LINEAR LAYING FOR INTERSCAPULAR SHELF Russian patent published in 2017 - IPC F01D11/00 

FIELD: machine building.

SUBSTANCE: linear laying (10; 10') for interscapular shelf, which has a length, at that, the laying comprises a linear base (12; 12') for fastening on the interscapular shelf (40) and a linear projection (14; 14') projecting from a linear base (12; 12'). Linear projection (14; 14') has a linear distal end section (14a), adapted to be in contact with the pressure side wall (52a) or the blade back (50) wall (52d), the linear recess (16; 16') formed between the linear base (12; 12') and the linear projection (14; 14') at least at the part of the length of the noted linear laying (10; 10'). The linear distal end section (14a; 14'a) has at least one linear slit (120; 120') extending over at least part of the noted laying (10; 10') length. Due to the linear slit, the distal end section locally becomes more flexible, thus, the slot enables the protrusion snug fit to the blade contour.

EFFECT: improved seal tightness and increased service life of the laying.
