Dispensing system

A dispensing system comprising a self-gassing liquid to be dispensed and a dispenser for dispensing said self-gassing liquid, the dispenser comprising:

• a valve housing comprising an inlet for receiving the self-gassing liquid, an outlet through which the self-gassing liquid is to be dispensed, a valve chamber and/or passage extending between the inlet and the outlet, and a valve arranged to open and close the valve chamber and/or passage;
• pressure maintaining means arranged to maintain the self-gassing liquid at the inlet of the valve housing at a constant pressure during successive dispensing operations;
• and
• control means for controlling the opening and closing of the valve, the control means being arranged to open and close the valve to commence and terminate each successive dispensing operation, wherein the control means is arranged to open the valve for a predetermined period of time that is determined by a desired quantity of self-gassing liquid to be dispensed;
• wherein the valve chamber and/or passage is defined by an internal upper surface, an internal lower surface, and one or more internal side surfaces;
• and
• wherein the outlet is located in the internal lower surface or in one of the one or more internal side surfaces at a position remote from the upper surface, the valve chamber and/or passage being arranged so as to provide an uninterrupted upwardly extending path from an uppermost edge of the outlet to the inlet.
