Abstract: The present invention concerns an adjustment mechanism (200) for variable adjustment of an inlet cross-section (321) of a compressor inlet (322). The adjustment mechanism comprises a plurality of rotatably mounted baffle elements (210) which are arranged in a circumferential direction (26) and are adjustable between a first position and a second position. At least one baffle element (210) of the plurality of baffle elements (210) comprises an eddy-reducing feature (220).

Abstract: A cartridge for use in a pulse energy enhanced turbine of a turbocharger. At least first and second fixed separating blades (12) are provided between a nozzle ring (6) and a disk (29), the separating blades (12) maintaining separation of exhaust gas flows through a guide grid between a divided volute and a turbine wheel (11). Exhaust pulsation energy from different cylinders or cylinder groups of an engine or engine bank are kept separated up to the turbine wheel, so that the turbine wheel reacts to individual pulses of exhaust gas flow from engine exhaust ports.

Abstract: Disclosed is a turbine arrangement for a supercharging device. The turbine arrangement comprises a turbine housing, a turbine wheel and a guide device. The turbine housing defines a turbine spiral and a turbine outlet. The turbine wheel is arranged in the turbine housing between the turbine spiral and the turbine outlet. The guide device comprises a carrier ring and multiple guide blades. The guide blades are arranged on the carrier ring fixedly in a predetermined orientation. The guide device is arranged in an inflow channel between the turbine spiral and the turbine wheel such that, during operation, fluids are conducted from the turbine spiral through the inflow channel over the guide blades onto the turbine wheel.

Abstract: The present invention relates to a valve arrangement (100) for a multi-channel turbine (10), having a housing section (300) with a first volute (320), with a second volute (340) and with a connecting region (360) between the first volute (320) and the second volute (340), and having a valve body (110) for closing off the connecting region (360) in a closed position of the valve body (110). A wall region (370) of the housing section (300), which wall region is arranged in the connecting region (360) and is situated opposite the valve body (110) in the closed position, is configured to be optimized in terms of flow to increase, during operation of the valve arrangement (100), a rate of flow transfer of exhaust gas between the first volute (320) and the second volute (340) in an open position of the valve body (110).
