摘要： A turbine housing assembly includes a tubular piston disposed in a bore of a turbine housing and axially slidable between a closed position and an open position for blocking a nozzle by an amount dependent on axial positioning of the piston. A bypass control member is disposed in the turbine housing and is slidable between a no-bypass position closing a bypass passage and a open bypass opening the bypass passage. The piston is structured and arranged to slide relative to the bypass control member for a part of a full stroke of the piston from the closed position toward the open position thereof, and then to engage the bypass control member and cause the bypass control member to slide together with the piston as the piston further slides toward the open position thereof such that the bypass control member is moved toward the bypass position.

摘要： A turbine assembly for a turbocharger includes a variable nozzle formed by a sliding half-collar piston. A first-stage nozzle has a plurality of first vanes supported by a first nozzle ring and extending axially therefrom. A second-stage nozzle has a second nozzle ring connected to the ends of the first vanes, and a plurality of second vanes extending axially therefrom. The piston regulates flow through the second-stage nozzle, while the first-stage nozzle remains open when the piston is fully closed. The second nozzle ring at least partially divides the first vanes from the second vanes. The half-collar piston includes recesses that receive the second vanes and only partially surround the girth of each second vane.
摘要翻译： 用于涡轮增压器的涡轮组件包括由滑动半环活塞形成的可变喷嘴。 第一级喷嘴具有由第一喷嘴环支撑并从其轴向延伸的多个第一叶片。 第二级喷嘴具有连接到第一叶片的端部的第二喷嘴环和从其轴向延伸的多个第二叶片。 当活塞完全关闭时，活塞调节通过第二级喷嘴的流量，而第一级喷嘴保持打开。 第二喷嘴环至少部分地将第一叶片与第二叶片分开。 半领活塞包括容纳第二叶片并且仅部分地围绕每个第二叶片的环的凹部。

摘要： An electrical device comprising a housing having cooling fins located in a central portion along an exterior surface of the housing and a laminated magnetic stack disposed within the housing and interfacing with an interior surface of the housing at the central portion. The cooling fins are configured alternatively higher and smaller on an inlet manifold and in opposition on an outlet manifold.
