Abstract (en)
In a device for regulating the free cross-section in the guide vanes of pass-out turbines, pins (13) can be introduced between in each case two adjacent vane lobes of the guide vanes (12a) of the first stage, being introduced radially from the vane root (15) of the guide vane as far as the vane tip opposite the rotor (4) of the turbomachine, in the narrowest cross-section between two guide vanes (12a). <IMAGE>
