Abstract
A brush-type seal between machine components in relative motion one with respect to the other, of which at least one member rotates, in which the strands or bristles consist of composite fibers designed for good thermal conductivity in at least portions of their surface and at least the core has flexible, elastic properties. The plurality of bristles are made of combinations of glass and metal or ceramic or plastic materials and various manufacturing processes and arrangements may be used. The fibers are densely combined, massed, bundled or associated otherwise, preferably radially retained or arranged to advantage in annular brushes. The brush seals such as fluid seals are arranged in a particular application on the stator or rotor of a machine, preferably a turbomachine. This brush-type seal is applicable to seal two chambers under different pressure.
