The disclosed technology generally relates to a compressor housing, comprising a first portion configured to house a compressor motor of a centrifugal compressor, a second portion configured to house an inlet housing of the centrifugal compressor, where the inlet housing is configured to receive refrigerant into an impeller assembly of the centrifugal compressor, and at least one refrigerant accumulator upstream of the second portion, the at least one refrigerant accumulator configured to accumulate liquid refrigerant.

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.

A compressor system includes an electric motor having a rotatable output shaft extending from either end thereof. The compressor system further includes multiple compression stages fluidly coupled to one another in series and mechanically connected to the output shaft. The first compressor stage includes two split impellers with each impeller discharging approximately one half of the fluid flow at a desired pressure to the second compressor stage.

A centrifugal compressor includes a motor cooling passage through which cooling fluid for cooling an electric motor flows, an air passage through which cooling air for cooling a first air bearing and a second air bearing is supplied to each of the first air bearing and the second air bearing, and a heat exchanger cooling the cooling air. The motor cooling passage includes a plurality of cooling axial passages having a first cooling axial passage through which the cooling fluid is supplied to the heat exchanger and a second cooling axial passage through which the cooling fluid is discharged from the heat exchanger. The heat exchanger has a first port communicating with the first cooling axial passage, a second port communicating with the second cooling axial passage, and a third port communicating with an air axial passage extending in an axial direction of a rotary shaft.

A compressor wheel arrangement for an electrically powered turbocharger, which can be connected with a rotor shaft of the turbocharger, having a compressor wheel made of a first metallic material, a shaft made of a second metallic material, which is tightly connected with the compressor wheel, at least one permanent magnet, which is non-rotatably arranged on the section of the shaft, in a ring-shaped area around a section of the shaft that extends behind the compressor wheel, between a casing and the shaft.

A blower motor is provided and includes a support assembly provided with a first stop step surface, a stator assembly disposed in the support assembly, a rotor assembly disposed in the stator assembly and an end cover disposed on the stator assembly and abutted against the support assembly and provided with a second stop step surface. The rotor assembly includes a rotating shaft and two ends of the rotating shaft are respectively provided with a first bearing and a second bearing. A resilient gasket is provided on one of the first stop step surface and the second stop step surface. The bearings are positioned by springs and cooperate with the resilient gasket to apply a tightening force to the bearings, which can reduce clearances in the bearings and effectively prevent balls in the bearings from making noise under a high-frequency vibration.

A centrifugal compressor that includes: a rotary shaft; a compressor impeller mounted on the rotary shaft and configured to rotate together with the rotary shaft to compress a fluid; a housing accommodating the rotary shaft and the compressor impeller; and a thrust bearing supporting the rotary shaft in a thrust direction such that the rotary shaft is rotatable. The housing includes: an impeller chamber in which the compressor impeller is accommodated; a thrust bearing accommodation chamber in which the thrust bearing is accommodated; and a partition wall separating the impeller chamber from the thrust bearing accommodation chamber. The partition wall has therein a cooling gas passage through which cooling gas flows to cool the thrust bearing and a cooling water passage through which cooling water flows to cool the partition wall.
