    Abstract: A system may include a first compressor, a second compressor, a first heat exchanger and a second heat exchanger. The first compressor has a first inlet and a first outlet. The second compressor is a sumpless compressor and has a second inlet and a second outlet. The second compressor provides working fluid discharged from the second outlet to the first compressor. The first heat exchanger is disposed upstream of the second compressor and provides working fluid to the second compressor. The second heat exchanger is disposed upstream of the first compressor and provides working fluid to the first compressor.

    Abstract: Scroll compressor designs are provided to minimize vibration, sound, and noise transmission. The scroll compressor has a bearing housing, and orbiting and non-orbiting scroll members. The non-orbiting scroll member has a radially extending flanged portion with at least one aperture substantially aligned with the axially extending bore. At least one fastener is disposed within the aperture and the bore. A sound isolation member contacts at least one of the non-orbiting scroll member, the fastener, or the bearing housing, to reduce or eliminate noise transmission. The sound isolation member may be formed of a polymeric composite having an acoustic impedance value greater than the surrounding materials. The sound isolation member may be an annular washer, an O-ring, or a biasing member, by way of non-limiting example. In other variations, fluid passages are provided within the fastener and/or bearing housing to facilitate entry of lubricant oil to further dampen sound and noise.

    Abstract translation: 提供涡旋压缩机设计以最小化振动，声音和噪声传输。 涡旋压缩机具有轴承壳体，以及绕轨道和非轨道运动的涡旋件。 非绕动涡旋件具有径向延伸的凸缘部分，其中至少一个孔基本上与轴向延伸的孔对准。 至少一个紧固件设置在孔和孔内。 声隔离构件接触非绕动涡旋构件，紧固件或轴承壳体中的至少一个，以减少或消除噪声传播。 声音隔离构件可以由具有大于周围材料的声阻抗值的聚合复合材料形成。 声音隔离构件可以是非限制性示例的环形垫圈，O形环或偏置构件。 在其他变型中，流体通道设置在紧固件和/或轴承壳体内以便于润滑油进入以进一步抑制声音和噪声。
