Abstract (en)
[origin: EP0439757A1] An axial swirl controller for large-capacity radical compressors has a flow duct, which passes from a first cylindrical section (15) via a spherical section (16) nozzle- shaped into a second cylindrical section (17), which for its part has a circumferential surface which has an incline of between slightly more than 0 DEG and 10 DEG in relation to an axially parallel circumferential surface. The guide vanes (22) supported in the transitional plane from the first cylindrical section (15) to the spherical section (16) have an axis of rotation (23) which divides the guide vane surface in a ratio of 1/3 : 2/3. The ratio of the diameter (D1) of the first cylindrical section (15) to the diameter (D2) at the inlet of the second cylindrical section (17) is between 1.1 and 1.4. The guide vanes (22) are adjusted by means of an adjusting collar (31) mounted on the outside of the casing, which collar acts on the axis of rotation (23) of the guide vanes (22) by way of an articulated lever (25). <IMAGE>
