摘要： A refrigeration system with two or more compressors configured to compress a flow of refrigerant with oil entrained therein. A suction flow piping arrangement is configured to supply a flow of refrigerant and oil to the two or more compressors. The suction flow piping arrangement has a suction header configured to carry the flow of refrigerant and oil, and a primary compressor supply conduit connected to the suction header. The primary compressor supply conduit supplies refrigerant and oil to a first compressor of the two or more compressors. A secondary compressor supply conduit branches off from the suction header. The secondary compressor supply conduit supplies refrigerant to a second compressor of the two or more compressors. The primary compressor supply conduit is configured to supply more oil to the first compressor than the secondary compressor supply conduit supplies to the second compressor.

摘要： A scroll compressor includes an oil separation region generally formed between the motor housing and upper bearing member. A long labyrinth channel is provided with the suction refrigerant gas flow path being redirected to facilitate coalescing of oil mist droplets out of the gas stream. An integral deflector plate can be provided on the upper bearing member to interrupt flow and facilitate coalescing of oil. Additionally, offset arrangements between motor housing outlet ports and through ports through the bearing member are provided to facilitate redirection of the refrigerant flow that can further achieve oil separation.

摘要： In its unstressed state, a suction valve is spaced from its valve seat such that the suction valve must be deformed against its inherent spring force in order to achieve seating. The spring force due to deformation provides an opening bias to the suction valve such that it opens earlier in the suction stroke and offsets the effects of adhesion due to the presence of oil between the seating surface and the valve.
