A valve () controls a volute connecting opening () and a bypass opening () of a dual-volute turbine (). The valve () has valve closing body (), a lever arm () and a spindle (). The valve closing body () has a main body () and a collar (). The valve () is of a monoblock design with the valve closing body (), the lever arm () and the spindle () being made of a single part.

Valve for a dual-volute turbine

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 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

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 ().

Valve assembly for a multi-scroll turbine

The invention relates to a turbocharger for an internal combustion engine, comprising a housing () with an exhaust-gas-side and an air-side turbine blade (), a shaft () connecting the turbine blades, and at least one radially acting rotary bearing for mounting the shaft (), wherein the rotary bearing is designed as a hydrodynamic floating bearing, wherein a lubricant flows in a completely surrounding bearing gap () of the rotary bearing in the direction of rotation and has a local lubricant pressure, the bearing gap () has a contouring () due to which the at least two local maxima (PM, PM) of the lubricant pressure are formed at two defined angular positions (W, W) in the direction of rotation.

Turbocharger for an internal combustion engine with a hydrodynamic floating bearing

A compact flow control valve capable of providing long service life in a very hostile environment. The valve is a mono or dual coaxial slider valve capable of controlling two different functions sequentially, at least one of the functions being controlled progressively. The flow control valve controls the fluid connection between two volutes () of a turbine housing () of a turbocharger as well as the fluid connection between the two volutes () of the turbine housing () of the turbocharger and a waste gate port ().
