摘要： A controlling motor for moving a stem along an axis has a hydraulic actuator with a cylinder in which a piston that is frictionally linked to the stem is slidingly and sealingly mounted, as well as a compression spring that is frictionally linked to the stem and acts against the actuator. The controlling motor has a trigger with an inflow area into which hydraulic fluid may be introduced, a pressure area that communicates with the inflow area through a diaphragm and is connected to the actuator, and a drainage area from which the hydraulic fluid may be evacuated without pressure, as well as a switching element that links the pressure area to the drainage area when a positive pressure differential occurs between the pressure area and the inflow area, and that otherwise shuts off the drainage area. The stem may be pushed out of the cylinder by the compression spring and may be drawn into the cylinder when hydraulic fluid is applied to the inflow area. This controlling motor is particularly suitable for driving a rising stem quick-action stop valve, such as those often used for example in steam power stations.

摘要： 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.
