ABSTRACT:
Water dispenser, which comprises, in addition to a water container, a filter element contained within a filter housing having an inlet and a dispensing outlet, a source of pressure and first valve and first conduit means for feeding water from the container to the filter housing inlet; means for feeding gas to the filter inlet to create gas pressure at the inlet, consisting of a reservoir, and the control means comprise the third conduit and valve means for permitting or preventing the admission of water into the reservoir, second valve and conduit means for controlling the level of the water in the reservoir, a pressure gauge for monitoring the pressure at the filter inlet; and control means for controlling the gas feeding means to cause or stop the feeding. The source of pressure may be a compressed gas cylinder provided with valve and conduit means for controlling the admission of compressed gas from the cylinder into the water container, and the means for feeding gas to the filter inlet comprise conduit and valve means for feeding gas to the inlet directly from the gas cylinder.
