FIELD: turbine machine engineering.
SUBSTANCE: turbine machine comprises nozzle block mounted coaxially between two housing members and made of several sectors provided with nozzle blades interposed between the members of inner and outer shelves. The members are provided with sealing spacers mounted radially in the space that spaces the members from the housing member. The spacers of two adjacent sectors are joined, and the joint is overlapped by means of a lining interposed between the spacers and locking member that locks the spacers in a position to seal. The locking member has lag mounted in one of the sectors and passing along the edge of the sector . The free end of the lag is pressed to the joint lining in the zone out of the sector.
EFFECT: enhanced reliability.
