Some history and technical details. |
|||
|
A Vacuum motor, also named "Flame Gulper," is a hot-air
motor but not a Stirling engine .The principle is quite old. In 1758 Henry
Wood already was granted a patent. From the technical point of view it is an
atmospheric motor, because the outer air pressure does the work (comparable
to the first Ottomotor). The piston sucks the flame into the cylinder
through an open valve and heat the air inside. When the piston reaches the front dead centre, the valve opens again and the cycle starts again. A balance wheel overcomes both dead centres. Used as functioning motors for models, they are often built as stationary motors in horizontal and vertical versions and as single, double or multi-cylinders. They have been used for models of nostalgic tractors and rail vehicles very successfully. |
