Abstract: The integrated expander and motor-compressor assembly (2) comprises a compression section (9) mounted between the two radial bearings (15, 16) on a transmission shaft (10), an expander (30) cantilevered at a free end of the transmission shaft, a gas diffuser (33) and a duct (34) between the expander and a first radial bearing (16), 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.

Abstract: A compressor unit (25) is disclosed comprising at least a first motor driving in rotation at least one impeller (4) of a compression stage, having at the outlet of the impeller (4) a diffuser (23) designed to centrifugally channel the gases coming from the impeller (4), and having a centripetal return channel (24) downstream of the diffuser (23).The return channel (24) includes at least one movable blade portion (21) that, when moved, can vary a tangential component of the speed of the gases coming from the return channel (24).
