ABSTRACT:
A brush seal element (14) comprises a mounting ring (20) that carries radially inwardly directed bristles (21). A backing ring (23) attached to the mounting ring (20) is positioned alongside the bristles (21). A chamber (25) defined by the bristles (21) and the backing ring (23) is pressurised with fluid to counteract the lateral forces imposed upon the bristles (21) by a region of high fluid pressure that they are operationally adjacent. As a result of this balancing of forces the bristles (21) are free to move radially inward and outward so that their free ends (22) remain in sealing engagement with an adjacent surface.
