Abstract (en)
[origin: WO0119432A1] A flow-control/flow-regulation element (314) improves the operation of a liquid dispenser. In some embodiments, the flow-regulation/flow-control element (314) comprises a flow restriction that is disposed in the conduit that delivers pressurized liquid to the dispensing valve (310). Since the flow restriction has an orifice (416) that is smaller than the orifice of the dispensing valve (310), liquid is re-supplied to the conduit more slowly than it is dispensed through the dispensing valve (310).
