Beschreibung
Zusammenfassung:	The balancing and sealing piston for an integrated motor compressor comprising a balancing piston designed to be mounted on a shaft of the motor compressor to compensate for the differential pressure being applied to the wheels of a compression section of the motor compressor between the suction pressure and the discharge pressure, and a sealing device surrounding the balancing piston and designed to be mounted on the case of the motor compressor to render the compression section tight. It furthermore comprises a gas extraction port, the axial position of the extraction port being determined such that the pressure value of the extracted gas is equal to a predetermined value less than the value of the discharge pressure.
