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.

Turbine arrangement with separate guide device

A cartridge for use in a pulse energy enhanced turbine of a turbocharger. At least first and second fixed separating blades () are provided between a nozzle ring () and a disk (), the separating blades () maintaining separation of exhaust gas flows through a guide grid between a divided volute and a turbine wheel (). 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.

Cartridge for pulse-separated variable turbine geometry turbochargers

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

Adjustment mechanism with noise reducing features

A system for feeding operating gas to a drive () of a motor vehicle, including an atmosphere-side suction inlet () for air under atmospheric pressure, and a feed line () for the operating gas to the drive () under an operating pressure, the operating gas which is conducted to the drive comprising at least part of the air which is sucked in, at least part of the operating gas being conducted through a turbomachine () upstream of the drive () in a first operating type, the turbomachine () comprising an electric generator (), and the turbomachine () being operated in a second operating type as a compressor for the operating gas, an actuable valve arrangement () being provided, at least part of the air which is sucked in being conducted in a turbine direction (T) through the turbomachine () in a first position of the valve arrangement (), and at least part of the air which is sucked in being conducted in a reversed compressor direction (V) through the turbomachine () in a second position of the valve arrangement ().

System for feeding operating gas to a drive of a motor vehicle

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

Valve arrangement for multi-flow turbine

A compressor for a charging device, and a charging device having a corresponding compressor. The compressor comprises a compressor housing having a compressor inlet and a compressor outlet, and a compressor wheel and an adjustment mechanism. The compressor wheel is arranged in the compressor housing and can be rotated along a compressor axis. The adjustment mechanism is arranged in front of the compressor wheel axially in the current direction and can be adjusted between a first position and a second position in order to change an inlet cross-section of the compressor inlet. As a result of the adjustability of the adjustment mechanism, the inlet cross-section can be changed between a maximum inlet cross-section and a reduced inlet cross-section. Here, the adjustment mechanism forms the reduced inlet cross-section in such a way that the reduced inlet cross-section is arranged eccentrically in relation to the compressor axis.

Compressor having adjustment mechanism

The invention relates to a turbine comprising a turbine housing defining a volute having a substantially annular outlet opening, a turbine wheel, and an adjusting ring, rotatable about the turbine axis, which is arranged in the turbine housing radially between the volute and the turbine wheel, wherein the adjusting ring comprises a flow channel between a radially outer first peripheral opening and a radially inner second peripheral opening, and wherein the outlet opening is fluidically coupled to the turbine wheel by the flow channel. The outlet opening and the first peripheral opening have a path, variable in the axial direction, so that during a rotation of the adjusting ring, the outlet opening and the first peripheral opening are adjusted relative to each other in such a way that an overflow cross section between the outlet opening and the first peripheral opening is variably changeable.
