  "textContent": "A sealing arrangement (36) for sealing a leakage gap between relatively moveable parts in a flow path between a region of high pressure (A) and a region of low pressure (B). The sealing arrangement comprises an annular sealing land (52) having a radially inner surface (54) and a radially outer surface (56) projecting from one of the said moveable parts and at least two brush seal elements (40,42). The brush seal elements (40,42) comprise a mass of bristles arranged in an annular shape, one end of the bristles being fixed (48), the other being free (46). The bristles are packed together in a layer and positioned one side of a backing member (44). At least one brush seal element is provided on the radially inner surface (54) of the sealing land and at least one brush seal element is provided on the radially outer surface (56) of the sealing land (52).",
