ABSTRACT:
A sealing device for sealing between two static portions of a turbomachine includes a brush gasket formed by a plurality of resilient bristles which are, at least in part, held in a housing. Each bristle has a main portion and a secondary portion interconnected by a bent portion. The secondary portion has a free end ensuring leaktight contact with a surface that is to be sealed of the other static portion. The sealing device further includes a flexible washer of bent section which has a free end bearing both against the free ends of the secondary portions of the bristles of the brush gasket, and against the surface that is to be sealed so that the free ends of the secondary portions of the bristles of the brush gasket are permanently in contact with the surface that is to be sealed.
