摘要

The vertical outflow pipe conduit vacates water fed from a water-impenetrable surface and based on a filling of its capacity a suction effect is produced by the falling water flow. In the cover surface of the pipe is an aperture (9). A first pipe section (1) with a first free cross-section, issues into a second pipe section (3) with a second free cross-section, which is greater than the first free cross-section.
