ABSTRACT OF THE DISCLOSURE
A system for generating power in a variable volume engine using a
liquid solvent and a soluble gas. Power is generated by decreasing the
pressure within one or more variable volume chambers through the solution
of ammonia in water when each chamber is at or near a maximum volume. The
resulting differential between the atmospheric pressure and the reduced
pressure within the chamber is used to generate mechanical power. The
ammonia and water is mixed in a tank at a remote location from the piston
and cylinder. The cylinder is operatively connected with the tank such that
the vacuum developed in the tank may be employed within the cylinder for the
production of power.
