Nachteilig bei der bekannten Maschine ist jedoch, dass der Wirkungsgrad sehr begrenzt ist. Beispielsweise wird innerhalb des Zylinders befindliche Luft bei der Bewegung vom unteren zum oberen Totpunkt komprimiert. Zudem ist die Steuerung der Druckluft in den Zylinder sehr unflexibel.A disadvantage of the known machine, however, that the efficiency is very limited. For example, air inside the cylinder is compressed as it moves from bottom to top dead center. In addition, the control of the compressed air in the cylinder is very inflexible.
