20090110547 | Method for producing a contoured gap, and turbo-engine comprising contoured gap - A method for producing a contoured gap between a rotor and a stator of a turbo-engine is provided. A first turbo-engine drives a second turbo-engine by means of a common shaft, the shaft being mounted in a bearing housing by means of a bearing. The aim of the invention is to enable the contoured gap to be created in a simple and reliable manner. To this end, the contoured gap is formed between a contoured surface of the rotor and a contoured surface of an engine housing associated with the rotor, by grinding the contoured surfaces against each other, using the axial play of the bearing. | 04-30-2009 |

20150152740 | COMPRESSOR WHEEL - A compressor wheel for an internal combustion engine may include a plurality of blades which in a circumferential direction of the wheel are spaced from one another. The plurality of blades may respectively include an inflow edge which during operation are subject to an inflow of a compressible fluid substantially axially to the wheel axis. The plurality of blades may include a surface layer of locally distinct materials to adapt to locally distinct loads during operation. | 06-04-2015 |
20150176433 | TURBINE HOUSING FOR AN EXHAUST GAS TURBOCHARGER - A turbine housing for an exhaust gas turbocharger may include a wastegate valve that may have at least two apertures. A first aperture may be configured to receive a wastegate shaft and a second aperture may be configured as an inlet to a bypass channel. An insert may include a valve seat for the wastegate valve and a bearing bush for mounting the wastegate shaft. The valve seat may be mounted by a matching valve disc. The valve seat may cover the second aperture and the bearing bush may cover the first aperture in an installed state of the insert. | 06-25-2015 |
