摘要： A fluid damped, non-rotating bearing construction for a high speed rotating shaft. A sleeve surrounds the shaft on which are mounted the impeller and compressor wheels, such as in a turbocharger. The sleeve is held against rotation and against significant axial movement by a longitudinally split, hollow metal pin. The sleeve functions as both a radial bearing and a thrust bearing.

摘要： A turbocharger system. One impeller of the turbocharger is driven by exhaust gas from an internal combustion engine, the other impeller functions as a pump to either compress air or to pump air in order to convey granular material. The impeller wheels are spaced and are mounted at the ends of a common shaft. The shaft is continuously lubricated, the spent lubricant being fed to an oil sump (crankcase). The specific improvement is a pressure bleed passageway between the chamber which receives engine exhaust pressure and the oil exhaust line. The bleed allows a portion of engine exhaust to pass to the sump exhaust line and assist oil flow to the sump by virtue of a pressure differential. This action, in turn, inhibits spent oil from passing through the seals and passing into either or both impellers when oil sump (crankcase) pressure is higher than atmospheric or where there are unfavorable to gravity flow conditions existing in the oil return line. Another portion of the system bleeds air from a high pressure reservoir to the interior of the oil sump line to assist spent oil flow to the sump.
摘要翻译：涡轮增压器系统涡轮增压器的一个叶轮由来自内燃机的废气驱动，另一个叶轮用作泵来压缩空气或泵送空气以输送颗粒材料。叶轮间隔开并安装在公共轴的端部。轴连续润滑，废润滑油被送入油底壳（曲轴箱）。具体的改进是在接收发动机排气压力的腔室和排油管线之间的压力通道。排气允许发动机排气的一部分通过油底壳排气管路，并通过压力差来帮助油流入油槽。反过来，当油底壳（曲轴箱）压力高于大气压或不利于存在于回油管线中的重力流动条件时，这种动作反过来又会阻止废油通过密封件并进入任一个或两个叶轮。系统的另一部分将空气从高压储存器排出到油底壳管线的内部，以帮助废油流入贮槽。

摘要： A bearing carrier for high speed rotating machinery, such as a turbocharger, wherein lubricant is supplied under pressure and is drained by gravity. The primary feature is the forming of the bearing housing with a very large drain chamber which is obstructed only by a lubricant supply boss supporting a central housing portion in which a sleeve bearing is resiliantly mounted. Lubricant exiting from the ends of the sleeve bearing is flung circumferentially away from the rotating components and drains naturally to a lower portion of the drain chamber where it flows through a drain passage port without re-entering the rotating components or piston ring seal area. The drain port is so positioned with respect to the lubricant drain chamber and there is provided a dam around the seal area at the axial end of the lubricant drain chamber whereby the machinery may be selectively positioned with the shaft horizontal, within 10.degree. from the vertical or in intermediate positions and whereby there is effective draining of the lubricant from the machinery without flooding of the seals between the rotating components and the housing which would cause undue lubricant loss along the shaft.
