| 摘要 |
A sealing arrangement (48) for sealing a leakage gap between relatively moveable parts in a flow path between a region of high fluid pressure (D) and a region of low fluid pressure (E) comprises a sealing member (58) having an upstream surface (60), a downstream surface (62), a radially outer surface (64) and a radially inner surface (66), said sealing member (58) being in communication with a housing (54) via resilient means (56). The resilient means (56) is fixedly joined to the upstream surface (60) of the sealing member (58) such that during operation both the radial force induced on the sealing member (58) by fluid flowing axially into and circumferentially over the radially inner surface (66) and the axial force induced on the sealing member (58) because of a pressure difference across the sealing member (58) is resisted by the resilient means (56).
