A vacuum toilet system comprises a waste-receiving bowl having an outlet, a sewer pipe that can be placed at a pressure that is lower than that in the interior of the waste-receiving bowl, and a discharge valve connected between the sewer pipe and the outlet of the waste-receiving bowl for controlling passage of material from the waste-receiving bowl to the sewer pipe. The discharge valve comprises a valve housing and a closure member. The closure member is movable relative to the valve housing between an pen position and a closed position. A drive mechanism is connected to the closure member for bringing about movement thereof relative to the valve housing. A sensing device provides a control signal in the event that the drive mechanism is not able to cause the closure member to attain its closed position. A control device is connected to the drive mechanism and responds to a user stimulus by causing the drive mechanism to move the closure member from its closed position to its open position and subsequently from its open position towards its closed position. The control device responds to a control signal provided by the sensing device by causing the drive mechanism to move the closure member towards its open position and subsequently towards its closed position.

A vacuum toilet system comprising a waste-receiving bowl defining an interior space for receiving waste material and having an outlet, a sewer pipe defining an interior space that can be placed at a pressure that is lower than that in the interior space of the waste-receiving bowl, and a discharge valve connected between the sewer pipe and the outlet of the waste-receiving bowl for controlling passage of material between the waste-receiving bowl and the sewer pipe, said discharge valve comprising valve portions that are movable selectively relative to one another between an open position in which the valve is open and a closed position in which the valve is closed, and a drive mechanism that acts on at least one of said valve portions for bringing about relative movement of said valve portions, and the system further comprising sensor means for sensing whether the drive mechanism is able to bring the valve portions to the closed position and providing a control signal in the event that the drive mechanism is unable to cause the valve portions to attain the closed position, a control device which is connected to the drive mechanism and responds to a user stimulus when the valve portions are in the closed position by causing the drive mechanism to bring the valve portions to the open position and subsequently causing the drive mechanism to bring the valve portions towards the closed position, the control device responding to said control signal by causing the drive mechanism to bring the valve portions towards the open position and subsequently towards the closed position.
