摘要： An exhaust-gas turbocharger for an internal combustion engine has a turbine in the exhaust-gas tract and a compressor, driven by the turbine, in the intake tract, the turbine having a flow channel with a radial flow-inlet cross-section and a semi-axial flow-inlet cross-section, and a flow ring being provided which limits the two flow-inlet cross-sections. The turbine is furnished with variable turbine geometry for the changeable adjustment of the flow-inlet cross-section. To improve efficiency, the position of the flow ring in the housing of the exhaust-gas turbocharger is variably adjustable.

摘要： An exhaust gas turbocharger for an internal combustion engine comprises a turbine in the exhaust line and a compressor, which is driven by the turbine and which is located inside the intake tract of the internal combustion engine. The turbine comprises a flow duct having a radial flow entrance cross-section, and a flow ring is provided that delimits the flow entrance cross-section. An adjustable vane is placed in the radial flow entrance cross-section for variably adjusting this flow entrance cross-section. The flow ring inside the housing of the exhaust gas turbine can be axially displaced between a contact position toward the vane and a position that frees a gap toward the vane.

摘要： An exhaust gas turbocharger comprising a turbine with a guide apparatus comprising a ring of guide vanes arranged concentrically around a rotor axis and pivotable between two end limits. A first securing ring is arranged at the side of a bearing housing for mounting a first trunnion of each guide vane which is also mounted at the side of an oppositely disposed turbine housing. An adjusting mechanism is provided for adjusting one of the two end limits, and the guide vanes are freely pivotable under the influence of flow forces in the resulting predetemined angle adjustment range. The arrangement makes possible a compact construction which can be fabricated at reduced cost and easily assembled. This is achieved by an assembly containing the guide apparatus and the adjusting mechanism, and which includes a second securing ring arranged at the side of a turbine housing for mounting a second trunnion of each guide vane. The assembly has an inner diameter which is larger than the outer diameter of the turbine wheel, and the two securing rings are connected to each other in axially spaced relation by connecting elements to form a flow channel in which the guide vanes are disposed.
