摘要： A turbocharger having a by-pass system for selectively by-passing exhaust gases from the turbine rotor. The by-pass arrangement includes a housing portion having a by-pass passage which preferably extends from the exhaust inlet to the exhaust outlet. There is a port from the exhaust inlet into the by-pass passage which is selectively controlled by a pivoted valve. The turbocharger with the by-pass arrangement may be utilized with a conventional vehicle exhaust system of the type having a catalytic convertor and if so desired, a major portion of the by-pass gases may also by-pass the catalytic convertor. A control device disposed remote from the turbocharger permits the use of relatively inexpensive control elements.
摘要翻译：一种具有旁通系统的涡轮增压器，用于选择性地旁路来自涡轮转子的废气。旁通布置包括具有旁路通道的壳体部分，其优选地从排气入口延伸到排气出口。从排气入口到旁通通道有一个端口，旁通通道由枢转阀门选择性地控制。具有旁通装置的涡轮增压器可以与具有催化转化器的常规车辆排气系统一起使用，如果需要，旁通气体的主要部分也可以绕过催化转化器。远离涡轮增压器设置的控制装置允许使用相对便宜的控制元件。

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.
摘要翻译：用于高速旋转机械的轴承载体，例如涡轮增压器，其中在压力下供应润滑剂并通过重力排出。主要特征是形成具有非常大的排放室的轴承箱，该排水室仅由支撑中心壳体部分的润滑剂供给凸起而阻塞，其中套筒轴承被牢固地安装在其中。从套筒轴承的端部排出的润滑剂沿圆周方向远离旋转部件而被排出，并且自然地排放到排水室的下部，在其下方流过排水通道口，而不会重新进入旋转部件或活塞环密封区域。排水口相对于润滑剂排放室定位，并且在润滑剂排放室的轴向端处设置有围绕密封区域的坝，由此机械可以选择性地定位在水平轴上，与垂直方向的10° 或在中间位置，并且由此可以有效地从机械中排出润滑剂，而不会在旋转部件和壳体之间的密封件溢流，这将导致沿着轴的不适当的润滑剂损失。

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 centrifugal compressor is described herein which comprises a bearing housing, an impeller rotatably mounted to the housing, and an integral compressor cover mounted upon the housing and including an impeller chamber within which the impeller is received. The compressor cover includes a wall portion which defines the impeller chamber and further includes a scroll portion defining a volute passageway surrounding the impeller chamber. The scroll portion includes a mounting flange having a cylindrical pilot surface secured to a mounting flange on the bearing housing. The cover further includes a ring-like flange extending outwardly from one end of the wall portion and forming with the mounting flanges of the scroll and bearing housing an annular, diffuser passageway communicating with the volute passageway and the impeller chamber. The diffuser flange extends radially outward of the pilot surface of the scroll, only the portion of the diffuser flange which is radially inward of the pilot surface being machined. The diffuser flange includes a negative, axial offset at a location radially at or inward of the pilot surface and continuing for the outward extent of the flange.
