Abstract

Уплотнение предназначено для обеспечения непроницаемости зазора между ротором (18) и статором. Оно содержит кожух для щетины (4), размещенный на роторе (18) или статоре. На щетинки действует с одной стороны входное давление, а с другой стороны выходное давление, при этом входное давление превышает выходное давление. Щетинки (4) опираются на статор или ротор (18) со стороны уплотнения с более высоким давлением в сторону с меньшим давлением, т.е. к выходному давлению.
