ABSTRACT:
The low pressure engine operates through a temperature and pressure differential between two chambers containing a low boiling point liquid. The pressure differential causes the liquid to rise in a relatively small interspace between a conduit and a float in the relatively warm chamber. In order to obtain a mechanical advantage the float is temporarily restricted from responding to the buoyant force exerted by the liquid until the liquid in the interspace has reached a predetermined level.
