Abstract: A method for manufacturing a turbomachine shrouded wheel involves separately moulding a first green, moulded part forming a hub and blades, and a second green, moulded part forming a shroud, using a feedstock comprising a metal powder and a binder. The green, moulded parts are adjoined in a mated configuration, with additional feedstock placed between respective connection-surfaces on the moulded parts. The adjoined moulded parts are sintered to fuse them into a single unitary, monolithic structure. The moulded parts' connection-surfaces form conforming protrusions and depressions, which have surface discontinuities spaced at intervals along their respective lengths.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
