FIELD: engines and pumps.
SUBSTANCE: turbine includes rotating component and stationary component including the diaphragm having an annular group of stator blades located about the turbine axis. Diaphragm has a groove including the sealing carrier having the sealing surface located opposite sealing teeth on rotating component. Sealing surface is made from worn out material worn out with the rotating component. On the sealing carrier, along its surface facing the axial direction, there made is the second sealing surface located opposite the sealing surface of diaphragm. Carrier of sealing is provided with possibility of being moved in axial direction for forming the sealing between sealing surface of diaphragm and the second sealing surface. The second sealing surface has the worn out material worn out with the sealing surface of diaphragm.
EFFECT: invention allows increasing turbine efficiency owing to decreasing steam leakages.
