The movement of the piston causes the rotation shaft to rotate. Then, when the piston moves to the bottom dead center, the inertia of the rotation causes the piston to reversely move in the direction in which the volume of the combustion chamber is reduced. At this time, the exhaust valve is opened to exhaust the high-pressure gas from the combustion chamber so as not to hinder the movement of the piston. When the piston moves to top dead center, the inertia of rotation causes

Provided is a rotational force generation device characterized in that the rotational force is continuously output from the rotational shaft when supplied.

In the torque generating device according to the second aspect, the high pressure gas enters the internal space by opening the air supply valve, and the pressure causes the piston to move in a direction in which the volume of the internal space increases. The movement of the piston causes the rotation shaft to rotate. Then, when the piston moves to the bottom dead center, the inertia of the rotation causes the piston to reversely move in the direction in which the volume of the internal space is reduced. At this time, by opening the exhaust valve, the high pressure gas is exhausted from the internal space so as not to hinder the movement of the piston. When the piston moves to the top dead center, the inertia of the rotation causes the piston to reversely move in the direction in which the volume of the internal space increases. At this time, the air supply valve is opened and high-pressure gas is introduced into the internal space. By repeating this, the rotational force can be continuously output. The rotating force generator can be constructed by modifying the automobile engine, and does not require fuel for the automobile engine because it operates by burning wood chips and dust to generate steam as high-pressure gas.

And an exhaust valve opening / closing mechanism (4a, 4b, 4c) that opens the exhaust valve 4 for each exhaust period during which the piston 2 moves in the direction.

And a timing gear (not shown) that is transmitted to the.

The torque generating device 10 can be manufactured by modifying an obsolete 4-cycle engine such as an automobile or a tiller. There are two points to modify. (1) Since the original valve spring lacks the sealability against the pressure of high-pressure steam higher than the pressure of fuel gas,
Replace with valve springs 3a, 4a with enhanced spring force. (2) The cam shafts 3c and 4c are set to 1 for two rotations of the rotary shaft 5.
Since the original valve cam rotates the air supply valve 3 and the exhaust valve 4 only once every two rotations of the rotary shaft 5, the air supply valve 3 and the exhaust valve 4 are opened every one rotation of the rotary shaft 5.
