Gamma Engine with Ross Yoke

The Kontax Nano Cannon high temperature Stirling engine features a compact and efficient Ross Yoke mechanism, and has an anodised aluminium construction with honeycomb brass fittings. The solid brass flywheel rim has integral balancing, allowing the engine to run at over 2000rpm on a tiny candle-sized flame. Stirling engines come in three main configurations, alpha, beta and gamma. This Nano Cannon engine is a gamma configuration, with a displacer inside the main chamber and a parallel power cylinder housing the power piston. The power cylinder is connected to the main chamber by a small tube.

How does it work?

Stirling engines work by cyclically heating and cooling the air inside the main chamber. As the air heats up it expands, and as it cools down it contracts. This expansion and contraction drives a small power piston which in turn drives the flywheel. The clever thing about Stirling engines is that the mechanism for cycling the heating and cooling of the air is built into the engine in the form of the displacer, which is driven by the flywheel and crank arrangement and moves the air from the warm side to the cool side and back again over and over.

Stirling engines are named after the inventor, Rev. Robert Stirling, who patented his idea in 1816.
