Abstract

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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 170 words
In a turbocompressor, comprising: a shaft, a compressor housing, a compressor rotor accommodated in said compressor housing and mounted on said shaft; a turbine rotor mounted on the same shaft with said compressor rotor; a gas intake housing for supplying hot gas to said turbine rotor, accommodated in said gas intake housing; a housing cooled by a fluid, for escape of spent gases from said turbine rotor; an improvement residing in that said cooled housing includes a load-carrying framework defined by two spaced flanges and by longitudinal rigid shaped thin-wall steel elements interconnecting said flanges and spaced from one another, the spaces between said shaped elements being filled with thin steel panels defining jointly with the said shaped elements the external wall of the housing, the internal wall of the housing being made in the form of a plain thin-wall trough-shaped steel sheet secured to said flanges and arranged so that a space is defined intermediate said internal wall and said external wall for circulation of a cooling fluid therethrough.
Claim 2
Dependent Claim 170 words
In a turbocompressor, comprising: a shaft, a compressor housing, a compressor rotor accommodated in said compressor housing and mounted on said shaft; a turbine rotor mounted on the same shaft with said compressor rotor; a gas intake housing for supplying hot gas to said turbine rotor, accommodated in said gas intake housing; a housing cooled by a fluid, for escape of spent gases from said turbine rotor; an improvement residing in that said cooled housing includes a load-carrying framework defined by two spaced flanges and by longitudinal rigid shaped thin-wall steel elements interconnecting said flanges and spaced from one another, the spaces between said shaped elements being filled with thin steel panels defining jointly with the said shaped elements the external wall of the housing, the internal wall of the housing being made in the form of a plain thin-wall trough-shaped steel sheet secured to said flanges and arranged so that a space is defined intermediate said internal wall and said external wall for circulation of a cooling fluid therethrough.
Claim 3
Dependent Claim 52 words
A turbocompressor as set forth in claim 1, including at least two interconnecting elements adapted to interconnect said plain thin-wall trough-shaped sheet defining the internal wall of the cooled housing with said thin steel panels defining said external wall of said housing, in two symmetrical areas with respect to a vertical plane.
Claim 4
Dependent Claim 30 words
A turbocompressor as set forth in claim 1, wherein said rigid longitudinal shaped thin-wall steel elements are substantially trough-shaped and have concave sides facing said internal wall of said housing.
Claim 5
Dependent Claim 30 words
A turbocompressor as set forth in claim 2, wherein said rigid longitudinal shaped thin-wall steel elements are substantially trough-shaped and have concave sides facing said internal wall of said housing.
