摘要： An exhaust gas turbocharger may include a shaft mounted in a bearing housing carrying a compressor wheel and a turbine wheel. The shaft may include a sealing bush arranged on the shaft in a rotationally fixed manner. The sealing bush together with a bearing housing cover may at least partially delimit an annular oil centrifuging space arranged coaxially to the sealing bush. The bearing housing cover may include a guiding nib located radially outside the sealing bush partially covering the sealing bush in axial direction. The guiding nib may be configured to guide oil separated in the oil centrifuging space onto the rotating sealing bush. The rotating sealing bush may be configured to direct the oil into the oil centrifuging space in response to centrifugal force creating an oil swirl.
摘要翻译：排气涡轮增压器可以包括安装在承载压缩机叶轮和涡轮机叶轮的轴承壳体中的轴。轴可以包括以旋转固定的方式布置在轴上的密封衬套。密封衬套与轴承座盖可以至少部分地限定与密封衬套同轴布置的环形油离心分离空间。轴承座盖可以包括位于密封衬套的径向外侧的引导尖端，其在轴向方向上部分地覆盖密封衬套。导向笔可以被构造成将在油离心空间中分离的油引导到旋转的密封衬套上。旋转的密封衬套可以被配置为响应于离心力将油引导到油离心空间中，产生油漩涡。
