A vacuum toilet (10) which discharges the wastewater into a wastewater tank (60) via an inlet valve (30), an intermediate tank (40) and an outlet valve (50), wherein, for flushing purposes, a vacuum is generated in the intermediate tank (40), with the inlet valve (30) and outlet valve (50) closed, and then the inlet valve (30) is opened, as a result of which the wastewater is sucked out of the toilet bowl (10) into the intermediate tank (40). Thereafter, the inlet valve (30) is closed again and the intermediate tank (40) is subjected to pressure. Once the outlet valve (50) has been opened, the wastewater is forced into the wastewater tank (60) by the positive pressure. The toilet (10) is distinguished in that, following completion of a flushing operation, the state produced is one in which alternately just one of the two valves (30, 50) has been closed, as a result of which the service life of the valves is extended. |
