Abstract

Die Erfindung betrifft einen Axialverdichter (10) mit einem ringförmigen Strömungskanal (36), indem sich durch den Strömungskanal (36) erstreckende verstellbare Leitschaufeln (14) eines Leitschaufelkranzes drehgelagert gehaltert sind, wobei jede Leitschaufeln (14) zur Halterung eines Innenrings (32) an seinem Schaufelblatt (16) rotorseitig einen Zapfen (26) aufweist. Um einen verschleißarmen selbstzentrierenden Innenring (32) anzugeben, ist dieser als Spaltring mit zwei einander gegenüberliegenden Enden (44) ausgebildet und mit einem Federelement (52) zur Spreizung des Spaltsrings versehen.
