- fresh water must be transported out of a fresh water tank by means of compressed air to supply, for example, a hand basin with water and the wastewater are removed from the hand basin by means of a vacuum again.
- control processes can be controlled by a vacuum source and compressed air source are provided and from this vacuum source and this compressed air source by controlling electrically operated valve units with a corresponding electronic control unit at certain intervals, the compressed air and the vacuum of such kind on reservoir, intermediate container or waste container is abandoned in that the desired conveying effects for the fresh water, the rinsing water or the wastewater are thereby achieved.
- a disadvantage of such solutions is that for the operation of such a control device both compressed air and vacuum and electrical energy must be available. This makes the connection of such a sanitary device expensive, which is particularly evident is part, if the sanitary device to be installed on board of vehicles such as rail vehicles.
- the invention has for its object to provide such a control unit, with both the installation and the operation of such a sanitary device can be simplified.
- valve control device of the type described above, in which a coupled to the valve tappet compressed air valve unit with a valve body which blocks in the first position of the valve stem to the housing a compressed air input to a compressed air outlet, and in the second position of the valve stem to the housing provides a connection between the compressed air inlet to the compressed air outlet, is provided.

In this case, the transport of the fresh water or rinse water or wastewater can take place both by means of compressed air and by means of a vacuum in the sanitary device. According to the invention, only one compressed air source is required for this control by means of the control valve device.

At its lower end 20b, the valve stem 20 also protrudes from the valve housing 10 and is at this lower end with an axial longitudinal bore 22 provided. The axial longitudinal bore 22 is surrounded by a ring magnet 30 at the lower end 20b of the valve lifter.
- the valve housing 10 encloses an interior, which is divided by a first seal 41 and a second seal 42 a total of three chambers. Starting from the upper end 20 a of the valve stem, a vacuum chamber 1 1 is bounded by the housing and the first, attached to the valve stem seal 41. This vacuum chamber 1 1 is connected by a first vacuum line connection 12 to a vacuum line 12 a.

- valve stem is pressed downwards via the actuating element 21 from the first, upper position into a second, lower position, then the magnet 30 is moved closer to the ferromagnetic valve body 61 and the magnetic force of the magnet on the ferromagnetic valve body 61 is thereby increased.
- This increase causes a lifting of the valve body 61 from the closed position shown in Figure 1 against the spring force of the second coil spring 63 in a raised, open position. In this raised, open position, the flow through the compressed air line 60 is released from a compressed air inlet 83 to a compressed air outlet 84.
