In a compressor particularly of an exhaust gas turbocharger of an internal combustion engine having a compressor wheel rotatably supported in a compressor housing which includes a diffuser structure with an adjustable diffuser geometry comprising guide vanes pivotally supported, an adjustment ring is provided with engagement elements which engage forked end structures of the guide vanes at the outer ends of the guide vanes opposite the pivotal guide vane support so that the pivot position of the guide vanes can be adjusted by rotation of the adjustment ring.

Compressor, particularly in an exhaust gas turbocharger for an internal combustion engine

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.

Exhaust gas turbocharger for an internal combustion engine

In a turbine for an exhaust gas turbocharger including a turbine wheel with a number of turbine wheel blades supported in a housing, which defines a first radial inlet flow channel and which includes in the radial inlet flow channel a variable guide vane structure for guiding exhaust gas radially onto the turbine wheel, and a second, semi-axial, flow channel for guiding exhaust gas semi-axially to the turbine wheel, the turbine wheel blades are arranged and sized so as to define between circumferentially adjacent blades, a flow passage with a flow cross-section which has a minimum at its inlet end.

Turbine for an exhaust gas turbocharger

In an exhaust-gas turbocharger having a compressor and an exhaust-gas turbine, which drives the compressor and comprises a multipart exhaust gas supply duct manifold and a turbine rotor, to which pressurized exhaust gas can be delivered by way of the exhaust gas supply duct, the exhaust gas supply duct manifold includes at least three flow passages, which, except for one, are provided with shut-off flaps, which are adjustable independently of one another.
