Description: 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.
