173,443. Brander, A. Feb. 12, 1921. Working-fluid supply; circular-flow type; reversing; cooling parts; motor power plant.- Combustion products from explosion chambers n pass to the nozzles t for forward or reverse driving of the rotor d according to the position of the reversing valve t in the combustion chamber. The vanes a of the rotor d are formed with slots b cut to threequarters of the depth of vanes a, the slots in one row of vanes being staggered relatively to those in the next row. as shown in the exhaust passage c Fig. 2, to allow the gases to expand and to pass from vane to vane. Fig. 4, shows the valve-gear for the supply of the working fluid. Cam projections 1, 2 operate the lever f<1> and a quadrant x which controls the fuel pump p<11>, the valve t through the links w, w<1>, and a compressed-air valve o<2> through the links v, v<1>. The valve o<2> is arranged to open slightly before the nozzle t' is closed by valve t, and to close before valve t opens. For reversing, the links w, w<1> are moved to the position y and fixed by a spring catch w<2>. The cam projections 1, 2 are formed on one cam sheave i, Fig. 1, and the projections 3, 4, for the combustion chamber on the opposite side of the casing, are formed on a second sheave. These sheaves slide axially on the shaft k under the control of a governor h. There are two explosions in each combustion chamber per revolution of the rotor. The rotor d is cooled by water caused to enter through a conduit e and to pass out through a conduit f by an injector m which is provided with a hinged guide m<1>, Fig. 3, so as to operate in both directions. Cooling water is supplied to the spaces g in the casing and by the pipes r, Fig. 2, to the reversing-valve t which is made hollow. The water finally passes out by the pipes u. In the plant shown in Fig. 10, the exhaust from an internal-combustion turbine A as above described passes to a water-tube boiler E, the steam from which is led to a turbine C driving a compressor B which delivers air under pressure to a receiver D which in turn supplies the compressed air for the internal-combustion turbine A. The exhaust steam from the turbine C passes to a condenser F, the resulting water being used as cooling water in the turbine A after which it passes to the boiler E.
