Abstract: A turbocompressor which comprises a compressor housing receiving therein the rotor of the compressor, a gas intake housing adapted to direct a hot gas to the rotor of the turbine. The rotor of the turbine is mounted on the same shaft with the rotor of the compressor. The turbocompressor further comprises a housing cooled by a fluid, for example water, for escape of exhaust gases from the turbine, comprising a load-carrying framework formed by two spaced flanges and rigid longitudinal thin-walled shaped steel elements spaced from one another and interconnecting the flanges. The spaces between the elements are filled with thin steel panels defining jointly with the shaped elements the external wall of the housing. The internal wall of the cooled housing is made in the form of a plain thin-walled trough-shaped steel sheet secured to the flanges and arranged so that a space for circulation of the cooling fluid is afforded between the external and internal walls of the housing.
