Abstract
An automatic drinking-trough which can only be used by animals for drinking purposes has a pressurized water duct the aperture of which is closed by a valve. The opening of the valve is controlled by a tube displaceable in all directions. The valve is arranged under a hood situated above the bowl, with the end of the control tube protruding vertically below the hood and in the bottom of the bowl. Thus the animal has to drive its snout down to the bottom of the bowl in order to reach the tube and cannot tamper with it inadvertably or playfully.
