FIELD: sealing facilities. SUBSTANCE: invention relates to sealing device of two chambers of different pressures by means of shoulder taking up axial forces formed between first heated metal structural part and second heated metal structural part installed with radial clearance relative to first part, particularly, between stator or cover of housing and housing of turbomotor. Said device has seal adjoining the shoulder and overlapping radial clearance. Seal consists of carrying member of approximately rectangular section installed for axial displacement and including special means pressing side of carrying member pointed to means to shoulder. Seal overlaps radial clearance between carrying member and part of structure. Side of carrying member opposite to shoulder is made for loading from side of higher pressure chamber. EFFECT: improved reliability of sealing. 6 cl, 1 dwg
