Abstract

The device used as a hydraulic pump brings the water from one level to a higher one without excessive pressure build-up. It has water conveying pipes welded to it and mechanical means to draw the air into the system. Its main advantage is the very little effort required from the operator to draw water from a deep well, for example, and the ease with which it may be carried to be used on the spot. The device may be formed by a container to which are connected water pipes and a hollow and balanced rod through which air is taken in.
