摘要： A labyrinth seal impedes leakage flow though a gap between confronting static and moving parts in a turbomachine. The seal includes axially spaced and circumferentially extending sealing fins arranged in leakage flow series and projecting across the gap from at least one of the confronting parts into sealing proximity with the opposing confronting part. The fins have at least a distal portion that is curved or inclined in the upstream direction of the leakage flow to deflect the leakage flow in the upstream direction. Successive fins define chambers that accommodate recirculating vortices produced by the deflected leakage flow.
摘要翻译：迷宫密封通过涡轮机中相对的静态和运动部件之间的间隙来阻止泄漏流动。该密封件包括沿泄漏流动系列布置的轴向间隔开的并沿周向延伸的密封翅片，并从相对的部件中的至少一个凸出跨过间隙密封靠近相对的相对部件。翅片至少具有在泄漏流的上游方向上弯曲或倾斜的远侧部分，以偏转上游方向的泄漏流。连续翅片限定了容纳由偏转的泄漏流产生的再循环涡旋的腔室。

摘要： A seal for reducing a fluid flow around tips of rotating blades of a turbine includes a plurality of diaphragms disposed in succession and providing an outer support for a radial arrangement of static blades disposed alternatingly with the rotating blades in an axial direction. An outer seal has axial and radial supports. The radial support includes a ring held in position by a key and a circumferential extension of the ring. The key and the circumferential extension have a clearance so as to allow a relative radial movement between the ring and a part of a casing or the plurality of diaphragms and providing a pressure sealing face and support in the axial direction.
摘要翻译：用于减少涡轮旋转叶片尖端周围的流体流动的密封件包括多个隔离件，其连续设置并且提供用于在轴向方向上与旋转叶片交替设置的静态叶片的径向布置的外部支撑件。外部密封件具有轴向和径向支撑。径向支撑件包括通过键保持就位的环和环的周向延伸。键和周向延伸部具有间隙，以允许环与壳体或多个隔膜的一部分之间的相对径向运动，并在轴向方向上提供压力密封面和支撑。
