Abstract

Bei einem Verdichter mit axial geteiltem Gehäuse, bestehend aus mehreren Gehäusehälften (21a, 21b), sind die Leitschaufeln (1) mit ihren Füssen (3) in Umfangsnuten (10) befestigt. Ueber den Umfang verteilt sind im Nutgrund der Umfangsnut (10) verankerte Bolzen (8) eingebracht. Diese Bozen (8) ragen vorzugsweise radial in die Umfangsnut (10) hinein und unterteilen die Leitschaufeln (1) in Gruppen (A4, A5) und an der Trennebene (20) des Gehäuses (21a, 21b) liegende Abschluss-Gruppen (A6, A7).
