PCT No. PCT/DE91/00924 Sec. 371 Date Jul. 21, 1993 Sec. 102(e) Date Jul. 21, 1993 PCT Filed Nov. 19, 1991 PCT Pub. No. WO92/09808 PCT Pub. Date Jun. 11, 1992.The invention concerns a jet compressor for gaseous media for use in metallurgical or chemical processes having a driving nozzle which is arranged centrically in a jet head and directed toward a mixing chamber with which a diffuser is connected coaxially. In order to avoid the conventional disadvantages and provide a jet compressor which is simple in design and as compact as possible and to achieve improved efficiency and pressure ratios in comparison to jet devices of the same scale while operating in a reliable manner, it is proposed that the driving nozzle (10) be a ring jet nozzle having a conical central body (12) which narrows in diameter conically toward the mixing chamber (31) of the nozzle (30). |
