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.

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.
