Abstract: A vacuum toilet comprising a bowl with flushing nozzles, a shut-off valve and a waste pipe. Connected in the lower region of the bowl is a pipe (12) which leads from the latter upwards and terminates open at a level (H2) slightly below the flushing nozzles (11).

Abstract: A device for controlling the operation of a vacuum toilet has a control computer integrated below the toilet seat, timecontrolledunits such as vacuum and compressed air generators with their corresponding closing and opening valves, and sensors for temperature, pressure and flow. An accessory control appliance or hand terminal is connectable to the control computer by a standardised interface, may control all required functions in parallel with the control computer, and allows manual input of the operation parameters. Device is also provided for outputting the content of a control device storage unit integrated into the control computer and storing over any time period the values for the operations effected.

Abstract: A discharge system for discharging wastes from a unit producing such wastes, such as a toilet, is disclosed. The system includes a device for creating a partial vacuum, an intermediate container and a collecting basin connected together by pipelines and valves in an arrangement which permits the use of an immediate container having a relatively small volume thereby permitting the use of a smaller vacuum pump. The discharge system is particularly useful for rail-bound vehicles and overland buses.
