Turbocharger for an internal combustion engine

摘要

The device has an exhaust turbine with rotor (7), having a radial and a semi-axial flow intake. At least one of the two intakes (7a,b) is at least partially closed by a ring sleeve (18). The sleeve slides in direction of the longitudinal rotor axis (17). One end face (19) of the ring sleeve engages on the ring (15), which forms the ring nozzles in the flow channel, and seals one of the intakes almost completely, leaving only gap flows. A guide blade ring (20) is fastened to the sleeve end face, and projects into a blade ring space (24) of the nozzle ring.
