Abstract
A liquid supply system comprising a liquid reservoir and a liquid container for supplying liquid to the reservoir. Connection means connects the reservoir to a position within the container that is immersed in the contained liquid. Means for alternately pressurising and depressurising the reservoir are provided. The arrangement is such that when the reservoir is pressurised gas is forced into the container through the connection means and accumulates above the liquid in the container. When the reservoir is depressurised accumulated gas in the container forces liquid through the connection means to the reservoir.
