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: An e-charger includes a motor case that encases the motor and an outer housing that houses the motor case. 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: A compressor device includes a housing with a cavity. The compressor device includes a rotating group supported for rotation within the housing. The rotating group includes a shaft that supports a compressor wheel proximate a first end of the shaft. A second end of the shaft extends away from the compressor wheel through the cavity of the housing. The compressor device further includes a moisture evacuation system configured to remove airborne moisture from the compressor device. The moisture evacuation system includes a shaft passage extending through the second end of the shaft and a housing passage extending through an outer wall of the housing. The shaft passage is fluidly connected to the cavity. The housing passage is fluidly connected to the shaft passage. The moisture evacuation system is configured to direct the airborne moisture from the cavity, through the shaft passage, and out of the housing via the housing passage.

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: A turbomachine includes a fluid compressor section with a compressor wheel supported on a shaft and a compressor housing that houses the compressor wheel for rotation therein about an axis of rotation. The turbomachine also includes an e-machine section with an e-machine operatively connected to the shaft and configured to convert energy between the e-machine and the shaft as the shaft rotates. 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. Also, the turbomachine includes a turbulator insert member that is removably received within the coolant jacket and that sub-divides the coolant jacket for directing the fluid coolant flow through the coolant jacket.
