FIELD: mechanical engineering; liquid and gas transfer facilities.
SUBSTANCE: proposed pump-compressor contains cylindrical stator with inlet and outlet pipelines, rotor with spiral diaphragm, drive connected with shaft of rotor and installed in eccentricity housings, casing arranged between rotor and stator whose inner surface is in constant contact with outer edge of diaphragm. Spiral diaphragm is made conical and elastic. Shaft of rotor is installed in eccentricity housing for turning the housings in holes of stator and fixing in two opposite positions in plane of inlet and outlet. Casing is made rotating, being freely arranged on bearing.
EFFECT: enlarged sphere of application, simplified design.
