Abstract

A system for flushing a vacuum toilet contains a flushing water reservoir container, which may be filled with flushing water, a toilet bowl, which is connectable using a vacuum wastewater line and via a flushing valve to a vacuum system, and a spray device, situated in the toilet bowl, which is connected via a Venturi nozzle to the flushing water reservoir container. A partial vacuum is generated in the vacuum wastewater line when the flushing valve is open, which generates an airflow, by which flushing water contained in the flushing water reservoir container is suctioned, sprayed via the spray device into the toilet bowl, and suctioned into the vacuum wastewater line.
