve assembly having a valve member, a valve stop supported within the compressor shell and including an aperture therethrough and a communication member. The communication member defines a fluid passage extending into the discharge chamber from the valve stop toward the first discharge outlet in the discharge chamber and provides fluid communication between the aperture in the valve stop and a location downstream of the valve stop. A first side of the valve member abuts the valve stop when in an open position and the valve stop provides communication between the first side of the valve member and the communication member via the aperture.
Claims20
A scroll compressor comprising:
- a shell including a suction pressure region and a discharge chamber having a first discharge outlet;
- a partition coupled to said shell and separating said suction pressure region from said discharge chamber;
- a first scroll member supported within said suction pressure region of said shell and including a second discharge outlet in communication with said discharge chamber;
- a second scroll member meshingly engaged with said first scroll member;
- a drive member engaged with said second scroll member;
- and
- a discharge valve assembly including a valve member, a valve stop supported within said shell and including an aperture therethrough, and a communication member defining a fluid passage extending into said discharge chamber from said valve stop toward said first discharge outlet in said discharge chamber and providing fluid communication between said aperture in said valve stop and a location downstream of said valve stop, a first side of said valve member abutting said valve stop when in an open position and said valve stop providing communication between said first side of said valve member and said communication member via said aperture.
