FIELD: engines and pumps.

SUBSTANCE: invention relates to machine building, primarily, to turbo-compressors used, for example, for supercharging internal combustion engines, namely, to the bearing assemblies. The proposed turbo-compressor incorporates a rotor running in plain bearing, its extensions accommodating the turbine and compressor wheels. The said plain bearings arranged in a floating non-rotary mono-sleeve fitted, with a backlash, in the bearing housing, the said sleeve being furnished with oil-feed channel and the said bearing housing being provided with cooling chambers and oil-drain hole.
