FIELD: machine engineering.
SUBSTANCE: invention relates to a gasket comprising a body formed of two portions (1, 2) pressed into one another with precise and airtight fitting in position on the boundary surfaces (15, 6b), and a composite structure comprising inside the shell is preferably flexible and a resilient core (24) and winding (20) of the bristles of the brush. This structure is situated directly opposite the inner sides (9, 10) located opposite each other in the housing, which compress it and have an arc shape with a radius of curvature slightly larger than that.
