Abstract: A vapor compression system includes a fluid circuit circulating a refrigerant in a closed loop. The fluid circuit has operably disposed therein, in serial order, a variable speed compressor, a first heat exchanger, an expansion device and a second heat exchanger. A first blower device is associated with the first heat exchanger. A speed of the first blower device is dependent upon a speed of the compressor. A second blower device is associated with the second heat exchanger. A speed of the second blower device is dependent upon the speed of the compressor.

Abstract: A valve assembly is mounted on a compressor mechanism and controls the passage of fluid from a compression chamber to a discharge chamber. The valve assembly includes a flexible valve member, a rigid valve retainer and a dampening element. The valve member has a first portion secured to the compressor mechanism and a second portion freely extending from the first portion. The second portion has a closed position sealingly engageable with a discharge port to prevent passage of fluid from the compression chamber to the discharge chamber. The second portion is flexible outwardly away from the discharge port thereby allowing passage of fluid from the compression chamber to the discharge chamber. The at least one dampening element is non-movingly affixed to the retainer and projects from the retainer toward the valve member. The valve member strikes the dampening element when the valve member is biased away from the discharge port.
