A turbomachine includes a housing and a rotating group supported for rotation about an axis of rotation within the housing. The rotating group includes a wheel and seal member that is unitary. The wheel and seal member includes a first wheel feature and a second wheel feature that are disposed in a back-to-back arrangement with an outer radial area disposed between the first and second wheel features and facing radially outward from the axis of rotation. The turbomachine also includes a plurality of labyrinthine seal members included on the outer radial area that cooperatively define, with the housing, a labyrinthine seal.

A fluid compressor device includes a compressor section and a motor section. The compressor device further includes a working fluid first flow path that extends in a downstream direction through the motor housing to the compressor inlet. The working fluid first flow path is configured to receive a first flow of a working fluid that flows downstream through the motor housing past the electric motor and into the compressor inlet to be compressed by the compressor section. Additionally, the compressor device includes a working fluid second flow path extending through the housing. The working fluid second flow path is configured to receive a portion of the working fluid from the compressor section and direct the portion to the bearing system before merging with the working fluid first flow path.

A turbomachine includes a housing, a rotating group that is housed within the housing, and a fluid bearing system with a thrust member. The turbomachine further includes a compressor stage configured to receive a fluid from an area within the housing. Also, the turbomachine includes a seal plate of the housing. The seal plate includes a first face and a second face. The first face has a flow surface that at least partly defines a fluid flow path toward the compressor wheel. The second face has a thrust member support surface configured to support the thrust member during rotation of the rotating group. The seal plate includes an aperture that fluidly connects the area to the fluid flow path.

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

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

An assembly can include a compressor backplate; a bearing boss that extends axially from the compressor backplate and that includes an outer surface and male coupling features disposed along the outer surface; and a casing that includes a compressor end, a bearing boss opening at the compressor end, a turbine end, an inner surface located between the compressor end and the turbine end and female coupling features disposed along a portion of the inner surface, the male coupling features and the female coupling features configured to couple the bearing boss to the casing. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.

Turbocharger center housing

A system can include a turbine housing that defines a turbine wheel space, an exhaust chamber in fluid communication with the turbine wheel space and a control shaft bore that extends from the exhaust chamber to an outer surface of the turbine housing; a blunt body positionable above the turbine wheel space where the blunt body includes an opening and a lumen in fluid communication with the opening; and a suction conduit connectable for fluid communication between the control shaft bore of the turbine housing and the lumen of the blunt body. Various other examples of devices, assemblies, systems, and methods are also disclosed.

Suction sealing for turbocharger

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.
