A turbine housing of a turbocharge can include a surface that defines a portion of a volute, an annular surface that extends radially inwardly to define a portion of a pressure chamber that is in fluid communication with the volute, a substantially annular plate that defines a portion of the pressure chamber, an annular component, at least one spacer that defines a minimum axial distance between the substantially annular plate and the annular component to define a nozzle that is in fluid communication with the volute and in fluid communication with a turbine wheel space where, responsive to fluid flow in the volute and through the nozzle to the turbine wheel space, the pressure chamber has a fluid pressure that exceeds a fluid pressure of the nozzle to apply a biasing force to the substantially annular plate in an axial direction toward a center housing.

Turbocharger turbine assembly

A turbocharger assembly can include a center housing; a turbine housing; and an insert disposed between the center housing and the turbine housing where a surface of the turbine housing and a first surface of the insert define a volute and where a surface of the center housing and a second surface of the insert define a chamber.

Turbocharger assembly

A turbocharger having a variable-nozzle turbine formed by pivotable vanes supported by a nozzle ring includes a locator that is radially elastically deformable and is disposed between a radially outwardly facing surface of the center housing and an opposing surface of the nozzle ring for radially locating the nozzle ring relative to the center housing. At least one vent is defined in either a radially outermost surface of the locator or the surface of the nozzle ring to allow pressure communication between spaces on axially opposite sides of the locator.

Variable-nozzle turbine with means for radial locating of variable-nozzle cartridge

An assembly for a turbocharger can include a shaft and turbine wheel assembly and a component that has a rotational axis and that includes a through bore for receipt of the component by the shaft of the shaft and turbine wheel assembly where the component includes an inner surface and an outer surface and one or more passages that extend between the inner surface and the outer surface, where the one or more passages are shaped to exert force on the component responsive to flow of fluid in the one or more passages and where the force rotates the component about the rotational axis. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.

Turbocharger lubricant turbine

A turbocharger assembly can include a center housing that includes a compressor side, a turbine side, a bore that extends between the compressor side and the turbine side and a socket at the compressor side; a journal bearing disposed in the bore; and a lubricant deflector disposed at least partially in the socket. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.

Turbocharger with lubricant deflector

A diffuser plate for a centrifugal compressor includes an inner edge disposed at an inner diameter about a central axis; an outer edge disposed at an outer diameter, the outer edge displaced an axial distance from the inner edge; a deformable section that includes a substantially S-shaped cross-section, the deformable section disposed between the inner edge and the outer edge; and a spring constant for forced axial displacement of the outer edge with respect to the inner edge, the spring constant characterized, at least in part, by the deformable section.

Compressor diffuser plate

A turbocharger housing includes a main body for bearing a shaft for carrying a turbine wheel and a compressor wheel, and a seal portion to seal a clearance between the shaft and the turbocharger housing, where the seal portion is formed by an insert being fitted to the main body, where the insert includes a passage for supplying a fluid to the seal portion.

Turbocharger housing, turbocharger and a multi-turbocharger boosting system

A turbocharger comprises a variable nozzle device and an exhaust housing being mechanically and/or thermally decoupled from the variable nozzle device. Additional optional advantageous features are provided, including various axial and radial clearances and various sealing elements.

Turbocharger comprising a variable nozzle device

A calibration flow position of a variable nozzle () of a turbocharger is set by a method for calibrating the turbocharger, which comprises a turbine () and a compressor (). In this method, the turbocharger is driven by a predetermined fluid supply. Further, the flow position of the variable nozzle () is changed while the rotational speed (N) of the turbocharger or an outlet pressure (P) of the compressor () is monitored. The calibration flow position is fixed based on the monitored quantities.

Method for calibrating a turbocharger

A nozzle device for a turbine of a turbocharger according to the present invention comprises variable annular nozzle () defined between an inboard wall () and an outboard wall (), wherein said outboard wall () is axially movable for completely closing said variable annular nozzle ().

Variable nozzle device for a turbocharger

A cartridge is formed by an insert fixed to a base to form turbine intake nozzles in which vanes are rotatably mounted, and the base is fixed to a center housing. A separate exhaust housing which is formed from sheet metal is fixed to the cartridge outside of the insert in order to provide an intake and an outlet for exhaust gases driving a turbine wheel on a shaft journaled in the center housing.
