I found this in Tubal Cains you tube videos. It is a simple steam (or compressed air) engine. Since there is no wrist pin on the piston side of the connecting rod, it causes the cylinder to pivot. As the cylinder moves it opens and closes ports so there are no complicated valves. The piston is a close tolerance fit without any o-ring. When i first tried to run it, I had to use quite a bit of air pressure until the piston and cylinder wore in. Now it will run on 10 psi. Instead of coming up with some kind of small nipple to connect air to, I just hold the rubber tip of my air chuck up to the inlet hole. If you thought of trying to build working engine this is a good design to start with.
