A scroll compressor includes a discharge valve assembly having a valve member, a valve stop supported within the compressor shell and including an aperture there through 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.

1. 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 aid discharge chamber;a first scroll member supported within said suction pressure region of said shell and including 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; anda discharge valve assembly including a valve member, a valve stop fixed to said partition within said discharge chamber 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. 2. The compressor of claim 1, wherein said communication member includes a first end fixed to said valve stop and defining a first opening in fluid communication with said aperture in said valve stop and a second end defining a second opening generally facing said first discharge outlet. 3. The compressor of claim 2, wherein said first side of said valve member is in fluid communication with said second opening and a second side of said valve member opposite said first side is in fluid communication with a first fluid pressure from said second discharge outlet. 4. The compressor of claim 3, wherein said second opening is in fluid communication with a fluid at a second fluid pressure at said location downstream of said valve stop that is less than the first fluid pressure during compressor operation. 5. The compressor of claim 4, wherein said second opening generally faces a direction of fluid flow from said second discharge outlet to said first discharge outlet. 6. The compressor of claim 5, wherein said second fluid pressure is a localized fluid pressure at said second opening from a fluid flow past said second end of said communication member. 7. The compressor of claim 6, wherein said second fluid pressure defines a lesser pressure oscillation during compressor operation than said first fluid pressure. 8. The compressor of claim 4, wherein said second end of said communication member is positioned relative to said first discharge outlet to create a fluid flow restriction therebetween. 9. The compressor of claim 8, wherein said second opening of said communication member is spaced apart from said first discharge outlet. 10. The compressor of claim 8, wherein said second opening of said communication member is located within said first discharge outlet. 11. The compressor of claim 4, wherein said second end of said communication member is located at a maximum fluid flow velocity region of said discharge chamber. 12. The compressor of claim 1, wherein said first and second scroll members are axially displaceable relative to one another. 13. The compressor of claim 1, further comprising a bearing housing supported within said shell and supporting said first and second scroll members thereon with said first scroll member being axially displaceable relative to said bearing housing. 14. The compressor of claim 1, wherein said communication member includes a generally tubular body forming said fluid passage. 15. The compressor of claim 14, wherein said generally tubular body includes a first end fixed to said valve stop in communication with said aperture and a second end opposite said first end and extending generally parallel to a longitudinal axis of said first discharge outlet.
