1. A system for flushing a vacuum toilet, comprising:
a flushing water reservoir container,
a toilet bowl, and
a spray device,
wherein the flushing water reservoir container is fillable with flushing water;
wherein thee toilet bowl is connectable via a vacuum wastewater line and via a flushing valve to a vacuum system, and
wherein the spray device arranged in the toilet bowl is connected to the flushing water reservoir container wherein a partial vacuum is generated in the vacuum wastewater line upon opening of the flushing valve which generates an airflow by which the 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.
2. The system of claim 1, further comprising a toilet cover which closes the toilet bowl airtight during the flushing procedure.
3. The system of claim 2, wherein the toilet cover is closed by a pneumatic cylinder which is impinged by partial vacuum and, in addition, is aerated by ambient air.
4. The system of claim 3, wherein the pneumatic cylinder is controlled by a solenoid valve which alternately opens and closes the operating media of partial vacuum and ambient pressure.
5. The system of claim 2, wherein the toilet cover rests on a toilet seat during the flushing procedure.
6. The system of claim 5, wherein the toilet cover comprises a cleaning device for cleaning the toilet seat.
7. The system of claim 6, wherein the cleaning device has a cleaning sponge and a drive which moves the cleaning sponge over the surface of the toilet seat.
8. The system of claim 7, wherein the drive is a rotational drive situated concentrically to the toilet cover and toilet seat.
9. The system of claim 8, wherein the toilet cover and the toilet seat are circular.
10. A toilet cover comprising a cleaning device which has a cleaning sponge and a drive which moves the cleaning sponge over the upper surface of a toilet seat to be cleaned.
11. The toilet cover of claim 10, wherein the drive is a rotational drive situated concentrically to the toilet cover and toilet seat.
12. The toilet cover of claim 10, wherein the toilet cover and the toilet seat to be cleaned are circular.

The claims below are in addition to those above.
