ABSTRACT:
In a radial compressor the device for extending the performance at small throughputs by stabilizing the impeller flow in the inlet region comprises a recess (5) in the form of a groove which is oriented in the circumferential direction of the inlet duct (6) of the compressor, whereas in the flow direction it extends with a given axial width to the impeller (2). A stabilization ring (3) is integrated into said recess (5), being arranged in front of the impeller (2) and outside the principal flow (7) of the transported medium. A plurality of blades (4,4a), which are placed on the outer circumference of the stabilization ring (3), are in turn anchored to the inner contour of the recess (5).
