Abstract
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.
