Newcomen Atmospheric Engine, 1712
Bildnummer 12652230
| The atmospheric engine was invented by Thomas Newcomen in 1712, and is often referred to simply as a Newcomen engine. It was the first practical device to harness steam to produce mechanical work. Newcomen engines were used throughout Britain and Europe, principally to pump water out of mines. Hundreds were constructed through the 18th century. How it worked: Steam was generated in the boiler (A). The piston (P) moved in the cylinder (B). When valve V was opened, steam pushed up the piston. At the top of the stroke, the valve was closed, valve V' was opened, and a jet of cold water from the tank (C) was injected into the cylinder, condensing the steam and reducing the pressure under the piston. The atmospheric pressure above then pushed the piston down again. | |
