Abstract

203,828. Fries, G., and Schneider, H. July 3, 1922. No Patent granted (Scaling fee not paid). Working-fluid supply; driving and transmitting mechanism, special applications of. - Relates to an internal-combustion turbine combination comprising two turbines connected to one another by a differential gear through the driven member of which power is transmitted. Fig. 2 shows one-half of the combination. The carrier b of the planet wheel c is furnished with a helically - toothed wheel d which drives an air compressor of the axially-sliding abutment type through a similar wheel e and spur wheels. The compressed air passes by a pipe m into a distributor comprising a cylinder o having spaced slots p and rotating in a cylinder q. The compressed air passes by pipes r to two valves s, each portion being then mixed with gaseous fuel and passed to an explosion chamber t having one end formed with a crown of guide vanes leading to the turbine wheel u. Between the guide vanes and the turbine wheel is inserted a disc valve w, with openings corresponding with the guide-vane openings, controlled by a piston 1 subjected to the pressure of the explosive chamber and the pressure of a spring. On igition of the gases the piston is driven up, causing the disc w to turn and allow the gases to flow across the turbine wheel. As the pressure falls the spring returns the piston to its lowest position. To use one turbine only of the combination, the bevel wheel 5 is stopped by means of a brake 7, 8. The number of revolutions of the carrier c is thereby reduced by one-half and the speed of the compressor correspondingly reduced. The explosion chamber is cooled by a cone 10 filled with water and by steam or water injected into the chamber by way of a valve 11.
