Abstract (en)
[origin: EP0741247A2] The ring (10) has several points for support on a compressor housing, and curved ring segments (12) between two neighbouring support points. When the temperature of the segments rises, their curvature decreases. This moves the support points radially outwards. The ring has a min. of three and a max. of sixteen ring segments. Each segment has an outer circumferential section (14) and an inner bearer section (18). The two sections have different heat expansion coefficients in circumferential ring direction, and that of the inner section is the larger.
