The integrated expander and motor-compressor assembly comprises a compression section mounted between the two radial bearings on a trans-mission shaft, an expander cantilevered at a free end of the transmission shaft, a gas diffuser and a duct between the expander and a first radial bearing, the first radial bearing been the closest radial bearing to the expander. The gas diffuser diffuses a gas barrier which is sucked up by the duct.

Integrated expander and motor-compressor assembly and closed loop cooling circuit comprising such an assembly

A balancing and sealing piston system for an integrated motor compressor is described. The system comprises a balancing piston designed to be mounted on a shaft of a motor compressor to compensate for the differential pressure applied to the impellers of the compression section of the motor compressor, and a sealing device surrounding the balancing piston and designed to be mounted on a case of the motor compressor to seal part of the compression section. The system further comprises a gas extraction port, the axial position of which is determined such that the pressure value of extracted gas is equal to a predetermined value that is less than the value of the discharge pressure.

The bundle compressor to a bundle motor for compressor unit compressor unit includes one at fastening device configured to fasten the compressor bundle to a motor casing of the motor compressor unit, and also includes at least one opening sized to couple a motor rotor and a compressor rotor through the at least one opening.

Integrated motor-compressor with a stand-alone motor and bundle

A motor-driven compressor equipped with multiple compression sections, the motor-driven compressor including, at least one housing, at least two drive shafts, the at least two drive shafts being rotatably supported in the housing by at least two bearings, a flexible coupling device connecting the drive shafts, an electric motor mounted on a first compression shaft of the at least two drive shafts, and at least two compression sections. A first compression section of the at least two compression sections is cantilevered at a free end of a first compression shaft of the at least two drive shafts, and a second compression section is mounted between two bearings on a second compression shaft of the at least two drive shafts.
