    摘要： A scroll compressor includes a fixed scroll and an orbiting scroll which define therebetween a plurality of compression chambers for compressing fluid introduced via a suction port. The orbiting scroll has a base plate and a shaft portion extending from the base plate toward a crankshaft rotatably supported by a support member. A seal member is disposed between the base plate and the support member to define an inner region and an outer region. The inner region surrounds the shaft portion, while the outer region includes therein a rotation preventing member interposed between the base plate of the orbiting scroll and the support member. The inner region communicates with the outer region via an oil-feed passage formed through the orbiting scroll. The oil-feed passage includes therein a restrictor and opens in the neighborhood of an upper sliding portion between the rotation preventing member and the support member. Thus, lubricating oil supplied to the inner region is fed to the neighborhood of the upper sliding portion via the oil-feed passage for lubrication thereof. The lubricating oil collects downward due to the gravity to achieve lubrication of a lower sliding portion between the rotation preventing member and the support member.

    摘要翻译： 涡旋压缩机包括固定涡旋件和绕动涡旋件，其在其间限定多个用于压缩通过吸入口引入的流体的压缩室。 绕动涡盘具有基板和从基板向由支撑构件可旋转地支撑的曲轴延伸的轴部。 密封构件设置在基板和支撑构件之间以限定内部区域和外部区域。 内部区域围绕轴部，而外部区域包括设置在绕动涡盘的基板和支撑构件之间的防旋转构件。 内部区域经由绕动涡盘形成的供油路与外部区域连通。 供油通道包括限流器，并且在旋转阻止构件和支撑构件之间的上部滑动部分附近开口。 因此，供给到内部区域的润滑油经由供油通路被供给到上部滑动部附近，以进行润滑。 润滑油由于重力而向下收集，以实现旋转防止构件和支撑构件之间的下滑动部分的润滑。

    摘要： A scroll compressor having an extended life due to the support structure for the orbiting scroll, even when using a chlorine-free substitution refrigerant. The support structure includes an Oldham ring for supporting an orbiting scroll so as to allow the orbiting scroll more orbiting motion without rotating about a fixing scroll. The Oldham ring is formed of a different material from both a fixing member and the orbiting scroll. Hence, if a boundary lubrication state occurs in mutually sliding parts, only sliding between different materials occurs, and mutual adhesion in the portion of the boundary lubrication state is avoided. As a result, the shortening of the life due to the wearing of the support structure of the orbiting scroll is prevented.

    摘要： An orbiting scroll is engaged to and moved orbitally in relation to a fixed scroll at variable speeds. An offset surface is provided in at least one of the wraps of the fixed scroll and/or the orbiting scroll, by which a space S is created in one of the compression chambers formed between the fixed scroll and the orbiting scroll, which is thereby unsealed and opened to the inlet port side. The offset surface has a length from a position in the spiral length which satisfies the required compression ratio of one of the compression chambers in a low speed operation to the end of the spiral. An injection port is positioned such as to open to an unsealed area of this compression chamber, and gas injection shutoff and resumption is controlled through this injection port as appropriate to the situation.

    摘要： When sliding elements, slide bushings, vanes and Oldham rings employed in various types of refrigeration compressors and other applications meet the following conditions, they resist sticking to aluminum-base components, resist depletion of the oil film on slide faces, and exhibit excellent wear resistance. Firstly, the elements must comprise an iron-base sinter having closed cells on at least the slide face. Secondly, in order for the oil film to be maintained on the slide face by the closed cells and to enhance lubricating properties, the proportion of closed cells having circular-equivalent diameter of 10 &mgr;m or less, i.e. the number of ≦10 &mgr;m cells/total number of cells, must equal 85% or more, and the opening area of the closed cells on the slide face must equal 5% or less. Finally, the sliding element density must be 7.3 g/cm3 or higher.
