Abstract
A reverse flow tolerant brush seal arrangement for restricting the transfer of a pressurized fluid between a first and a second chamber along a moving shaft. Opposing backing plates are provided to stiffen brush bristle alignment on the moving shaft. Differential pressure between the chambers is aided by spring biasing to seat axial movement of a sliding brush seal against one of the opposing backing plates for stiffening to maintain a design clearance with a shaft being sealed.
