摘要： A turbocharger assembly comprises a variable-vane assembly. The variable-vane assembly includes a unison ring with vane arms and/or a main-arm which adjust the setting angle of vanes. Vane arm-engaging elements and main-arm-engaging elements in the unison ring engage ends of the vane arms and the main-arm, respectively. Each vane arm-engaging element comprises an inner contact surface that engages an outer contact surface of the respective vane arm. The main-arm-engaging element comprises an inner actuation surface that engages an outer actuation surface of the main-arm. The inner contact surface and the outer contact surface and/or the inner actuation surface and the outer actuation surface may comprise conjugate curve profiles, such as involute curve profiles based on the involute of a circle. Use of conjugate curve profiles may result in rolling movement between the unison ring and vane arms and/or main arm, which may reduce friction occurring during pivoting of the vanes.

摘要： A turbocharger includes a variable-nozzle assembly that includes an insert having a tubular portion received into a stepped bore of a turbine housing and having a nozzle portion extending radially out from one end of the tubular portion, and a generally annular nozzle ring axially spaced from the nozzle portion and an array of vanes rotatably mounted to the nozzle ring. Sealing of the interface between the tubular portion of the insert and the turbine housing is provided by a sealing ring formed as a generally annular body having a U- or V-shaped cross-section oriented such that an open side of the U- or V-shaped cross-section faces in a radial direction. The U- or V-shaped cross-section defines two opposing legs, one of the legs being engaged against an end face of the tubular portion of the insert and the other leg being engaged against an upstream-facing step surface of the turbine housing bore.

摘要： A turbocharger turbine containing a separate insert affixed within the housing. The insert is of a stamped metal configuration, and forms at least a portion of inlet passageway outer wall. An axial discontinuity is machined into the inlet passageway outer wall, the axial discontinuity being characterized by a size and location to direct airflow away from the blade-gap zone over at least part of the range of flow conditions. The inlet passageway may be either larger or smaller upstream of the axial discontinuity.

摘要： A variable-nozzle assembly for a turbocharger includes a generally annular nozzle ring and an array of vanes rotatably mounted to the nozzle ring such that the vanes can be pivoted about their axes for regulating exhaust gas flow to the turbine wheel. A unison ring engages vane arms that are affixed to axles of the vanes, such that rotation of the unison ring causes the vanes to pivot between a closed position and an open position. The vanes have proximal ends that are adjacent a face of the nozzle ring. A vane sealing member is supported on the nozzle ring and has a portion disposed between the proximal ends of the vanes and the face of the nozzle ring. The unison ring includes cams that engage cam followers. Rotational movement of the unison ring causes the cam followers to be moved axially and thereby urge the vane sealing member against the proximal ends of the vanes.

摘要： A variable nozzle for a turbocharger includes a plurality of vanes rotatably mounted on a nozzle ring and disposed in a nozzle flow path defined between the nozzle ring and an opposite nozzle wall. Either or both of the faces of the nozzle ring and nozzle wall include(s) grooves extending substantially transverse to a general flow direction of the flow through the nozzle, and there are clearances between the ends of the vanes and the adjacent faces. Leakage flow through the clearance between the end of each vane and the adjacent face having the grooves must proceed across the grooves, and thus a labyrinthine flow passage is presented to the leakage flow. The labyrinthine passage has a greater resistance to flow than would be the case without the grooves. Accordingly, leakage flow is reduced, which is beneficial to turbine efficiency.
摘要翻译： 用于涡轮增压器的可变喷嘴包括可旋转地安装在喷嘴环上并且设置在限定在喷嘴环和相对的喷嘴壁之间的喷嘴流动路径中的多个叶片。 喷嘴环和喷嘴壁的一个或两个表面包括基本上横向于通过喷嘴的流动的大致流动方向延伸的槽，并且在叶片的端部和相邻的面之间存在间隙。 通过每个叶片的端部与具有凹槽的相邻面之间的间隙的泄漏流必须经过沟槽，并且因此向泄漏流提供迷宫式流路。 迷宫通道比没有凹槽的情况具有更大的阻力。 因此，泄漏流量减少，这有利于涡轮机的效率。
