Abstract: A compressor device includes a housing and a rotating group with a shaft and a compressor wheel supported on the shaft. The compressor wheel includes a back face. The compressor device further includes a bearing that supports the rotating group within the housing for rotation about an axis. Also, the compressor device includes a spacer that is disposed longitudinally along the axis between the back face of the compressor wheel and the bearing. The spacer is received within a wall of the housing. Moreover, the compressor device includes a moisture removal system configured to receive and remove moisture included within a fluid flow from the back face of the compressor wheel to an area between the spacer and the wall of the housing. The moisture removal system includes a channel cooperatively defined by the spacer and the wall of the housing. The channel extends about the axis.

Abstract: A compressor device includes a housing and a shaft supported for rotation within the housing. The compressor device includes a compressor section with a compressor wheel. Also, the compressor device includes a thrust suppression section with a chamber and a thrust balance body disposed within the chamber. Moreover, the compressor device includes a motor configured to drivingly rotate the shaft, the compressor wheel, and the thrust balance body. The thrust balance body divides the chamber into a first sub-chamber and a second sub-chamber. Additionally, the compressor device includes a bleed air system that fluidly connects the compressor section and the thrust suppression section. The bleed air system is configured to bleed air from the compressor section, through the first sub-chamber, to the second sub-chamber, pressurizing the first sub-chamber and generating a counterbalancing thrust load that counterbalances a compressor thrust load on the shaft.

The e-charger additionally includes a cooling system with passages cooperatively defined by the outer housing and the motor case. First and second longitudinal passages extend between the first and second ends of the motor, and a second longitudinal passage extends between the second and first ends of the motor. The end passage fluidly connects the first and second longitudinal passage. The cooling system is configured for directing flow of the coolant from the inlet, through the first longitudinal passage in a first longitudinal direction with respect to the axis, through the end passage, and back through the second longitudinal passage in a second longitudinal direction with respect to the axis.

Abstract: In a turbocharged internal combustion engine (ICE) system, a catalytic treatment device receives exhaust gases from the ICE after they have passed through the turbocharger turbine. The system includes a secondary air pump (SAP) for injecting pressurized air into the exhaust gases ahead of the catalytic treatment device. The SAP is a single-stage centrifugal compressor that includes an air recirculation passage for causing a first portion of the air pressurized by the SAP to be continuously recirculated back to the inlet of the SAP, which is effective for heating the air in the volute of the SAP. A second portion of the pressurized air, having thereby been heated, is injected into the exhaust gases proceeding toward the catalytic treatment device.

Abstract: An air pump includes a compressor having a compressor wheel mounted in a housing assembly defining an air inlet for leading air flow into the compressor wheel and defining a volute for receiving compressed air from the compressor wheel. A vaned diffuser ring is mounted within the housing assembly radially outward of the compressor wheel and includes an annular vane plate and a plurality of circumferentially spaced vanes having proximal ends rigidly attached to a first side of the plate, the vanes extending axially from the vane plate and distal ends of the vanes being disposed proximate a first wall of the housing assembly axially spaced from the plate such that a vaned diffuser passage is defined between said first wall and the vane plate. The vaned diffuser ring is embedded within the volute such that a second side of the vane plate is wetted by air within the volute.

The e-machine section includes an e-machine housing that houses at least part of the e-machine. The turbomachine further includes a coolant jacket that is defined at least partly in the e-machine housing. The coolant jacket is configured to receive a fluid coolant flow therein for cooling the e-machine.

Abstract: A single-stage compressor device includes a housing and a rotating group with a shaft and a compressor wheel. The compressor wheel includes a front face and a back face. The front face cooperates with the housing to define a compressor flow path. A motor drives rotation of the rotating group within the housing. Furthermore, the compressor device includes a bleed system fluidly connected to the compressor flow path and configured to receive bleed fluid from the compressor flow path. The bleed system includes a bleed passage. At least a portion of the bleed passage is cooperatively defined by the back face of the compressor wheel and an opposing surface of the housing. The bleed system is configured to pass bleed air from the bleed passage, thereby alleviating thrust loading of the compressor wheel on the rotating group.
