Abstract (en)
[origin: EP0508067A1] A device for the regulated admission to the diffusor (7, 20) of axial flow tapped steam turbines (3, 3') essentially comprises a control slide valve (14, 23) having two inlet apertures (15, 22) for the working medium and arranged upstream of the diffusor, and a duct element (10, 19) arranged between the control slide valve (14, 23) and diffusor (7, 20). This is provided with a plurality of feed ducts (13, 21) which connect the inlet apertures (15, 22) of the control slide valve (14, 23) to the nozzles of the diffusor (7, 20). The control slide valve is rotatable by 180 DEG in a circumferential direction for increasingly opening or closing the feed ducts. <IMAGE>
