Abstract

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.
