Embodiment Construction

[0066] As can be seen from the figures, the vacuum toilet system includes a bedpan 10 having a bedpan drain 11 .

[0067] The bedpan drain 11 is connected to the transfer box 20 by means of a bedpan drain line 12 . A bedpan drain valve 13 is inserted into this bedpan drain line and is arranged close to the transfer tank 20 . It is generally understood that a single bedpan drain valve may be used as shown. However, in other applications, two valves may be inserted in the bedpan drain line, one valve close to the bedpan outlet and one valve close to the transfer tank inlet. This provides sufficient safety against leaks and back pressure.

[0068] The bedpan drain line is connected to the transfer box at a certain level close to the upper end of the transfer box. The transfer tank drain 21 is arranged at the bottom of the transfer tank and is connected to the waste water tank 30 by means of the transfer drain line 22 . The relay drain valve 23 is inserted into the relay drain...
