<p>Diffuser blades (16) which can be rotated about radially orientated axes (28) are mounted by means of trunnions (22, 23) externally on a shell (18) and internally in a trunnion bearing housing (24). Attached to the trunnions (23) situated on the inside there are regulating levers (27, 29) which can be actuated by an adjusting collar which can rotate about the rotor shaft (17) and can be rotated with the aid of a regulating body (37). By adjusting the diffuser blades via the inner rather than the outer trunnions, space and material can be saved. Moreover, the regulating units are better protected. <IMAGE></p> |
