Folded Steam Engine
This model steam engine is a modification of the Right-Angle Steam Engine. Like that engine, it illustrates how the motion of the valve and piston are 90 degrees out of phase with each other (for an explanation of what that means, see my page on the Right-Angle Steam Engine).
This design is one step closer to the design of real steam engines in that the valve is brought close to the cylinder, to minimize the length of the pipes that carry steam. For efficiency, these should be as short as possible.
Watch the model in action:
Your model will arrive attractively packaged with all the necessary parts (even a screwdriver). The kit screws together in about 15 minutes, and does not require any special model-building skills. A detailed, step-by-step assembly video is available on our instructions page.
