BRUSH-TYPE CIRCULAR SEAL

摘要

The seal comprises a housing made up of two portions (1, 2) clamped together as a close and fluid tight fit at interfaces (15, 6b) and a composite structure comprising, inside the housing, a core (24) that is advantageously soft and elastic and a winding (20) of brush bristles. This structure extends directly facing the opposing internal faces (9, 10) of the housing, which compresses them and has an arched shape of slightly larger radius of curvature. The composite structure is kept in a precise position firmly but without stress.
