Beskrivelse

BeskrivelseNewcomen6325.png	English: Atmospheric Steam Engine. The Steam was generated in the boiler A. The piston P moved in a cylinder B. When the valve V was opened, the steam pushed up the piston. At the top of the stroke, the valve was closed, the valve V' was opened, and a jet of cold water from the tank C was injected into the cylinder, thus condensing the steam and reducing the pressure under the piston. The atmospheric pressure above then pushed the piston down again. Deutsch: Atmospherische Dampfmaschine. Der Dampf wurde im Boiler A erzeugt. Der Kolben P bewegt sich im Zylinder B. Wenn das Ventil V geöffnet wird, strömt der Dampf in den Zylinder und drückt den Kolben nach oben. In der Spitze der Auslenkung des Kolbens wird das Ventil V geschlossen und das Ventil V' geöffnet, wodurch ein kalter Wasserstrahl aus dem Tank C in den Zylinder eingespritzt wird. Hierdurch kondensiert der Dampf und der Druck unter dem Kolben reduziert sich. Der atmosphärische Druck über dem Kolben drückt diesen nach unten.
