Abstract (en)
[origin: US4648790A] In an axial turbine for exhaust gas turbochargers, the inner wall of the rotationally symmetrical exhaust gas deflection duct is designed as a deflection collar rigidly connected to the turbocharger shaft and rotating with it. The outer diameter of the deflection collar is greater than the diameter of the turbine disc and, at maximum, equal to the outer diameter of the turbine rotor. An element for contactless sealing of the exhaust gas deflection duct is provided between the rotating deflection collar and the casing. The element for contactless sealing of the deflection duct preferably consists of two labyrinth seals located on a cylindrical surface opening inwards, the sealing air being supplied radially from within between the labyrinth seals by means of a sealing air duct.
