Compressor device of a supercharging device for an internal combustion engine

Compressor for charging a combustion engine, comprising a compressor housing () with a volute (), a compressor wheel () being arranged in the compressor housing (), the compressor wheel () turning about an axis (A) and transporting gas into the volute (), and an inlet channel (), at least an end portion of the inlet channel () being oriented in the direction of the axis (A) in order to direct gas towards the compressor wheel in the axial direction, wherein an exhaust gas channel () terminates into the inlet channel () upstream of the compressor wheel (), and wherein the exhaust gas channel () can be shut off by means of a valve (), wherein a housing () of a driving device () of the valve () is integrally formed with the compressor housing ().

Compressor for charging a combustion engine

An exhaust gas turbocharger () including a compressor housing (), a bearing housing (), a turbine housing () in which a turbine wheel () is arranged, which has a housing inlet (), which has a turbine spiral () connecting to the housing inlet (), which has a housing outlet (), and which has a wastegate arrangement (), which in the open state brings the housing inlet () into flow connection with the housing outlet () for guiding a wastegate mass flow. The wastegate insert part () is arranged in the turbine housing () between the turbine wheel () and the housing outlet () and the open wastegate arrangement () introduces the wastegate mass flow into the wastegate insert arrangement ().

Exhaust gas turbocharger

An exhaust-gas turbocharger () having a compressor () which has a compressor housing (); a turbine () which has a turbine housing (); and a compressor-side and/or turbine-side charge pressure regulating device () which has a shut-off element () which opens or closes a flow opening (). The shut-off element () is in the form of a slide which is mounted on a guide () so as to be longitudinally displaceable along a longitudinal central line (LM) of the guide (), and the flow opening () is arranged at least substantially at a right angle (&#x3b1;) with respect to the longitudinal central line (LM) of the guide ().

Exhaust-gas turbocharger

An exhaust-gas turbocharger () having a compressor () which has a compressor housing (); having a turbine () which has a turbine housing (); and having a charge-pressure regulating device (). The charge-pressure regulating device () has at least two flap arrangements () and two bypass duct openings () assigned to the flap arrangements ().

An exhaust-gas supply device () of a turbine wheel () of an exhaust-gas turbocharger (), having a two-channel turbine housing () and an exhaust manifold () which can be connected to an internal combustion engine (), which exhaust manifold () has a first manifold channel () which connects first cylinders (Z, Z) of the internal combustion engine () so as to form a first manifold exhaust-gas path length, and a second manifold channel () which connects second cylinders (Z, Z) so as to form a second manifold exhaust-gas path length, to generate virtually identical overall exhaust-gas path lengths of the two channels.
