Abstract
A multi-plane annular brush seal includes a front plate, a back plate, and a plurality of bristles. Each of the plurality of bristles has a first lengthwise portion extending from the base end, a second lengthwise portion, and a third lengthwise portion. The front plate and back plate are configured to maintain the bristle first lengthwise portions substantially parallel to a first plane, the second lengthwise portion of the bristles through a transition region, and the bristle third lengthwise portions substantially parallel to a second plane. The first plane is skewed from the second plane by an obtuse angle. At least some of the bristle second lengthwise portions are maintained in contact with the front plate through the transition region and at least some of the bristle second lengthwise portions are maintained in contact with the back plate through the transition region.
