Abstract

A turbomachine, in particular, a compressor, having a housing and having at least one housing insert accommodated therein and having a fitting piece for the adjustment of a gap dimension between the housing and the housing insert, wherein the housing comprises, for the adjustment of the gap dimension, a horizontally adjustable guide element into which the fitting piece is inserted, is provided.

First claim

The invention claimed is:

1. A turbomachine having a housing with a radius and at least one housing insert having a radius, said radius of said housing insert received in the radius of the housing and an adjusting piece for adjusting a gap size between the housing and the at least one housing insert, wherein, in order to adjust the gap size, the housing comprises a guide element that is adjusted horizontally within a recess of the housing, and into which the adjusting piece is inserted which is connected fixedly to the at least one housing insert by a screw connection, the guide element having a horizontally running threaded bore which is aligned with a through bore in the housing, a screw or threaded rod which penetrates the through bore being screwed into the threaded bore in order to fix the gap size.

2. The turbomachine as claimed in claim 1 , wherein the adjusting piece is inserted with axial play into the guide element.

3. The turbomachine as claimed in claim 1 , wherein the guide element has an axial emptying bore.

4. The turbomachine as claimed in claim 1 , further comprising nuts secured to the threaded rod for fixing the gap size.
