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。

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.
摘要翻译：用于涡轮增压器的可变喷嘴组件包括大致环形的喷嘴环和可旋转地安装到喷嘴环的叶片阵列，使得叶片可围绕它们的轴线枢转以调节到涡轮机叶轮的排气流。协调环接合固定到叶片的轴的叶片臂，使得协调环的旋转导致叶片在关闭位置和打开位置之间枢转。叶片具有邻近喷嘴环的表面的近端。叶片密封构件支撑在喷嘴环上，并且具有设置在叶片的近端和喷嘴环的表面之间的部分。协调环包括接合凸轮从动件的凸轮。协调环的旋转运动导致凸轮从动件轴向移动，从而推动叶片密封构件抵靠叶片的近端。
