Method for Operating a Compressor Device and Associated Compressor Device

A method for operating a compressor device, comprising:

• providing an electric drive, a compressor chamber and a cooling chamber which adjoins the compressor chamber;
• enclosing the compressor chamber by a partition in the form of a tube which is provided between an electric stator of the electric drive and a rotor;
• and
• encapsulating the compressor chamber using the partition in relation to a cooling chamber,
• wherein the cooling chamber is part of a cooling device and comprises a cooling medium which may be transported out of and into the cooling chamber using a cooling circuit line,
• wherein the cooling medium serves for dissipating heat which develops primarily as a result of a stator section of the electric drive, and
• wherein during operation of the compressor device, a first pressure of the cooling medium in the cooling chamber is held above a second pressure of a compressor medium in the compressor chamber.
