COMPRESSOR WITH AXIAL INLET Russian patent published in 2019 - IPC F04D29/00 

FIELD: machine building.

SUBSTANCE: invention relates to the field of compressor building, namely to centrifugal compressors with axial inlet. Compressor with axial inlet includes housing, front cover with axial suction branch pipe, rear cover, fairing, rotor shaft installed in support and thrust bearings, and flow part arranged in housing. Fairing is made in form of shell located inside front cover, enclosing rotor shaft front part installed in support bearing, at that, inlet annular cavity of profiled lengthwise section is formed between outer surface of fairing and inner surface of front cover, while fairing is secured to front cover by posts arranged along perimeter.

EFFECT: proposed technical solution allows increasing pressure ratio in compressor and reducing unbalanced axial force acting on rotor at starts and stops under excessive pressure.
