Abstract: The invention relates to a valve assembly (100) for a multi-scroll turbine (10) for controlling an overflow of exhaust gases between a first spiral (36) and a second spiral (38) and for controlling a bypass opening (50). The valve assembly 100 comprises a lever (110) and a valve closing element (120) which is operatively connected to the lever (110). Furthermore, the valve assembly (100) comprises a spring element (130) which is designed to pre-bias the valve closing element (120) the against lever (110).

Abstract: A device for orienting a packaging, such as a sterile packaging. Orienting the package comprises one or more of folding open or tightening at least one edge of the packaging in a substantially horizontal plane. The device arranges the packaging into a working position in which the packaging is oriented. The device comprises a brush station having at least one substantially horizontally oriented rotating brush designed and arranged to come into frictional contact with the at least one edge of the packaging.

Abstract: An exhaust-gas turbocharger (1) having a turbine housing (2), which has a bypass duct (10) with a bypass opening (9); and having a control flap (3), which is mounted pivotably between a closed position and an open position in the turbine housing (2), the control flap (3), when in its closed position, resting on a bearing region (8) of a housing wall (11) which conducts exhaust gas and contains the bypass opening (9), wherein at least one flow imperfection (12A, 12B; 23A, 23B) is arranged in the turbine housing wall (11) in the bearing region (8) of the control flap (3) and/or in the control flap (3).

Abstract: An exhaust-gas turbocharger component (10) having at least one flow-conducting component surface (11) and having a discontinuity structure (12) which is formed on the component surface (11). The discontinuity structure (12) has a multiplicity of punctiform depressions (13) which are arranged separately from one another on at least one part of the component surface (11).

Abstract: The invention relates to a turbocharger (1) in which, for damping the wastegate flap/wastegate lever system, an axially acting spring element is provided in order to reduce wear. The turbocharger (1) comprises a compressor (2) and a turbine (3) which has a turbine housing (4) and a wastegate device (6) with a regulating flap (7). The flap plate (7?) of the regulating flap (7) is arranged, via a lever (5), on a regulating flap shaft (9) which is guided in the turbine housing (4) by means of a bush (8). Here, the flap plate (7?) is preloaded against the lever (5) by means of a spring element (10).
