Free Metalworking Project Plans: The Flame Eater (Vacuum) Engine by Jan Ridders

Material: Steel and Brass

Back in February I posted plans for a Coffee Cup Stirling Engine by Jan Ridders, which have proved quite popular with more than 500 downloads to date.

Since the first engine went over so well with everyone, I thought it was about time for another. These plans are for a “Flame Eater” engine (AKA a Flame Sucker or Vacuum Engine).


The working principal is nicely illustrated by the animation below, but you really need to visit Jan’s site for the whole story on how this engine works, and what makes Jan’s design so special.flame-eater-principal

Here’s a short video of Jan’s Flame Eater in action:

If you decide to tackle this little engine, be sure to visit Jans site for lots great information on the theory, design, and construction of this great little engine.

Thanks Jan for contributing your plans!
