Abstract
A back-pressure sealing system for a revolving compressor, comprising: a stator with an outlet on the upper side and a neck, surrounding the outlet; a separating part above the stator, separating a low-pressure zone around the stator from a high-pressure zone above the outlet and having a central opening around the neck; a connecting system between the upper and lower sides of the separating part; a first sealing device for sealing the neck of the stator against the central opening of the separating part; and a second sealing device for sealing the connecting system; wherein the back-pressure from the high-pressure zone is used to tighten the first and second sealing devices for a good sealing effect and thus good effectiveness of the compressor.
