クを示す。(Prior Art) The output of a Stirling engine, which is an external combustion engine, is determined by the pressure within a working space filled with working gas. For example, when increasing the output of a Stirling engine, the working gas pressure within the working space is increased. A typical conventional example of such a Stirling engine output control device is shown in FIG. 2 (see Japanese Patent Laid-Open No. 46-23534). The working space 1 of the Stirling engine is connected via a check valve 2 to a compressor 3 by a maximum cycle pressure line 4. The line 4 has a pressure reducing valve 3. The working space 1 is also connected to the compressor 3 by a minimum cycle pressure line 7 via a check valve 6 . The line 7 has a pressure increase valve 8 . 9 indicates a high pressure tank.

１の支点１４の位置を変位させる働きをする。 The downstream side of the pressure increase valve 8 is connected to a feedback piston cylinder 10, and the piston within the cylinder 10 is connected to the end of an accelerator lever 11 via a rod. The accelerator lever 11 is connected to the increase/decrease valves 8 and 5.
The valve stems 12 and 13 face each other. The feedback piston cylinder 10 is connected to the lowest cycle pressure line 7.
The piston moves according to the pressure of the accelerator lever 1.
It functions to displace the position of the fulcrum 14 of 1.

を圧縮機３側に抜き減圧させる。 When increasing the output of the Stirling engine, the accelerator lever 11 is pushed to the left to open the pressure increase valve 8, and high-pressure working gas is supplied from the compressor 3 or tank 9 to the working space 1. Further, when lowering the output of the Stirling engine, the accelerator lever 11 is pushed to the right to open the pressure reducing valve 5, and the pressure in the working space 1 is released to the compressor 3 side to reduce the pressure.
（従来技術の問題点）
スターリング機関の作動ガスは、極めて高圧で
作動空間に封入される。このため、増減弁やフイ

調整を大まかにし、微調整ができない。(Problems with the Prior Art) The working gas of a Stirling engine is sealed in the working space at extremely high pressure. For this reason, the springs incorporated in the increase/decrease valve and the feedback piston cylinder have a considerably large spring constant in order to balance this high pressure working gas. For this reason, applying a large operating force to the operating lever will only roughly adjust the increase or decrease of the output, and will not allow fine adjustment.

Link levers 17 and 18 are pivotally supported on the valve stems 12 and 13 of the pressure increase and decrease valves 8 and 5 along the operating lever 11. Valve stems 12, 13 and link levers 17, 1

云い換えれば、前述したレバー比を仮りにとる
と、操作力は1/6となり、操作レバー１１に対す

ー１１の微動作も可能となる。 Suppose that the point of action 16 is placed between the grip portion 14 and the pivot point 15 of the operating lever 11, and the link lever 1
When the ratio of levers 7 and 18 is 3:1, the operating force W in one direction applied to the grip portion 14 of the operating lever 11 becomes a force of 2 W at the point of action 16 and acts on one of the link levers. Furthermore, since the lever ratio of the link levers is 3:1, it acts on the support point 19 or 20 of the link lever 17 or 18. That is,
The force applied to the valve stem 12 or 13 is 6W.
In other words, assuming the above lever ratio, the operating force will be 1/6, and the operating force on the operating lever 11 will be greatly reduced, making it possible to make small movements of the operating lever 11.

and the supporting points 19, 20 of the valve stems 12, 13 and the link levers 17, 18, but the supporting points 2
The same effect can be obtained even if the support points 1 and 22 are arranged outside the support points 19 and 20.

This ensures that even if an error occurs in the axial position of the pivot point due to the frictional resistance of the seal and sliding parts of the feedback piston cylinder, it will not have a negative effect on output control, allowing accurate output control. do.
