Abstract (en)
[origin: EP1394363A1] The device has a rotor housing with at least one fluid feed channel and a turbine rotor feeding the fluid via a variable turbine geometry control grating. A roller bearing is arranged between a displacement ring and a ring for reversible connection to the rotor housing, e.g. the blade bearing ring or a bearing ring, so that the displacement ring, roller bearing and reversibly connected ring can be fitted in the rotor housing as a modular unit. The device has a rotor housing (2) with at least one fluid feed channel (9) and a turbine rotor (4) feeding the fluid via a variable turbine geometry control grating (5-8). A roller bearing is arranged (3) between a displacement ring (5) and a ring (6) for reversible connection to the rotor housing, e.g. the blade bearing ring or a bearing ring, so that the displacement ring, roller bearing and reversibly connected ring can be fitted in the rotor housing as a modular unit.
