Une gravure ancienne montrant la machine à vapeur à simple effet Watt des années 1700 Il est tiré d'un livre de génie mécanique victorien des années 1880 Le moteur Watt, également connu sous le nom de Boulton et Watt machine à vapeur, était un des premiers moteurs. James Watt a développé le design de 1763 à 1775 avec le soutien de Matthew Boulton. La conception a permis d'économiser beaucoup plus de carburant par rapport aux conceptions antérieures. Watt a équipé le moteur d’une chambre de condensation séparée ou « condenseur » (au centre de cette gravure). Le condenseur est resté froid et sous la pression atmosphérique en tout temps, tandis que la bouteille est restée chaude.

An old engraving showing the Watt single-acting steam engine of the 1700s. It is from a Victorian mechanical engineering book of the 1880s. The Watt engine, alternatively known as the Boulton and Watt steam engine, was an early engine and was one of the driving forces of the Industrial Revolution. James Watt developed the design from 1763 to 1775 with support from Matthew Boulton. Watt’s design saved so much more fuel compared with earlier designs that they were licensed based on the amount of fuel they would save. Watt's design became synonymous with steam engines, and it was many years before significantly new designs began to replace the basic Watt design. The first steam engines, introduced by Thomas Newcomen in 1712, were of the ‘atmospheric’ design. At the end of the power stroke, the weight of the object being moved by the engine, pulled the piston to the top of the cylinder, as steam was introduced. Then the cylinder was cooled by a spray of water, which caused the steam to condense, forming a partial vacuum in the cylinder. Atmospheric pressure on the top of the piston pushed it down, lifting the work object. Watt equipped the engine with a separate condensation chamber or ‘condenser’ (centre in this engraving). Because the condenser and the working cylinder were separate, condensation occurred without significant loss of heat from the cylinder. The condenser remained cold and below atmospheric pressure at all times, while the cylinder remained hot at all times. Watt never ceased developing the steam engine, introducing double-acting designs (with two cylinders) and various systems for taking off rotary power.
