PURPOSE:To aim at reduction in weight of a device, by simplifying it in structure, in case of the above-captioned device provided with a fuel tank, an oxidizer tank, a cooling passage, a combustion chamber, fuel pump-turbine and an oxidizer pump-turbine inside the combustion chamber. CONSTITUTION:At the time of driving a rocket or the like, fuel inside a fuel tank 4 is led into a cooler 13 by a fuel pump 10 via a pipe line 2, and gasified with heat energy out of a combustion chamber 16. A part of this gasified fuel is led into fuel turbine 12 via a flow control valve 14, making it do its work and, after this fuel pump 10 is rotated, it is fed to an injector part 15 together with the remaining gasified fuel. On the other hand, an oxidizer is led into an oxidizer pump 20 from a tank 5 via a pipe line 3 and gasified, and with its part, an oxidizer turbine 23 is driven whereby an impeller 22 of the said pump 20 is rotated and then it is led into the injector part 15. Then, the fuel and the oxidizer are made into a chemical reaction, through which kinetic energy is jetted out of a nozzle 17, thus securing a thrust.
