Patent number: 7771161Abstract: Guide vanes are supported in a two-part or multipart housing (32, 33). Housing separation takes place radially in the region of the bearing point (25) of the vane shaft so that the separating joint (36) between the housing parts (32, 33) leads through the bearing openings (34) which are designed to hold the vane shafts. The completely round opening (34) leads to the bearing point of the vane shaft having large-area support in any position. Thus high surface pressures can be avoided.Type: GrantFiled: January 18, 2007Date of Patent: August 10, 2010Assignee: ABB Turbo Systems AGInventors: Josef Bättig, Jean-Yves Werro, Janpeter Kühnel

Publication number: 20080260521Abstract: A sealing assembly comprises a bore in a housing, a plurality of seal rings and a shaft. The bore comprises a plurality of seats disposed at different seat radius for the seal rings. The bore comprises for each pair of adjacent seats axially inward of an inner end of the outward seat and proximate to the inward seat a chamfer extending radially inwardly over an inward axial distance. The chamfer between each pair of seats allows for the radial contraction of the seal rings upon assembly.Type: ApplicationFiled: June 17, 2008Publication date: October 23, 2008Applicant: ABB TURBO SYSTEMS AGInventors: Jean-Yves Werro, Ulrich Wellenkamp

Patent number: 7229061Abstract: A device for fastening a turbocharger to a base, with a fastening foot (12) which is integrally formed in one piece on a gas outlet casing (10) of the turbocharger and which has long holes (16) spaced from one another and preferably arranged in a star-shaped manner in relation to one another. In order to fasten the turbocharger, sliding shoes (26) are capable of being inserted into the long holes (16) and have continuous orifices, through which can be led fastening elements (30, 30?) capable of being fixed in the base.Type: GrantFiled: July 17, 2001Date of Patent: June 12, 2007Assignee: ABB Turbo Systems AGInventors: Josef Bättig, Jean-Yves Werro

Publication number: 20070101713Abstract: An exhaust-gas turbocharger with a compressor casing, turbine housing and bearing housing is supported on a base in the area of the bearing housing by means of a first support and in the area of the turbine housing by means of a second support. The second support is made in at least two parts, whereby the two parts can be moved relative to one another in the support direction. As a result, the length of the supports can be varied and counterbalance a temperature-related raising or lowering of the exhaust-gas turbocharger housing.Type: ApplicationFiled: November 16, 2006Publication date: May 10, 2007Applicant: ABB TURBO SYSTEMS AGInventors: Josef Battig, Marcel Meier, Jean-Yves Werro, Ulrich Wellenkamp

Patent number: 6024495Abstract: The object of the invention is to provide a simple and cost-effective solution for reducing the wear and consequently for increasing the life of axial sliding bearings. For this purpose, the profiled annular surface (24, 24') of the lubricating gap (25, 25') arranged between the fixed bearing body (20) and the rotating bearing collar (19) is designed to rotate about or with the shaft (14). Said annular surface has a plurality of radially arranged lubricating oil grooves (26, 26') and, in each case, a wedge surface (27, 27') connected to these in the circumferential direction. A catch surface (28, 28') is designed between each wedge surface (27, 27') and the lubricating oil groove (26, 26') adjacent to the latter. The lubricating oil grooves (26, 26') and the wedge surfaces (27, 27') are delimited radially outward by a sealing web (29, 29').Type: GrantFiled: September 18, 1997Date of Patent: February 15, 2000Assignee: Asea Brown Boveri AGInventors: Markus Loos, Jean-Yves Werro, Raimund Wohlrab

Patent number: 5938402Abstract: Improved cleaning of the nozzle ring and the moving blades of the axial turbine of a turbocharger is to provided by a cleaning device. The cleaning device (20) includes only one nozzle (21, 44) having at least one injection opening (24) as well as a cleaning-agent feed line (23). The injection opening (24) is arranged at any point (38) of an imaginary circular area (34), which in turn is defined by a center (33) arranged at a distance A upstream of the inner casing wall (11) as well as by a diameter d.sub.k. The center (33) lies on an imaginary parallel area (34) formed at a distance A from the inner casing wall (11). The distance A corresponds to the average diameter of the nozzle ring (8) multiplied by a percentage P.sub.1, (5%.ltoreq.P.sub.1 .ltoreq.30%). The center (33) lies at an intersection point (36) of the parallel area (35) and die flow line (17) intersecting the latter at right angles. The diameter d.sub.Type: GrantFiled: December 5, 1997Date of Patent: August 17, 1999Assignee: Asea Brown Boveri AGInventors: Dominique Bochud, Markus Kohling, Jean-Yves Werro
