ABSTRACT:
An external-combustion heat engine pump, one version consisting of four chambers, one liquid and one gas pumping chamber, a gas heating chamber and a gas cooling chamber. The two pumping chambers are connected by two tubes, one near the bottom of the chambers and one at the top of the chambers. The liquid pumping chamber, which contains a cycling container, is connected to a reservoir with tubing and a one way valve allowing liquid to enter. The gas pumping chamber is fitted with a bellows, which rises or falls as determined by the location of the cycling container. Gas enters the bellows through a one way valve connected to the bellows with tubing. The bellows is also connected to the heating chamber with tubing and with a one way gas valve which allows gas to enter this chamber. In operation, with the cycling container resting on the bottom of the liquid pumping chamber and the bellows contracted, the gas within the system is being heated (by any practical means) in the heating chamber, the resultant pressure build-up in turn force's liquid out of the two pumping chambers and out of the cycling container tube. As the liquid level drops the bellows expands, its pressure drops and gas flows into it from the cooling chamber. When the chambers's liquid reaches a predetermined level, the pressurized gas is released to the atmosphere through the cycling container tube, liquid from the reservoir refills the two pumping chambers, as they refill the bellows contracts forcing cool gas into the heating chamber now open to the atmosphere. When the pumping chambers refill, the cycling container sinks and the cycle repeats.
