The force sparing temperature changer operates through at least two air evacuated bellows. The relative positions of the chambers are such that the moving walls of the chambers face each other and transmit opposing vector forces to each other. This causes the movable walls of the bellows to settle in positions which are the result of the balance of opposing forces upon the walls. An outside reciprocal vector force upon the movable walls tips the balance of the opposing forces upon the movable walls and causes a reciprocal expansion and compression of each chamber. The bellows chambers contain a low boiling point liquid, such as water under a vacuum, which responds to the the expansion and compression of the chambers. The cooling effects of the expansion of the chambers upon the low boiling point liquid are separated from the heating effects of the compression of the chambers, by separate tubings and one way valves.
