Abstract (en)
[origin: US6119283A] A method and apparatus for evacuation of liquids, such as wastewater from e.g. wash basins, urinals, bath tubs or showers, whereby the liquid is collected in a sump, generates a hydrostatic pressure and is evacuated from the sump through a vacuum pipeline after a predetermined hydrostatic pressure is generated. In order to avoid flexible control conduits and to achieve time controlled evacuation with a simple mechanism, valves are integrated in a housing and operated by pressure differences acting on diaphragms after a certain hydrostatic pressure has been generated. One of the valves opens a connection between the sump and the vacuum pipeline to evacuate the liquid.
