ABSTRACT:
A vacuum toilet system comprises a tank having a sewage inlet connection for entry of sewage into the tank, a level detector establishing a maximum filling level for the tank, and a spray nozzle assembly for distributing cleaning liquid inside the tank. The spray nozzle assembly comprises an axle member having a first end portion provided with a mechanism attaching the axle member to the tank and a second end portion defining a vertical axis of rotation. The axle member is hollow and defines a passage that extends from the first end portion of the axle member and debouches at an outlet at the second end portion thereof. The spray nozzle assembly comprises a spray head mounted on the second end portion of the axle member for rotation about the vertical axis of rotation. The spray head is located above the maximum filling level of the tank and comprises a nozzle body that defines a nozzle that is connected to the outlet of the passage in the axle member and rotates about both the vertical axis and a horizontal axis to provide a three-dimensional spray pattern of cleaning liquid inside the tank.
