摘要： A leaf seal arrangement is provided in which within a housing there are edge portions to inter associate with non parallel chamfer edges in leaf seal elements. In such circumstances, deflection of the leaf seal elements in an outward direction or inward direction relative to a rotating shaft creates variation in a control gap X, XX between the edges and the chamfer edge. Such increase or decrease in the control gap X, XX adjusts the aerodynamic radial force that is presented to the leaf seal elements whereby those elements can be more accurately maintained at a desired leaf position for optimizing leakage while achieving better wear resistance performance.
摘要翻译：提供了一种叶片密封装置，其中在壳体内具有边缘部分以与叶片密封元件中的不平行的倒角边缘相关联。在这种情况下，叶片密封元件相对于旋转轴在向外的方向或向内方向上的偏转产生边缘和倒角边缘之间的控制间隙X，XX的变化。控制间隙X，XX的这种增加或减少调节呈现给叶片密封元件的空气动力学径向力，从而这些元件可以更准确地保持在期望的叶位置，以优化泄漏，同时实现更好的耐磨性能。
