Publication number: 20110318164Abstract: The means of sealing the compressor wheel with respect to the bearing housing includes an annular sealing element which forms a sealing boundary face with a shaft edge and to which a spring force is applied in the direction of the shaft edge. The external spring force neither compensates or amplifies the pressure forces acting on the sealing element, irrespective of the direction of the difference in pressure. As a result, the sealing of the oil space in the bearing housing of the exhaust gas turbocharger with respect to the shaft is not influenced, or is influenced only to a small degree, by the pressure fluctuations in the wheel back space of the compressor.Type: ApplicationFiled: June 23, 2011Publication date: December 29, 2011Applicant: ABB Turbo Systems AGInventors: Adrian Kopp, Christoph Häge, Martin Thiele

Publication number: 20080075583Abstract: The guiding device of a turbine has guide vanes which are rotatably mounted in the turbine housing. A sealing sleeve is arranged between the turbine housing and the guide vane stem. The additional axial compression spring ensures that the sealing sleeve is continuously pressed onto the guide vane mating contour, and that the axial gap and also the leakage flow are prevented as a result.Type: ApplicationFiled: November 7, 2007Publication date: March 27, 2008Applicant: ABB Turbo Systems AGInventors: Joel Schlienger, Adrian Kopp

Patent number: 7344362Abstract: In a turbocharger (1), comprising a turbine (2) and a compressor (3) connected to the turbine (2), the turbine (2) contains a turbine wheel (4) and the compressor (3) contains a compressor wheel (7) which are connected to one another by means of a shaft (10) and are arranged in a housing (5, 9, 16). During operation, if the compressor wheel (7) separates from the shaft (10), an axial force acts on the turbine wheel (4) and the shaft (10) connected thereto. A means (22, 25) for axially locking the shaft and the turbine wheel connected thereto in the housing (5, 9, 16) is arranged on the shaft (10) connected to the turbine wheel (4).Type: GrantFiled: April 10, 2003Date of Patent: March 18, 2008Assignee: ABB Turbo Systems AGInventors: Adrian Kopp, Marco Gartmann, Tobias Gwehenberger

Patent number: 7329090Abstract: The use of spring clamping clips between two adjacent guide vane shafts leads to a defined force on the bearing points of the guide vane in the guide bush. The seating force, resulting from the clamping force and the flow-related lift/drift forces, of the guide vane in the guide bush is therefore always positive and the guide vane rests constantly in the guide bush.Type: GrantFiled: September 14, 2005Date of Patent: February 12, 2008Assignee: ABB Turbo Systems AGInventors: Joel Schlienger, Adrian Kopp

Publication number: 20070231125Abstract: The preswirl guide device for generating a preswirl in the intake region of a compressor comprises a multiplicity of guide vanes, which are pivotable about a respective vane shank connected to the guide vane, and a pivotable adjusting ring and adjusting levers for transmitting torque from the adjusting ring to the vane shank of each guide vane. The vane shank and the adjusting lever of the respective guide vanes are of one-piece design. The casing in which the guide vanes are rotatably mounted consists of at least two parts joined together in the region of the bearings of the guide vanes. Due to the one-piece design of the guide vane, the number of components to be fitted is reduced. This simplifies the fitting and possible service work on the guide device.Type: ApplicationFiled: March 28, 2007Publication date: October 4, 2007Applicant: ABB Turbo Systems AGInventors: Daniel Oeschger, Josef Battig, Adrian Kopp, Janpeter Kuhnel

Patent number: 7008182Abstract: The exhaust-gas turbine comprises a turbine wheel arranged on a shaft, a bearing casing for the bearing arrangement of the rotatable shaft, a gas-inlet casing supported on the bearing casing and concentrically surrounding the bearing casing in the supporting region, and a centering ring for centering the gas-inlet casing relative to the shaft mounted in the bearing casing. The centering ring and either the bearing casing or the gas-inlet casing comprise grooves and either radially or axially unidirectional centering lugs for engaging in the grooves. Due to the radially or axially unidirectional centering lugs with corresponding grooves, at least one of the connections between the bearing casing and the centering ring and the centering ring and the gas-inlet casing is not positive-locking, as a result of which any desired positioning of the gas-inlet casing relative to the bearing casing is made possible.Type: GrantFiled: March 5, 2004Date of Patent: March 7, 2006Assignee: ABB Turbo Systems AGInventors: Adrian Kopp, Josef Bättig, Marcel Meier
