    摘要： A turbocharger has a shaft formed of a strong material such as steel and an impeller formed of a relatively weaker material such as aluminum alloy. The impeller is mounted on the shaft by means of an internally-threaded insert, for example also of steel, interference fitted into the impeller hub. To prevent loss of the interference fit between the insert and impeller during thermal and speed excursions of the impeller during operation of the turbocharger, a constraining ring is fitted to the hub of the impeller. The ring is of a material having a lower coefficient of thermal expansion than the material of the impeller and surrounds at least a part of that axial length of the impeller which overlies the insert.

    摘要： A turbocharged internal combustion engine is provided with a diverter valve arranged to divert part of the exhaust gas flow along a conduit for introduction into a turbine region. Exhaust gases flow from the conduit, through appropriate galleries in the turbocharger casing, into internal passages formed in at least some of the stator blades. From the internal passages, the exhaust gas passes through holes positioned near the downstream ends of the convex surfaces of the stator blades. In this manner, the diverted gas is introduced into the comparatively lower pressure of the turbine region thereby enabling the diverted exhaust gas to rejoin the mainstream exhaust gas and to do useful work in driving the rotor blades while, at the same time, avoiding choking the stator blades.

    摘要： A turbocharger for an internal combustion engine is of the type having an impeller mounted on a shaft carried by a bearing supplied with lubricating oil, the shaft being located in a bore and having an oil and air seal between the bearing and the impeller hub. The seal is a floating ring seal mounted in the bore and extending radially into a circumferential recess in the impeller hub. In use, the ring seal experiences a pressure differential across it which urges it to slide axially along the bore so that it forms a sealing interface with a side face of the recess. The shaft rotates relative to the ring seal, which is therefore subject to wear against the side face of the recess. Hence, a shoulder is provided in the bore to limit excessive axial sliding of the ring seal due to wearing away of the ring seal against the side face of the recess. Sealing performance is improved and rate of wear of the ring seal is reduced by providing the ring seal with at least one inwardly-facing annular groove and providing the recess with a circumferential rib corresponding to each groove, each rib being receivable in a groove, whereby under the pressure differential a side of each groove forms a sealing interface with a side of the corresponding rib.

    摘要翻译： 用于内燃机的涡轮增压器是具有安装在由轴承供给润滑油的轴上的叶轮的类型，该轴位于孔中并且在轴承和叶轮毂之间具有油气密封。 密封件是安装在孔中的浮动环形密封件，并且径向延伸到叶轮毂中的周向凹部中。 在使用中，环形密封件经受其两端的压力差，该压力差促使其沿孔径向滑动，从而与凹槽的侧面形成密封界面。 轴相对于环形密封件旋转，因此环形密封件相对于凹部的侧面受到磨损。 因此，在孔中设置有肩部以限制环形密封件由于环形密封件相对于凹部的侧面的磨损而过度的轴向滑动。 提供密封性能并且通过将环形密封件设置在至少一个朝内的环形凹槽中并且为凹部提供与每个凹槽相对应的周向肋部来减小环形密封件的磨损率，每个肋条可容纳在凹槽中，由此 在压力差下，每个槽的一侧与相应的肋的一侧形成密封界面。
