The chapter presents the main principle on which the proposals of this book are based. In this principle, the energetic efficiency of pneumatic actuators is strongly increased by adding an amount of expansion work to the classical work produced by constant pressure displacement. Such a principle has already been applied in steam machines at the beginning of the 20th century or in existing pneumatic converters used as motors for automotive vehicles.

Keywords: Constant Pressure Displacement Work, Expansion Work, The Truglia Motor, Compressed Air Car.
