Publication number: 20120128479Abstract: The guide device for the diffusor at the compressor impeller outlet of a radial compressor has guide blades with stepped inlet edges. The step is implemented by setting back the hub-side inlet edge. This meridional stepping divides the guide blades into two component blades, of which the first component blade is made longer than the second component blade. The set-back of the inlet edge of the hub-side component blade and the associated superposition of the noise fields which are produced on the front and rear inlet edge of the diffusor leads to improvement of the acoustic properties of the compressor.Type: ApplicationFiled: January 31, 2012Publication date: May 24, 2012Applicant: ABB Turbo Systems AGInventors: Janpeter KÜHNEL, Heinz-Jürgen FELD, Christine LINDBLOM

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

Patent number: 7374402Abstract: The fastening arrangement (26) for an impeller (22) on a shaft (14), in particular for an impeller (22) of a turbocharger on a turbocharger shaft (14), comprises a bush (34), which can be screwed onto a shaft journal (20) of the shaft (14), and a shaft-side hub extension (30) of the impeller (22) having a central recess (32), into which the bush (34) can be inserted in a frictional manner. The hub extension (30), at least in the region of its shaft-side end, is designed approximately in the form of a hollow cylinder. The fastening arrangement (26) also comprises a press sleeve (36) which can be frictionally connected radially on the outside to the hub extension (30).Type: GrantFiled: May 5, 2003Date of Patent: May 20, 2008Assignee: ABB Turbo Systems AGInventors: Martin Thiele, Janpeter Kühnel, Josef Bättig

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
