ABSTRACT:
In a stabilizing device for extending the characteristic diagram of a compressor, which consists of a ring permanently attached to the impeller vanes of the impeller and a recess in the casing of the compressor in the form of a rotationally symmetrical groove, the ring is limited to the inlet region of the impeller and attached there in such a way that on rotation of the impeller, the ring can be moved in the recess, there being only a conventional close clearance between the ring and the wall of the casing. Due to this structure, the formation of a gap flow from the side of the vane at high pressure to that at low pressure is prevented, which leads to an increase in the efficiency of the compressor and to the widening of the compressor characteristic. The vibration loading on the vanes is lowered at the same time.
