Abstract

Уплотнительное устройство, которое расположено между двумя статическими частями (2, 4) турбомашины, содержит щеточное уплотнение (10), образованное уплотнительными эластичными волокнами, которые по меньшей мере частично находятся в пазу (8). У каждого волокна есть основной участок (10а) и второй участок (10b), которые соединены выгнутым участком (10с), причем второй участок (10b) волокна имеет свободный конец (14), который обеспечивает плотное соприкасание с поверхностью, которая уплотняется (16), второй статической части (4). Уплотнительное устройство дополнительно содержит выгнутую в сечении гибкую прокладку (18), свободный конец (20) которой упирается одновременно в свободные концы вторых участков (10b) волокон щеточного уплотнения (10) и в поверхность, которая уплотняется, (16). В результате свободные концы (14) вторых участков (10b) волокон щеточного уплотнения (10) постоянно соприкасаются с поверхностью, которая уплотняется, (16).
