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: An e-charger includes a shaft supported for rotation about an axis. The e-charger also includes a compressor wheel that is attached to the shaft. The e-charger further includes an electric motor configured to drive the shaft and the compressor wheel in rotation. Also, the e-charger includes a housing that houses the electric motor and at least part of the shaft. Moreover, the e-charger includes a dampening system incorporated in the housing and configured to dampen loads transferring through the housing. The dampening system includes at least one solid-state dampener that is resiliently flexible, and the dampening system includes at least one fluid viscous dampener.
