FIELD: mechanical engineering.
SUBSTANCE: sectors 25 of guide-vane assembly on which vanes are secured are arranged close to housing 31 by means of sealing sectors 32 alternating with said sectors in axial direction and are provided with surfaces 37, 39, offering resistance to forces, and by means of said surfaces, forces applied to sectors of distributing apparatus are conveyed to housing. Inner surface of housing 31 is smooth and has no hooks thanks to which housing 31 is easy to manufacture and is exposed to lower mechanical stresses at fastening of sectors of guide-vane assembly which can be set simply by axial movement.
EFFECT: simplified design of housing, convenience of assembling of guide-vane assembly.
