Abstract

Die vorliegende Erfindung betrifft einen aus einzelnen Dichtsegmenten zusammengesetzten Dichtungsring für Strömungsmaschinen, wobei zwischen den einzelnen Dichtsegmenten Federn angebracht sind und an der Teilfuge der Strömungsmaschine Sicherungselemente zum Halten der Dichtsegmente vorgesehen sind. Um ein sicheres Schliessen der Dichtungselemente auch an der Teilfuge zu gewährleisten, sind die Dichtsegmente an der Teilfuge formschlüssig miteinander verbunden.
