Abstract: The seal comprises a casing made of two portions (1, 2) crimped into one another with an accurate hermetic position adjustment at interfaces (15, 6b) and a composite structure comprising inside the casing an advantageously flexible and resilient core (24) and a winding (20) of brush bristles. This structure directly extends facing internal faces (9, 10) facing each other in the casing, which compresses the same and has an arcuate shape having a slightly higher radius of curvature. The composite structure is held at an accurate position, firmly but free of constraint.
Abstract translation: 密封件包括由两个彼此压接的部分（1,2）制成的壳体，其中在界面（15,6b）处具有准确的密封位置调整和复合结构，该复合结构在壳体的内部具有有利的柔性和弹性的芯部（24）和 卷（20）的刷毛。 这种结构直接在壳体内面向彼此面对的内表面（9,10），该内表面（9,10）将其压缩并具有稍高的曲率半径的弓形。 复合结构牢固但没有限制地保持在准确的位置。
