The disclosure relates to a valve assemblyfor controlling a volute connecting openingof a multi-channel turbine. The valve assemblycomprises a housing portion, a valve bodyand an internal lever. The housing portiondefines a first volute channel, a second volute channeland a volute connecting region. The housing portionfurther comprises a cavity. The cavityis separated from the volutesand can be accessed from outside the housing portionvia a housing openingwhich extends from outside the housing portioninto the cavity. The volute connection regionis located between the first volute channeland the second volute channeland defines a volute connecting opening. The valve bodyis inserted in the cavityof the housing portionand comprises at least one fin. The internal leveris coupled with the valve bodyand configured to pivotably move the valve bodybetween a first position and a second position. In the first position of the valve body, the finblocks the volute connecting opening

Valve assembly for multi-channel turbine

The invention relates to a valve assembly () for a multi-scroll turbine () for controlling an overflow of exhaust gases between a first spiral () and a second spiral () and for controlling a bypass opening (). The valve assemblycomprises a lever () and a valve closing element () which is operatively connected to the lever (). Furthermore, the valve assembly () comprises a spring element () which is designed to pre-bias the valve closing element () the against lever ().

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.

The invention concerns a flap arrangementfor a turbineof an exhaust-gas turbocharger, in particular for a wastegate valve of the turbine, having a spindlefor rotatable mounting of the flap arrangementin a turbine housing, a lever arm, the lever armbeing coupled to the spindle, and a flap plate, the flap platebeing coupled to the lever arm. The flap platehas a flexible partin a radially outer region of the flap plate, such that by applying a closing force to the flap arrangementwhen the flap plateis in contact with a flap seatin the turbine housing, elastic and/or plastic deformation of the flexible partof the flap platecan be caused to compensate for thermal deformation of the turbine housing, exhaust deposits and/or wear.

The present invention relates to an actuation device for a compressor inlet adjustment mechanism. The actuation device comprises a housing part and a lever assembly. The lever assembly comprises a bearing section, an input section and an output section. The output section is configured to be coupled to an adjustment ring of the adjustment mechanism on a first side of the housing part. The input section can be coupled to an actuator rod on a second side of the housing part. The lever assembly is rotatably mounted in the housing part via the bearing section on the compressor inlet side here.

An exhaust gas guide section for an exhaust gas turbocharger includes an actuator () with a wastegate () for opening and closing a bypass channel () of the exhaust gas guide section (), wherein the bypass channel () is provided in the exhaust gas guide section () that can be flowed through to bypass a turbine wheel of the exhaust gas guide section () which is rotatably arranged in the exhaust gas guide section () in a wheel chamber of the exhaust gas guide section (), and wherein the bypass channel () has a second flow cross section ().

Exhaust gas guide for an exhaust gas turbocharger and method for operating an exhaust gas turbocharger

The invention relates to a regulating device for a turbocharger. The regulating device () is received in a turbocharger () exhaust gas conducting section () through which exhaust gas can flow, and a fluid flow to a turbine wheel which is rotatably received in the exhaust gas conducting section () can be conditioned using the regulating device (). A flow channel () which is formed in the exhaust gas conducting section () is to be opened and closed using a cover element () of the regulating device (), and the cover element () is arranged on a regulating device () pivot arm () which can be pivoted about a rotational axis (). According to the invention, the cover element () is designed to open and close a flow channel designed as a bypass channel () for bypassing the turbine wheel and/or for opening and closing a flow channel, which is designed as a through-flow opening (), between a first spiral channel () and a second spiral channel () of the exhaust gas conducting section ().
