    • A device for assisting with the radial distribution of a fluid from a rotating shaft having an axially oriented feed passage opening through an entry, end portion of the shaft and a plurality of discharge ports (P.sub.1 -P.sub.4) spaced axially, and circumferentially, about the shaft to effect communication between the feed passage and the exterior of the shaft. The device is insertably received within the entry end portion of the feed passage. A plug portion is provided to retain flange by being utilized to determine the extend to which the plug portion may be insertably received within the feed passage. An annular constriction is presented from the device, and the constriction is adapted to be located interiorly of, and axially inwardly from, the entry end portion of the feed passage. A flared portion tapers conically outwardly from the constriction and extends inwardly along the feed passage for a predetermined distance to underlie selected discharge ports (P.sub.3 -P.sub.4). The flared portion extends from the constriction to a terminal end portion. A spacer flange extends radially outwardly from the terminal end portion to engage the interior wall of the feed passage. The spacer flange is circumferentially discontinuous to provide at least one back-flow aperture along the exterior of the terminal end portion.
    • 一种用于辅助来自旋转轴的流体的径向分布的装置,其具有通过入口,所述轴的端部的轴向定向的供给通道开口,以及沿轴向间隔并围绕所述轴线定位的多个排出口(P1-P4) 轴,以实现进给通道和轴的外部之间的连通。 该装置被可插入地容纳在进料通道的入口端部分内。 插头部分被设置成通过用于确定插头部分可插入地容纳在进给通道内的延伸部来保持凸缘。 从装置呈现环形收缩,并且收缩部适于位于进给通道的进入端部的内部并且轴向向内。 喇叭形部分从收缩部向外锥形地向外渐缩并且沿着进给通道向内延伸预定距离以位于所选择的排出口(P3-P4)的下方。 扩口部从收缩部延伸到终端部。 间隔件凸缘从终端部分径向向外延伸以接合进料通道的内壁。 间隔件凸缘沿周向不连续,以沿着终端部分的外部提供至少一个回流孔。

    • A lubricating device, especially for use with a hermetic motor compressor unit, having a vertical shaft extending downwardly into a lubricant sump. The lubricating device comprises a pick-up tube having a larger diameter upper cylindrical portion open at the upper end thereof and adapted for being fitted into a central bore in the shaft, a smaller diameter lower cylindrical portion adapted to be immersed in fluid in the sump, a tapering transition region connecting the upper and lower cylindrical portions, an inlet port extending axially into the lower end of the lower portion, and the pair of diametrally opposite ribs on the lower cylindrical portion comprising ridges on the inner surface and corresponding hollows on the outer surface thereof.
    • 一种特别用于封闭式电动机压缩机单元的润滑装置,具有向下延伸到润滑油槽中的垂直轴。 润滑装置包括拾取管,其具有在其上端开口的较大直径的上圆柱形部分,并且适于装配到轴中的中心孔中,较小直径的下圆柱形部分适于浸入流体中的贮槽 连接上部和下部圆柱形部分的锥形过渡区域,轴向延伸到下部部分的下端的入口端口,下部圆柱形部分上的一对直径相对的肋条包括内表面上的脊和在其上的相应的中空部分 其外表面。

    • A lubricating oil supply apparatus of a reciprocating compressor comprises: an oil cylinder penetratingly-formed at a lower side of a frame, for supporting a compression unit which compresses a fluid; an oil piston reciprocatingly-inserted into the oil cylinder and reciprocated by a vibration of the compressor, for pumping lubricating oil; a spring connected to a rear side of the oil piston and providing an elastic force to the oil piston; and a valve assembly disposed at a front side of the frame, for opening and closing a passage of lubricating oil supplied to a sliding part of the compressing unit. A dead volume existing at the oil supply apparatus is reduced thereby to smoothly supply lubricating oil even at the time of an initial driving that requires less pumping amount, thereby enhancing a lubricating performance.
    • 往复式压缩机的润滑油供给装置包括:贯通地形成在框架的下侧的油缸,用于支撑压缩流体的压缩单元; 一个油压活塞往往插入到油缸中并通过压缩机的振动往复运动,用于泵送润滑油; 连接到油活塞的后侧并向油活塞提供弹性力的弹簧; 以及阀组件,其设置在所述框架的前侧,用于打开和关闭供应到所述压缩单元的滑动部分的润滑油的通道。 在供油装置中存在的死体积减少,从而即使在需要较少抽吸量的初始驱动时平滑地供给润滑油,从而提高润滑性能。
