Abstract: A steam turbine (1) having an upper housing part (4) and a lower housing part (5), in which the steam turbine (1) has at least one overflow line (18) between a live steam adjusting valve (8, 9) and a high-pressure steam turbine inlet, and the valve housing (14) of the live steam adjusting valve (8, 9) communicates with the overflow line (18) via a flange connection (27), and a live steam pipe (25) in the live steam adjusting valve (8, 9) is provided as a steam duct between the valve housing (14) and the overflow line (18), and a sealing element (19) is disposed between the live steam pipe (25) and a sealing seat (28) in the overflow line (18), is distinguished in that an annular chamber (24) between the live steam pipe (25) and the valve housing (14) is provided with a pressure relief line (21) into a chamber of lower pressure than the live steam pressure.

Abstract: In a brush seal for sealing off the gap between a rotating and a stationary component, a plurality of radially inwardly running, elastically flexible brushes are held at one end in a basic body seated in a first of the components. They bear sealingly at the other end on the annular other component. The brushes bear, over their predominant longitudinal extent, on a guide plate. Both the basic body and the guide plate are seated in a groove of one of the components. The basic body and the guide plate are held in their mutual position by means of a wire mortised into the groove.
