The system for flushing a vacuum toilet contains a urinal basin having a drain, which is connected to a drain line, and a bypass line, into which the drain line discharges, and which is connectable via a suction valve to a vacuum system. By generating a main air current in the bypass line and a secondary air current in the drain line, a noise emission in the area of the urinal basin may be significantly reduced.

1. A system for flushing a vacuum toilet, comprising: a urinal basin having a drain, which is connected to a drain line, anda bypass line, which is connected via a suction valve to a vacuum system,wherein the drain line discharges into the bypass line upstream of the suction valve,wherein the bypass line is at a first end directly connected to the suction valve and wherein the drain line has a predetermined continuous inclination from the drain to the bypass line in order to transport waste material located therein in the direction of the bypass line to the suction valve because of gravity,wherein the bypass line is configured to provide a main air current therethrough to the vacuum system via the suction valve,wherein the drain line is configured to provide a second air current therethrough to the vacuum system via the suction valve, andwherein the second air current is smaller than the main air current, thereby reducing the noise developed at the drain due to the second airflow caused by the vacuum system. 2. The system of claim 1, wherein the bypass line is connected via a coupling to the drain line. 3. The system of claim 1, further comprising a flushing water supply, which feeds flushing water via a flushing valve into the urinal basin during a flushing procedure. 4. The system of claim 1, wherein the bypass line is connected at a second end to an odor trap. 5. The system of claim 4, wherein the second end of the bypass line has a noise damper. 6. The system of claim 3, further comprising a control unit, which activates the flushing valve and the suction valve. 7. The system of claim 6, wherein the flushing valve and the suction valve are activated by the control unit with a time delay. 8. The system of claim 7, wherein the flushing valve is activated earlier than the suction valve. 9. An aircraft comprising: a vacuum toilet; anda system for flushing the vacuum toilet comprising:a urinal basin having a drain, which is connected to a drain line, anda bypass line, which is connected via a suction valve to a vacuum system,wherein the drain line discharges into the bypass line upstream of the suction valve,wherein the bypass line is at a first end directly connected to the suction valve and wherein the drain line has a predetermined continuous inclination from the drain to the bypass line in order to transport waste material located therein in the direction of the bypass line to the suction valve because of gravity,wherein the bypass line is configured to provide a main air current therethrough to the vacuum system via the suction valve,wherein the drain line is configured to provide a second air current therethrough to the vacuum system via the suction valve, andwherein the second air current is smaller than the main air current, thereby reducing the noise developed at the drain due to the second airflow caused by the vacuum system. 10. The system of claim 1, wherein the pipe diameters, the pipe lengths, and the flow resistances of the drain line and the bypass line are configured such that the main airflow is greater than the second air current.
