    • A brush seal assembly for turbo-engines is provided for sealing off spaces on a circumferential gap which are differently acted upon by pressure, particularly between an engine stator and an engine rotor. A holding device for a bristle bundle is provided on the engine stator, from which holding device the bristle bundle is guided between circumferential webs in a sealing manner against the engine rotor and forms an axial gap in the circumferential direction with respect to one web facing the high-pressure side. The upstream one of the circumferential webs, together with the engine rotor surface, forms an axial ring gap for flow of fluid therethrough. Turbulence reducing structure is disposed upstream of the upstream web in the high pressure space and serves to reduce the turbulence in flow of air from the upstream space through the axial ring gap. This turbulence reducing structure can be in the form of a metal sponge and/or a honey comb structure.
    • 用于涡轮发动机的刷子密封组件被设置用于密封周向间隙上的空间,其不同地受到压力的作用,特别是在发动机定子和发动机转子之间。 用于刷毛束的保持装置设置在发动机定子上,保持装置使刷毛束在周向腹板之间以密封方式被引导到发动机转子上,并且相对于面向所述发动机转子的一个腹板在圆周方向上形成轴向间隙 高压侧。 周向腹板中的上游侧与发动机转子表面一起形成用于流过其中的流体的轴向环间隙。 湍流减少结构设置在高压空间中的上游腹板的上游,并且用于减少来自上游空间的空气的流动通过轴向间隙的紊流。 这种湍流减少结构可以是金属海绵和/或蜂巢结构的形式。
