摘要： A compressor, as well as a lightweight and strong casting for a compressor, are disclosed. The compressor, which may be a reciprocating compressor for use in compressing high-pressure refrigerants such as CO2, includes substantially reduced wall thicknesses (t) compared to prior art castings. The side walls of the compressor can be manufactured to such reduced thicknesses (t) through the use of a bridge spanning across the crankcase. This not only allows the opposing side walls to be manufactured of a thinner material, but the bottom cover removably mounted to the crankcase can be manufactured from a thinner and lighter material as well. Through the use of such a bridge, the resulting compressor is not only able to satisfy current strength requirements, but at significant weight, size and cost savings as well.
摘要翻译：公开了一种压缩机，以及用于压缩机的轻型和强力铸件。与现有技术的铸件相比，压缩机（其可以是用于压缩诸如CO 2的高压制冷剂如CO 2的往复式压缩机）包括基本上减小的壁厚（t）。压缩机的侧壁可以通过使用跨越曲轴箱的桥梁制造成这样的减小的厚度（t）。这不仅允许相对的侧壁由更薄的材料制造，而是可拆卸地安装到曲轴箱的底盖也可以由更薄和更轻的材料制造。通过使用这种桥梁，所得到的压缩机不仅能够满足当前的强度要求，而且还能够显着地提高重量，尺寸和成本。

摘要： A shaft seal assembly has a support body (222) and a seal (200). The support body extends from a first end (210) to a second end (212) and has a central passageway (214) for accommodating the shaft. The support body has a compliant axially intermediate portion (230), an axially out-board portion (228) outboard of the compliant intermediate portion, and an axially inboard portion (226) inboard of the intermediate portion. The in-board portion has an externally threaded portion (270) and a plurality of slots (290) through the externally threaded portion. The seal is carried by the out-board portion.
摘要翻译：轴密封组件具有支撑体（222）和密封件（200）。支撑体从第一端（210）延伸到第二端（212）并且具有用于容纳轴的中心通道（214）。支撑体具有柔顺的轴向中间部分（230），在柔性中间部分外侧的轴向外侧部分（228）以及中间部分内侧的轴向内侧部分（226）。板内部分具有穿过外螺纹部分的外螺纹部分（270）和多个狭槽（290）。密封件由外板部分承载。
