A simple slide valve is used, allowing steam to flow to one side of the piston and the other alternately, as driven by an arm coming off the flywheel attached to the engine’s output shaft.

This article was originally published with the title “ Improved Slide Valve for Steam Engines ” in Scientific American Magazine Vol. 13 No. 38 (May 1858), p. 304 doi:10.1038 ...

Condensation also pulls a fairly strong vacuum. At 100C, 1.3cc of steam condenses to about 1 cubic millimeter of water. Engines which use that kind of boost from a phase change are called ...

The cylinder of this engine requires no boring out, there is no piston, no slide or exhaust valve, and, in fact, no sliding friction—the friction of the journals excepted.

The boiler powers a vertical slide valve engine shafted to a flywheel, with a flyball governor. Ernst Plank founded his company in Nuremburg, Germany in 1866. The company was well known for ...
