  • Fluid compressor device with e-machine and plural working fluid flow paths for e-machine and bearing cooling
    Patent number: 12372100
    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.
