Zusammenfassung:	turbojet engines. SUBSTANCE: device has labyrinth with sealing ribs and mating stator segment ring with deflector and slot-like space in between secured on last disk of compressor. Segment ring is secured on flange to, form additional slot-like space between flange and deflector. This space is connected at inlet with slot-like space between segment ring and deflector and at outlet, with unloading space. Cellular segments are installed on segment ring telescopically by means of axial and c-shaped flanges. Cellular segments fixed by detachable dowels from ring slots with segment ring. Turbolators in form of large-number ring radial ribs mechanically engaging with axial ribs of deflector are made from other side of ring opposite to ring slots. EFFECT: increased reliability and repairability of device owing to intensive two-side cooling of deflector. 3 dwg
