    摘要： A brush seal device for sealing a high pressure area from a low pressure area. The brush seal device comprises an annular retaining plate having a first side facing the high pressure area and a second side opposite the first side, and an annular back plate having a first side facing the low pressure area and a second side opposite the first side, the second side of the back plate having an outer peripheral portion and an inner peripheral portion. A plurality of bristles are between the second side of the retaining plate and the outer peripheral portion of the second side of the back plate such that they extend inwardly from the outer peripheral portion of the second side of the back plate. The inner peripheral portion of the second side of the back plate has a recessed surface formed therein to inhibit the plurality of bristles from contacting the inner peripheral portion of the second side of the back plate.
