Power machine driven by solar energy - produces motion by evaporation and condensation of vapour cycle

摘要

A liquid flows through a solar energy collector and is evaporated. The vapour rises into a vessel in which the press rises as the vapour accumulates. At a sufficient press. a valve in the hose of the vessel opens and admits the vapour into a lower water jacketed vessel. The vapour presses on a plate floating on top of a secondary liq. in the lower vessel. The secondary liq. is formed into a cylinder in which it moves a piston doing useful work. The primary vapour condenses in the water jacketed cylinder and flows back to the inlet of the solar collector. This allows the working piston to drop back and return the secondary liq. into the lower vessel.
