Abstract: A faucet which serves for tapping of a liquid such as beer from a container, in which the liquid is under gas pressure. The faucet comprises a casing with an outlet duct and a valve plug placed in this for closing the faucet. In the stream direction, before the valve plug, there is at least one resistance body which is freely, axially slidable in the outlet duct for at least a predetermined distance. This body has a smaller cross section across the stream direction than that of the outlet duct. The dispensing process can automatically be regulated in such a way that a predetermined amount of foam will be present.
