Abstract
FIELD: manufacture of compressors. SUBSTANCE: rim is provided with inner and outer hollow rings 2 and 3. Inner wall of outer ring 3 and outer wall of inner ring 2 are provided with radial holes which are used to communicate chambers of rings 2 and 3 with inter-blade passages. Holes of rings 2 and 3 are located over closed loop equidistant relative to contour of blade 1 at point of its attachment. Rings 2 and 3 are provided with circular partitions 5 and 6 located in their chambers forming isolated chambers. EFFECT: enhanced efficiency due to reduction of secondary losses at flowing around blade 1 at point of its attachment to inner and outer rings. 2 cl, 3 dwg
