涡轮增压器
摘要：
本发明提供一种涡轮增压器，所述涡轮增压器防止轴的烧结，并且，防止废气的泄漏，并且，减轻结构部件的恶化，减少部件数目。根据本发明，涡轮增压器（1）配备有连接到支承在涡轮机壳体（21）的支承孔（24）中的轴构件（40）上的废气旁通阀（30），在该涡轮增压器（1）中，废气旁通阀（30）在与旁通通路（22）的开口部（23）对向的部分具有倾斜面（31），当废气旁通阀（30）被打开时，在废气（X）流入时，通过废气（X）推压倾斜面（31），推力（S1）在轴构件（40）的轴向方向上作用，经由密封构件（70），密封接触部（52）被推压到支承孔（24）的周缘部（62）上。
摘要（英）：

The present invention provides a turbocharger 1 that prevents a seizure of a shaft member, prevents a leakage of exhaust gas, suppresses deterioration of components, and reduces a number of components. The turbocharger 1 includes a waste gate valve 30 which is connected to the shaft member 40 rotatably supported by penetrating a support hole 24 of the turbine housing 20. The waste gate valve 30 includes an inclined surface 31 formed at a portion facing an opening 23 of a bypass passage 22. When the waste gate valve 30 is opened, exhaust gas X flown into the bypass passage 22 presses the inclined surface 31, thrust force S1 is applied to the shaft member 40 in a shaft direction, and a seal contact portion 52 is pressed against a peripheral edge 62 of the support hole 24 via a seal member 70.
