Abstract (en)

[origin: WO03080999A1] An exhaust gas turbocharger in an internal combustion engine comprises a compressor (20) inside the induction tract and an exhaust gas turbine (1) inside the exhaust gas line. The exhaust gas turbine (1) comprises at least two spiral ducts (4, 5) that each lead into a radial flow entry cross section (6, 7). A guiding screen ring (10) is placed in the radial flow entry cross sections (6, 7) and is held between two axially delimiting walls (15, 16). One of the walls (16) is designed so that it can axially move.
