Date Jul. 25, 1996Fluid-flow machine having shaft (1) which is mounted in an axially fixed fashion, and a balancing piston (6) firmly arranged thereon. In order to reduce the leakage flow, the balancing piston (6) is partially replaced by a porting ring (12) which forms with the balancing piston a choke gap (11), through which radial flow occurs, and a cylindrical upstream throttle (13) through which axial flow occurs. |
