Abstract
Official abstract text for this publication.
An exhaust-gas turbocharger ( 1 ) having a compressor ( 2 ); a turbine ( 3 ); and a bearing housing ( 4 ) which has a lubricant device ( 5 ) for shaft bearings ( 6, 7 ), which lubricant device can be connected via a lubricant feed line ( 8 ) to an engine lubricant circuit. A lubricant storage vessel ( 9 ) is connected between the lubricant feed line ( 8 ) and the lubricant device ( 5 ) of the bearing housing ( 4 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. An exhaust-gas turbocharger ( 1 ), having a compressor ( 2 ); a turbine ( 3 ); and a bearing housing ( 4 ) which has a lubricant device ( 5 ) for shaft bearings ( 6 , 7 ), which lubricant device is connected via a lubricant feed line ( 8 ) to an engine lubricant circuit, wherein a lubricant storage vessel ( 9 ) is connected between the lubricant feed line ( 8 ) and the lubricant device ( 5 ) of the bearing housing ( 4 ) such that when a pressure prevails in the lubricant feed line, the lubricant is forced out of the lubricant storage vessel into the bearing housing. 2. The exhaust-gas turbocharger as claimed in claim 1 , wherein the lubricant storage vessel ( 9 ) is mounted on the bearing housing ( 4 ). 3. The exhaust-gas turbocharger as claimed in claim 1 , wherein the lubricant storage vessel ( 9 ) has a feed connector ( 10 ) which is screwed into the bearing housing ( 4 ). 4. The exhaust-gas turbocharger as claimed in claim 1 , wherein the lubricant storage vessel has a line port ( 12 ) which is connected to the lubricant feed line ( 8 ). 5. An exhaust-gas turbocharger ( 1 ), having a compressor ( 2 ); a turbine ( 3 ); and a bearing housing ( 4 ) which has a lubricant device ( 5 ) for shaft bearings ( 6 , 7 ), which lubricant device is connected via a lubricant feed line ( 8 ) to an engine lubricant circuit, wherein a lubricant storage vessel ( 9 ) is connected between the lubricant feed line ( 8 ) and the lubricant device ( 5 ) of the bearing housing ( 4 ), and wherein the lubricant storage vessel ( 9 ) has a siphon ( 11 ). 6. An exhaust-gas turbocharger ( 1 ), having a compressor ( 2 ); a turbine ( 3 ); and a bearing housing ( 4 ) which has a lubricant device ( 5 ) for shaft bearings ( 6 , 7 ), which lubricant device is connected via a lubricant feed line ( 8 ) to an engine lubricant circuit, wherein a lubricant storage vessel ( 9 ) is connected between the lubricant feed line ( 8 ) and the lubricant device ( 5 ) of the bearing housing ( 4 ), and wherein the lubricant storage vessel ( 9 ) is provided with at least one heating element ( 13 ). 7. A lubricant storage vessel ( 9 ) for an exhaust-gas turbocharger ( 1 ), wherein the lubricant storage vessel ( 9 ) has a feed connector ( 10 ) which is screwed into a turbocharger bearing housing ( 4 ), wherein the lubricant storage vessel ( 9 ) has a siphon ( 11 ). 8. The lubricant storage vessel ( 9 ) according to claim 7 , wherein the lubricant storage vessel has a line port ( 12 ) which can be connected to a lubricant feed line ( 8 ) of the turbocharger. 9. A lubricant storage vessel ( 9 ) according to claim 7 , wherein the lubricant storage vessel ( 9 ) is provided with at least one heating element ( 13 ).
