(57) An equipment is described which permits an installation for the distribution of beer
or other beverages, the washing of the pipes in contact with the beverages in a semi-automatic
manner, with no disconnection of any part, with water and gas preferably brought to
the same pressure as that of the beverage in order to prevent infiltration in the
barrels, and in addition permits one or more barrels to be connected and disconnected
by remote control so that the barrels can be changed without disconnecting the coupling,
characterised by the fact that the aforesaid coupling has passages for gas inlets
and beer outlets and an additional passage for washing and that the movements of opening
and closing the coupling itself are effected by means of a pneumatic control.
