Motor-driven compressor having a compression section mounted on a free end of a cantilvered shaft

A motor-driven compressor with multiple compression sections, the motor-driven compressor comprising:

• a housing;
• a first compression drive shaft and a second compression drive shaft, both being rotatably supported in the housing by bearings comprising a first pair of bearings on the first compression shaft and a second pair of bearings on the second compression drive shaft;
• a flexible coupling device connecting the first compression drive shaft and the second compression drive shaft;
• an electric motor mounted on the first compression shaft between the first pair of bearings;
• at least two compression sections comprising a first compression section that is cantilevered at a free end of the first compression shaft, and a second compression section that is mounted between the second pair of bearings on the second compression shaft;
• a first thrust abutment mounted on the first compression shaft between one of the first pair of bearings and the flexible coupling device;
• and
• a second thrust abutment mounted on the second compression shaft between one of the second pair of bearings and the second compression section.
