RADICAL COMPRESSOR'S AXIAL BEARER UNLOADING UNIT WITH THE OPERATING WHEEL ARRANGEMENT "BACK TO BACK" Russian patent published in 2012 - IPC F04D29/05 F04D29/51 F04D17/08 

FIELD: mechanics.

SUBSTANCE: device refers to compressing and can be used in radial compressors primarily in the bi-sectional ones with the wheel arrangement "back to back" and providing the quick control of the axial force and reducing the load on the axial bearers. Axial bearer's unloading unit of the bi-sectional radial compressor, including the unloading device as a dummy piston located between compressor's sections and high-low pressure sections, formed by the walls of the unloading device and the compressor's operating wheels , installed on the rotor, in that, the mentioned low-pressure section communicates with low-pressure section from the suction side through a throttling device, done with the ability to change its flow passage at the rotor's axes displacement.

EFFECT: quick control of the axial force and reducing the load on the axial bearers.
