FIELD: machine building. ^ SUBSTANCE: turbo-expander set consists of power external case and of internal case wherein there is installed shaft common for compressor and turbine steps. The power external case with elements of internal case whereon there are secured radial and axial supports of the shaft forms four successively arranged chambers: a chamber of gas outlet from the compressor, a chamber of gas inlet into the compressor, a chamber of gas inlet into a turbine and a chamber of gas outlet from the turbine. Axis of the shaft coincides with boring axis of the power case and is arranged vertically. The power external case is made as a single unit forming a cavity closed with a cover in its upper part. The chamber of gas outlet of the compressor step is located directly under the said cover. ^ EFFECT: raised efficiency and operability of set. ^ 2 dwg |
