497,188. Elastic fluid turbines. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES. March 22, 1938, No. 8769. Convention date, March 25, 1937. [Class 110 (iii)] [Also in Group XXVII] The exhaust gases from an internal-combustion engine 1 actuate two turbines 4, 7 connected in series and each turbine drives a turbo blower 11, 9 supplying scavenging and supercharging air to the engine. The turbo blowers are also connected in series and from a pipe 10 connecting them air may be passed through a valve 14 to the inlet chamber of the second turbine 7. The first turbine may be connected by gearing to the engine shaft. Regulation of the second turbine may be effected by varying the area of its nozzle chamber. |
