Abstract
Official abstract text for this publication.
A VTG cartridge ( 1, 2 ) of an exhaust-gas turbocharger ( 2 ), with a blade bearing ring ( 3 ), and a disk ( 4 ), which is spaced apart from the blade bearing ring ( 3 ) and together with the latter delimits a hot-gas passage ( 5 ). The disk ( 4 ) is constructed from at least two layers ( 6, 7, 6′, 7 ′), which bear loosely against one another in the assembled state of the disk ( 4 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A VTG cartridge ( 1 , 2 ) of an exhaust-gas turbocharger ( 2 ), comprising: a blade bearing ring ( 3 ), a multiplicity of guide blades adjustably mounted in the blade bearing ring ( 3 ), and a disk ( 4 ), which is spaced apart from the blade bearing ring ( 3 ), wherein the blade bearing ring ( 3 ) forms one side of a hot-gas passage ( 5 ) and the disk ( 4 ) forms the opposite side of the hot-gas passage ( 5 ), and wherein the disk ( 4 ) is constructed from at least two layers ( 6 , 7 , 6 ′, 7 ′) which are in sliding contact in an assembled state of the disk ( 4 ). 2. The VTG cartridge as claimed in claim 1 , wherein the blade bearing ring ( 3 ) is constructed from at least two layers ( 8 , 9 ), which are in sliding contact in the assembled state of the blade bearing ring ( 3 ). 3. The VTG cartridge as claimed in claim 1 , wherein the layers ( 6 , 7 , 6 ′ 7 ′, 8 , 9 ) are same material.
