摘要： An improved seal assembly for use with a combustion liner assembly is employed with a gas turbine engine so as to control fluid flow. The seal assembly has a bi-metal sealing member that is affixed to a first surface that is proximal to a second perpendicular surface that is not in contact with the first surface, thus providing a potential fluid flow path. Upon heating, the bi-metal sealing member “uncoils” contacting the second perpendicular surface, thus blocking the flowpath between the two surfaces. Various metals may be provided to provide predetermined sealing characteristics.

摘要翻译： 与燃气轮机组合件一起使用的改进的密封组件用于燃气涡轮发动机，以便控制流体流动。 密封组件具有双金属密封构件，该双金属密封构件固定到第一表面，该第一表面靠近不与第一表面接触的第二垂直表面，从而提供潜在的流体流动路径。 在加热时，双金属密封构件“接合”第二垂直表面，从而阻塞两个表面之间的流动路径。 可以提供各种金属以提供预定的密封特性。
