Descrição
I highly recommend watching the video for more details: https://www.youtube.com/watch?v=z3x-_-5T9DQ&t=16s
This is an air engine with a nutating disk. It runs on compressed air and starts operating at around 10 psi. A big advantage is that it doesn't have any valves, pistons, or cranks. However, you might face a few challenges during the build that I didn't show in the video.
After you've finished assembling, make sure the output shaft rotates freely and that the disk nutates without getting stuck or rubbing against anything. If there's any jamming, check the clearance between the partition in the engine block-A and the disks—this might require some extra sanding (I had to sand quite a bit, as you can see in the video).
Second, before attaching the top disk, you'll need to secure the bushing with a small ring called a bushing lock. Make sure this is fastened well because it shouldn’t move when you apply air pressure. I wrapped some tape around it first and then slid the bushing lock tightly over it, and that worked great for me. (It won’t be an issue if it shifts when the engine isn’t under pressure, but once you apply air, if it’s not locked down properly, the disk will get stuck.)
Another thing is the thin ring called "unnamed." You can glue it in place during assembly. I added this part intentionally after making sure everything was aligned and working smoothly, and it's definitely necessary.
Finally, after assembling the engine block with M2 bolts, if the holes for the gasket covers on the top and bottom don’t align, you can sand the edges of the engine block. Just make sure to take your time and be careful not to cause any jamming with the disk.
The gasket drawing is available in the files as a 1:1 scale. You can print it directly.
