Abstract
Improvements in control devices, driven by level differences in liquids, especially liquid level sensitive device that responds to variations in the level of different portions of a liquid mass, characterized by comprising a movable wall, means that produce a signal in responsive to the position of the movable wall, two actionable air pumps to move the wall, the air pumps being connected to air exhaust ducts, each of which has an open lower end immersed in the liquid and a column of liquid in the lower terminal portion of the duct, the lower ends of the ducts being at the same level, each of the air pumps being continuously operated to force a stream of air bubbles through the liquid at the lower ends of the ducts of air exhaust, having the highest height of the liquid column contained in the exhaust duct of air submerged in the liquid portion a higher level that causes the air pump connected to it to increase the air pressure exerted by it to force air bubbles through the liquid and thus move the wall displaceable in one direction against pressure exerted by the other air pump.
