がある。Conventional methods for controlling the output of a Stirling engine include a first method in which the average pressure of the working fluid is adjusted and a second method in which the volume of the working fluid is varied to reduce the pressure amplitude.
平均圧力を加減する第１の従来方法を第３〜４図を参照
して説明する。A first conventional method of adjusting the average pressure will be described with reference to FIGS. 3 and 4.

を蓄気槽０１に引戻す。In order to increase the output in FIG. 3, the supply valve 03 is opened and the high pressure gas in the storage tank 01 is added to the compressed gas 06. As a result, the average pressure of the Stirling engine increases, and the engine's p-vIvji
As shown in FIG. 4, the average pressure and torque increase from B to A. Also, to reduce the output, use the pressure reducing valve 04 in Figure 3.
i is opened and the compressor 02 pulls the working fluid in the compression space 06 back into the storage tank 01.

In the figure, the dead volumes 06 to 09 are sequentially opened through four solenoid valves 010t to increase the dead volume and lower the pressure amplitude from the full load C curve to the partial load 0 curve.The Stirling engine output This reduces the

可成複雑となり、いずれの場合も内燃機関と比べて応答
性が劣る欠点がある。In the Stirling engine, which is an external combustion engine, it is difficult to quickly control the output, and the first method of adjusting the average pressure has poor response when the load is reduced, and this response is limited by the capacity of the compressor. . Further, in the second method of completely adjusting the volume, the structure becomes considerably complicated, and in either case, there is a drawback that the response is inferior to that of an internal combustion engine.

る。A combined engine of a Stirling engine and a gas turbine according to the present invention includes a gas passage connecting a combustor of the Stirling engine and a gas inlet of a gas turbine, and a working gas and combustion gas of the Stirling engine are provided in the gas passage. It is characterized by the provision of a heater for heat exchange.

Therefore, the output of the Stirling engine can be controlled only by the fuel injection amount of the combustor and the operation of the pie A' valve, and the overall responsiveness of the engine can be improved.
以下、第１〜２図を参照し本発明の実施例について説明

い。FIG. 1 shows a first embodiment in which air is used as the working fluid of the Stirling engine. Although the Stirling engine shown in the figure is of a rhombic drive type, the effect of the present invention does not change even if the external combustion engine has another structural type.

れを加圧しその一部を燃焼器１にもどしている。In the figure, a = f are the basic components of a Stirling engine, where a is a disgrace, b is a piston,
C is a heater, d is a regenerator, e is a cooler, and f is a compression space. 1 to 5 are main components of the gas turbine, 1 is a combustor, 2 is a turbine, 3 is a compressor, 4 is a check valve, and 5 is a pi/4' valve. After the heater C is heated by the combustion gas generated from the combustor 1, the turbine 2 is further driven, and the compressor 3 on the same axis is rotated. This causes the compressor 3 to suck in air, pressurize it, and return a portion of it to the combustor 1.

ができる。The remaining pressurized air passes through the check valve 4 and enters the compression space f of the Stirling engine, thereby constantly supercharging and pressurizing the interior of the dead space. The output of the Stirling engine is adjusted by manipulating the amount of fuel injection, changing the turbine rotation speed of the target supercharger, and adjusting the boost pressure. If even faster response is required, it is necessary to adjust the opening degree of the pinose valve 5. In this way, the output can be controlled over a wide range by operating only the fuel injection amount and the piston valve 5. Alternatively, if the shaft of the turbine 2 is used to drive the shaft of the Stirling engine, the output of the gas turbine can be extracted as power.

気槽ｇにもどされる。The shaft of the gas turbine drives the compressor, pressurizes the working fluid, and constantly supercharges the compression space f of the Stirling engine. Output control is the same as when the working fluid is air, but in this case the pumped working fluid is returned to the gas storage tank g.

If thermal energy is used to drive a turbine, it can be recovered as output, improving the overall performance of the engine.
