Patent number: 10066498Abstract: A turbine for a supercharging device of an internal combustion engine may include a turbine wheel which is rotatably arranged about an axis of rotation in a turbine housing. A radial inflow channel may be arranged coaxially to the turbine wheel, which leads to a radial inlet region of the turbine wheel. The inflow channel may be axially bounded on one side by a blade carrier and axially bounded on the other side by a cover disc. A plurality of guide blades may be pivotably arranged on the blade carrier, and a plurality of spacer elements may axially project from the blade carrier. An axial outflow channel may be arranged coaxially to the turbine wheel, which leads from the inlet region to an axial outlet region of the turbine wheel, which may be radially bounded by an inner contour formed complementary to an outer contour of the rotating turbine wheel.Type: GrantFiled: September 3, 2014Date of Patent: September 4, 2018Assignee: Bosch Mahle Turbo Systems GmbH & Co. KGInventor: Dirk Naunheim

Patent number: 9732623Abstract: A charging device for an exhaust gas turbocharger of an internal combustion engine may include at least one variable turbine and compressor geometry and an adjusting device for adjusting the at least one variable turbine and compressor geometry. The adjusting device may include a minimum set limit, which defines a minimum set flow of the at least one variable turbine and compressor geometry for an exhaust gas driving the charging device, and a maximum set limit, which defines a maximum set flow of the at least one variable turbine and compressor geometry for the exhaust gas driving the charging device. The adjusting device may be designed such that at least one minimum set limit of the adjusting device and the maximum set limit of the adjusting dive are variably adjustable and readjustable.Type: GrantFiled: March 2, 2012Date of Patent: August 15, 2017Assignee: Bosch Mahle Turbo Systems GmbH & Co. KGInventors: Jochen Schaeflein, Dirk Naunheim
