ABSTRACT:
A device for conducting cooling liquid in and out of liquid cooled rotor type machine such as an electric turbine generator. A discharging ring having small holes formed therein is disposed so as to cover an open end of an outflow pipe for cooling liquid from the rotor shaft. A first outlet chamber surrounds the open end of the outflow pipe to receive cooling liquid discharged through the discharging ring. A second outlet chamber having one end side integral with the first outlet chamber receives cooling liquid discharged through a seal between the first outlet chamber and the outflow pipe. Shielding gas is supplied into the first outlet chamber to maintain the pressure therein higher than atmospheric pressure. The first outlet chamber is only partially filled with cooling liquid.
