ABSTRACT:
A steam turbine component and a steam turbine include a main axis and a separating element which is disposed in and fills a cross-sectional area at right angles to the main axis and which has at least one flow passage through which steam flows. A throttle element which can be displaced substantially along the main axis is provided for regulating steam flow through the flow passage. The throttle element has a first sealing surface and a second sealing surface. The sealing surfaces are in sealing contact with the separating element in a position closing the flow passage, and the sealing surfaces are at a distance from the separating element in a position at least partially opening the flow passage. The sealing surfaces are respectively located in a cross-sectional plane extending at right angles to the main axis, so that at most small frictional forces have to be overcome during opening of the flow passage and, in addition, a high degree of sealing is achieved.
