摘要： A variable displacement exhaust turbocharger is provided with a plurality of nozzle vanes that are rotatably supported by a nozzle mount, a drive ring that is interlocked with an actuator and fits to a guide part of the nozzle mount, a lever plate having one end coupled to the drive ring and the other end coupled to the nozzle vane, and a variable nozzle mechanism that varies the vane angle of the nozzle vane by rotating the drive ring. A bulge suppressing portion is provided for absorbing bulging occurring on an outer peripheral surface of the guide part, the bulging being caused by the press-fitting of a nail pin into a press-fitting hole in a direction slightly toward the rotational axis with respect to the guide section and following the axial direction of the nozzle mount.

摘要： A centrifugal compressor is equipped with a resin housing, that is made in a manner such that compression efficiency is not lost and merits such as weight and cost reduction are not cancelled out. The turbo charger housing comprises a volute section, a channel formation section, and an impeller that is fixed in the center of the channel formation section to a rotating shaft. An annular shroud is disposed in a recess formed on the inner wall of the channel formation section. The annular shroud forms the outer walls of a channel and a diffuser for compressed gas. The edge of the annular shroud spaced from a partition wall, which forms a portion of a bearing housing. If the resin housing undergoes thermal deformation, the dimensions of a gap between the annular shroud and the curved profile of a blade is maintained.

摘要： A nozzle adjustment mechanism for a variable-capacity turbine has a connection between a connecting lever, for connecting a nozzle drive component driven by a actuator to a nozzle vane, and an edge of a nozzle shaft on the nozzle vane. The connection has a high degree of strength and does not experience deformation. A connecting hole of the connecting lever has a stopper surface which is flat or curved. The connecting edge of the nozzle shaft also has a stopper surface which corresponds to the stopper surface of the connecting hole. When the connecting edge of the nozzle shaft goes into the connecting hole of the connecting lever, the stopper surface of the connecting edge is brought into contact with the stopper surface of the connecting hole. After contact is made, a fixing process is applied to the connecting edge. The connector lever and the connecting edge of the nozzle shaft are thus effectively locked together in such a way that neither can rotate with respect to the other. The end of the nozzle shaft, in other words, prevents the shaft's rotation.
摘要翻译：用于可变容量涡轮机的喷嘴调节机构具有用于将由致动器驱动的喷嘴驱动部件连接到喷嘴叶片的连接杆与喷嘴叶片上的喷嘴轴的边缘之间的连接。连接强度高，不会发生变形。连接杆的连接孔具有平坦或弯曲的止动表面。喷嘴轴的连接边缘也具有与连接孔的止动面相对应的止动面。当喷嘴轴的连接边缘进入连接杆的连接孔时，连接边缘的止动面与连接孔的止动面接触。接触后，对连接边缘进行定影处理。因此，连接器杆和喷嘴轴的连接边缘以相对于另一个旋转的方式被有效地锁定在一起。换句话说，喷嘴轴的端部防止轴旋转。
