FIELD: machine building.SUBSTANCE: steam turbine (10) comprises a casing (26), a rotor (12) and at least one flexible plate-like gland box (24) set between the casing and the rotor. The said gland box comprises a supporting element (28) fixed in respect to the casing, plate-like elements (48) which are set on the said supporting element, are able of moving, pass in the direction to the rotor and each of them is inclined in respect to the rotor rotation direction, and an actuator (32) designed for the selective application of pressure to provide for the retraction of the said plate-like elements in the direction from the rotor.EFFECT: improved design.9 cl, 11 dwg |
