Abstract
An improved seal apparatus is disclosed in which the distal ends of compliant bristle elements of a conventional brush seal are disposed in a groove in adjacent structure, further being characterized by lack of contact between the bristles and structure during steady state operation of the apparatus in which the seal is installed. Sealing is afforded by the tortuosity of the leakage path. Degradation of the seal due to wear of the bristles is markedly reduced. Multiple seals in one or more constant dimension or stepped dimension grooves is also contemplated.
